SERIES EDA Electronic Pressure Control is an extremely versatile compact package that can replace a separate gage, two switches, and a transmitter in a system saving money, installation time, and panel space. The EDA incorporates two SPDT relays that have the on and off points fully adjustable over the range for control or alarm use. Front face has LED indicators for switch status and a large backlight two-line display showing process value and indication units. Programming is easy with simple menu structure, two-line display, and external programming buttons. Weatherproof housing is ideal for a wide variety of applications with panel mount, flush mount, or pipe mount ability. Features include zero set, adjustable dampening, menu lock out, peak and valley indication, removable terminal blocks, adjustable time delay, and scalable transmitter output.

Features:

• Display Units: psi, kg/cm², bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in² (choices depend on range).
• Test Mode: Simulates input over the range without pressuring to easily test switches and transmitter output feature.
• Fail-safe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.
• Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.

The Series LPG5 Low Pressure Gages offer top of the line performance for pressure applications from 10 in. w.c. to 10 psi. The LPG5 gages possess dual scales with 3-2-3% full-scale accuracy on a 2.5" dial. Units are made with a chrome plated steel housing and brass wetted parts. Units can withstand temperatures of -4 to 140°F (-20 to 60°C). This series is meant for the measurement of low pressures of gases and liquids and is ideal for air flow indication, liquid level and draft measurement. Series LPG5 gages are available with either a bottom or back connection option.

Features:

• Chrome plated steel housing and brass wetted parts resist ambient for longer service life in harsh environments
• Low pressure gage provides a selection to meet specific applications
• Specified with high ambient and process temperature ratings mean more robust uses and longer service-life
• Good accuracy gage for value-sensitive applications requiring more precise measurement and where vibration is a concern

Applications:

• Air flow indication
• Liquid level
• Draft measurement
