As accurate as the finest laboratory "U" gauges - yet they are made to roll up compactly for easy carrying and to withstand rough usage.

This compact gauge is easy to read and can safely operate at total pressures up to 30 psig. Standard pressure connections are barbed fittings for 3/16" ID tubing; optional 1/8" male NPT connections are also available. Over-pressure protection is built in by means of a blow-out membrane molded in conjunction with the diaphragm.

Designed to provide continuous or on-demand cleaning for receivers and pulse jet systems. Available in either 4, 6 or 10 channels, each unit is the same size, minimizing enclosure space and reducing overall system installation cost. Time-On and Time-Off settings are selected using two potentiometers.

Designed for determining the state of an inline filter. Determines the pressure drop on either side of a filter through its 1/8" female NPT pressure connections, and relates the value to one of three zones: clean, change, or dirty. Suited for filter applications, line loss, valve drop, and other applications where a simple indicator is needed.

The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background.

Simple, setpoint field adjustment. Excellent setpoint integrity.

3 in 1 instrument possessing a digital display gauge, control relay switches, and a transmitter with current output all packed in the popular Photohelic gauge style housing. Ranges of 5" w.c. and greater maintain 0.5% F.S. accuracy. Bi-directional ranges are also available.
