EA Series
PRESSURE TRANSDUCER
The EA manifold mount is designed for OEM uses requiring high output
and corrosion resistance. It has operated through millions of pressure
cycles without damage and is well-suited for the high cycle rates found in
automatic equipment, robots, and hydraulic systems.
The EA has been approved by Underwriters Laboratories as a component
in float and pressure operated motor controllers (file #E93356). Its pressure
port, amplifier, and voltage supply regulator are packaged in a Valox case. A
mating electrical connector is included with this low price transducer.
The EAF version outputs a low frequency signal which is ideal for
electrically noisy environments as well as applications requiring long
distance signal transmission or an interface to a microprocessor. The output
signal is a frequency modulated square wave set from 1 kHz to 6 kHz.
