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.
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.

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.

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.

The Series LTS Tilt Switch probes are able to sense either the presence or absence of material when other sensors won't work due to bin vibration, or actual walls aren't available for mounting other types of measuring units. The probes are designed for use where the bulk material to be sensed is exposed or open. Typical applications include high or low level detection in large hoppers, silos, crushers, or trippers, high level control under stackers, and detection of plugged conditions at conveyor transfer points. Series LTS probes can also be used to detect the presence or absence of bulk material on belt conveyors, on chutes to indicate product flow, and to aid in loading rail cars or trucks.
All probe models are airtight, dust tight, and waterproof. The compact probe should be used for applications involving small bins and hoppers where space is limited, while the heavy duty probe should be used for applications where a heavy duty abrasion-resistant probe is necessary.
The probe should be suspended using a fixed support, such as a mounting bracket or S-hook, at a position where it will easily intercept the bulk material at the desired indication point. There must be a free flow of material both to and away from the probe. In some installations, it is necessary to install a baffle or shield above the probe assembly to protect it from product surges.
All wiring should be in compliance with applicable Local, Federal, and State codes. Probe connection cable is 16-3 type SO and is attached to the probe. Probe cable length is supplied as specified per order, and may be spliced.
The Series LTS Tilt Switch Probes are 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 goods authorization number before shipping.

The Model CTF Mini Tuning Fork Level Switch is an ideal choice for level control of powders. The CTF incorporates a piezoelectric crystal that vibrates the fork at its natural frequency. When the fork comes in contact with a material, the vibration is dampened and the switch changes state. As the fork becomes free of material, the switch changes back to its normal state. The unit is not affected by vibration from conveying systems, motors, or the movement of material. Its compact size and DIN connection allow for application in places a larger tuning fork level switch may not be suitable, providing great versatility.
The Model CTF is easy to use with no calibration required, and no mechanical moving parts mean no routine maintenance. The CTF is not affected by the dielectric constant of the sensed material, making it superior to a comparable capacitance level switch for applications where the dielectric constant is low, more than one material is being used in the single vessel, and when material moisture content can change. The level switch is also great for applications when the bulk density is too low for a rotating paddle level switch, making it the ideal choice for low density bulk solids and liquids. Comes standard with a user friendly PNP/NPN configurable output.

Incorporated in the design of the PLS is a magnetic drive that is time proven by decades of use in our Mark Series valve position indicator product line. A 1 rpm synchronous motor rotates the paddle, utilizing a magnetic drive. As product builds up, the paddle is impeded from moving and the resulting motor torque activates the output switches and stops the motor. A spring mechanism reactivates the motor and returns the switches to normal state when the product no longer impedes the paddle rotation.
Standard construction is weatherproof with explosion-proof optional, and the unit can be side or top mounted. The PLS is designed with the industry standard 1-1/4" male NPT connection and mounting flanges..

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).

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.
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.
