CS70 Intrinsically Safe Pressure Transducer

CSA Class 1, Division 1 Groups A, B, C, D, T4
Class 1 Zone 1 AEx ia IIC T4 Gb

The CS70 intrinsically safe pressure transducer is designed for use in hazardous locations with an approved barrier (see datasheet for entity parameters). The sensing element is available in various materials, depending on the liquid or gas being measured. From upstream oil and gas to downstream chemical processing or filling stations, these pressure transducers are designed for both indoor and outdoor applications.  The CS70 can be packaged with 4-20mA current or various voltage output signals and various electrical connections to make installation simple.
