CS72 Intrinsically Safe Submersible Pressure Transducer

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

The CS72 is an intrinsically safe submersible pressure transducer designed for use in hazardous areas when installed with an approved barrier (See entity parameters on Page 3 of datasheet).  This sensor can either be submerged within the tank or installed externally with threaded connection, maintaining ingress protection for external conditions such as flood prone areas.  The sensor is designed for use with various liquids compatible with stainless steel and PUR cable.
