Level Indicator

Product Details:

The very affordable Series WD2 detects leaking conductive fluids and alarms to prevent the leak from creating costly damage. The WD2 relies on the electrical conductivity of water to change the resistance across the two contacts located at the base of the enclosure. Model WD2-BP2 is battery powered, provides audible alarm, LED visual alarm, and a SSR output. Also featured is a low battery warning. WD2-LP units are line powered and include a green power indication LED.

Mounting bracket A-154 is perfect for use in leak pans where it is desired to raise the sensing level above the bottom of the pan to eliminate nuisance alarms. The bracket can be mounted to the bottom of the pan and the height of the WD2 adjusted anywhere up to 1.75 ¿¿ (44.5 mm). Or the bracket can be used to mount the WD2 to the side of the drip pan or any side wall at desired height.

Specification:

• Electrical Rating : WD2-BP2: Pilot duty rating 250 mA @ 24 VDC maximum; WD2-LP: 1 A @ 24 VAC/DC, 1 A @ 120 VAC.
• Audible Alarm : BP Models: 10 seconds on, 30 seconds off. LP Models: Continually on. None on D2 model.
• LED Alarm : BP Models: 10 seconds off, 30 seconds on. Two red LED’s; LP Models: Continually on. Eight red LED’s.
• Power Requirements : BP models: 3 V CR2450 lithium metal battery, installed non-functional, user replaceable; LP Models; 11 to 27 VAC/DC.
• Power Consumption : BP Models: 0.9 mA steady state non-alarm, 3.0 mA during audible alarm, 2.4 mA during LED alarm; LP Models: DC power: 25 mA typical and 75 mA maximum, AC power: 30 mA typical and 85 mA maximum.
• Weight : WD2-BP2: 3.5 oz; WD2-LP: 4.3 oz; WD2-LP-D: 5.6 oz.

 

Operation:
Model WD2-BP2 is battery powered, provides audible alarm, red LED visual alarm, and a SSR output. When conductive fluid is detected, the audible alarm will turn on for 10 seconds followed by a 30 second visual alarm repeated until the unit no longer detects fluid. The SSR will change state from open to closed. When the battery gets low the WD2 gives a warning by turning on the visual and audio alarms.
WD2-LP units require an 11 to 27 VAC/DC power supply. A green power LED illuminates when the unit has power. WD2-LP units provide audible alarm, red LED visual alarm, and either a SPDT or DPDT output. When conductive fluid is detected, the audible alarm and visual alarm will turn on and stay on. The relay will change state with open contacts going to closed and closed contacts going to open.

Mounting:
The unit is made to place on a horizontal surface where leaking fluid can build up.
Mounting bracket A-154 is perfect for use in leak pans where it is desired to raise the sensing level above the bottom of the pan to eliminate nuisance alarms. The bracket can be mounted to the bottom of the pan and the height of the WD2 adjusted anywhere up to 1.75 ¿¿ (44.5 mm). Or thebracket can be used to mount the WD2 to the side of the drip pan or any side wall at a desired height.
The A-154 includes one “U” bracket and two “L” brackets. For bottom mounting unscrew the body screws in the top of the WD2. Install the “L” brackets to the “U” bracket sides using the screws and nuts provided. Keep the screws loose for later adjustment of WD2 height. Place the “U” bracket on the top of the WD2 and line up the holes in the bracket with those in the body. The A-154 includes longer body screws that are used to now screw down both the bracket and the body top. The “U” bracket can be mounted in the up or down orientation but it must be mounted “down” to reach the full 1.75 ¿¿ height potential.

Product Details:

The SERIES OLS Optical Level Switches are a low cost, rugged optical level switch that indicates the presence or absence of liquid via infrared light that is reflected back through the prism lens. It also provides rapid response while employing no moving parts for stable process control. The bright red and green LED’s indicate the presence or absence of liquid for true, local indication. Three optional materials, 316 SS, polysulfone and PFA provide application flexibility. Compact switch can be quickly mounted horizontally or vertically for each installation.

Principles Of Operation:
The optical level switch employs an LED, which transmits infrared light. This light is sent through a prism and reflected back to a photo-transistor utilizing two 90° light reflections. With the prism surrounded by a gas, the light source is cast back to the photo-transistor. When a translucent liquid is introduced to the prism at or above the point where the light source makes contact with the prism, the light is reflected into the liquid, not allowing the photo-transistor to energize.

 

Features:

• Compact switch can be quickly mounted horizontally or vertically for each installation
• Bright red and green LED’s indicate the presence or absence of liquid for true, local indication
• Provides rapid response while employing no moving parts for stable process control

Product Details:

Control the level of liquids in filling or draining reservoirs and tanks with the Series CFS. The mercury-free switch is designed  with  an  inverter  microswitch  housed  in  a polypropylene cover. The unit includes a counterweight to adjust the stop and start levels of pump up/pump down
application.

Installation Instructions:
The installation is very easy by holding the cable with a small clamp  in  the  reservoir  or  container.  By  fixing  the counterweight to the cable, at a closer or farther from position float, the desired differential between the highest and lowest level can be freely adjusted. Several differentials between levels, against counterweight-to-float distance are given:

Installation of Counterweight:

• Insert the cable in the counterweight, from the conical part and rotate it, thus causing the plastic ring inserted in
• the opening to become detached (if necessary this operation can be facilitated with the use of a screwdriver). The ring should then be positioned in the point where it is desired to block the counterweight.
• Force the counterweight on the ring by rotating it, using a slight pressure.
• If the counterweight position is to be changed, the counterweight should be retracted, the ring position changed and secured once again.

One of our most versatile level controls, the Series 190 can be used on all types of tank or sump level control applications.

Mercoid® Displacer Controls use displacers that do not float on the surface of liquids, but are suspended on a coil spring. They work on the principle that submerged solids weigh less in liquids, and as the liquid level rises and their weight decreases, the tension on the spring by which they are suspended is decreased. Because they work on a different principle than float type liquid level controls, displacers are not affected by turbulence or pressure, and are excellent for applications with viscous or dirty liquids.

Operating Principle:
Ultrasound is sound with a frequency greater than the upper limit of human hearing; approximately 20 kilohertz. The ULT contains an ultrasonic transducer and a temperature sensing element. The ultrasonic transducer transmits ultrasound wave pulses through air directed towards the material of which the level is desired. The ultrasound waves then reflect off of the material as an echo and travel back to the transducer. The level of the material is determined by the transit time of the ultrasound wave pulse from the sensor to material and for the echo to come back to the sensor. The speed of sound through air is sensitive to the air temperature. The ULT uses the temperature sensing element to compensate for air temperature changes. 

The ULT incorporates patented surface processing technology and adaptive signal processing. Surface processing technology filters out all signal obstructions that may be in the tank creating an effecting beam diameter of only 3 ̋ (7.6 cm).

The Series EBV Electric Bin Vibrator incorporates adjustable force features without creating irritating noise. The low amperage draw at 120V reduces power consumption and makes the vibrators usable in any application. The EBV eliminates drawbacks associated with non-adjustable constant force units. The conventional fix force units are sized with narrow operating limits and may not move material from bins or pack material in containers if the moisture content changes. The adjustable force feature increases application flexibility; reducing equipment downtime and labor expense. The EBV is capable of running continuously at 100% force output without overheating or mechanical damage.

Applications:

• Bin Vents
• Bag Houses
• Dust Collectors

 

Installation:

• Before installation, especially if the apparatus has been stored in the warehouse, remove the side covers from the weights and check to make sure the shaft turns freely.
• The EBV electric vibrator can be installed in any position. Fix the electric vibrator on a rigid area to avoid induced vibrations causing breakage or cracks; if this is not possible, use plates and ribbing for reinforcement.
• The mounting surface must be level (max 0.25 mm/ max 0.01 in) so that the vibrator feet rest uniformly and perfectly in contact with the mounting surface, to avoid internal stresses which can lead to breakage of the vibrator feett.
• To mount the electric vibrator, use bolts, nuts and flat washers.
• Remember that most breakdowns are due to incorrect mounting.
• Anchor the electric vibrator using a chain with a length and cross section suitable for supporting the electric vibrator with a maximum fall of 15 cm (6 inches), in case of accidental detachment.

Maintenance:
Before carrying out any maintenance or cleaning on the machine, make sure the conditions are safe.

Product Details:

Series APV-C Piston Vibrators are air cushioned to provide low noise. This makes it suitable for quiet area applications. It is a good solution to prevent clogs on tank walls and material delivery problems. It can also be applied on vibrating separators and conveyors.

 

Working Principle APV-C:
There are air-breathing tubes located in both ends of the cylinder. Compressed air pushes the piston from one side to the other side. Vibration power arises as the piston moves back and forth in the body. Air cushion at both ends produced by the to-and-fro compression will keep the piston from striking the body. Therefore, the piston will not produce much noise.

Series APV-I impact version piston vibrators can help to get rid of dust or material accumulated inside of pipes or tanks. It allows direct impact on the tank with low specific gravity and high moisture materials inside. It also helps prevent material build-up, pipe clogs, and rust.

Working Principle APV-I:
There are air-breathing tubes located in both sides of the cylinder. Compressed air pushes the piston away from one side and to the other side. Vibration arises when the piston moves back and forth in the body. Air cushion at the top end is produced by the to-and-fro compression. This will keep the piston from striking onto the body top. The piston will strike directly on the bottom side of the body to produce a strong impact. 

How IT Operates:
There are air-breathing tubes located in both ends of the cylinder. Compressed air pushes the piston from one side to the other. Vibration power arises when the piston moves back and forth in the body. In APV-C air cushion at both ends produced by the to-and-fro motion will keep the piston from striking the body. Therefore, the piston will not produce much noise. In APV-I, air cushion at the top end is produced by the to-and-fro compression. This will keep the piston from striking onto the body top. The piston will strike directly on the bottom side of the body to produce a strong impact.

 

Features:

• High strength aluminum alloy housing
• Frequency and amplitude of vibration can be adjusted as needed
• Low frequency and direct impact models available
• Air Connection : 1/8" BSPT female with 1/4" OD push to connect adapter on APV-C1 and APV-I1. 1/4" BSPT female with 1/4" OD push to connect adapter on APV-C2, APV-C3, APV-I2 and APV-I3. Also includes muffler for exhaust port.

 

Applications:

• Bin vents
• Bag houses
• Dust collectors

 

Maintenance:
Upon final installation of the Series APV Piston Vibrator, no routine maintenance is required. A periodic check of the system calibration is recommended. The Series APV is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return good authorization number before shipping.
