Intrinsically Safe Low Pressure Transducer


The CS81 pressure transducer is a high strength sensor designed for low pressure measurements in intrinsically safe areas. The CS81 features an all welded stainless steel construction for a minimum IP65 rating. A wide range of configurable options make the CS81 a versatile pressure transducer that can be designed to operate in some of the harshest conditions. Low power outputs are available which can operate off of 3-5VDC of unregulated power to extend battery life in remote applications. The CS81 is an excellent solution for applications such as external fuel tank monitoring, vapor recovery and natural gas compression.

Caution must be taken when installing and operating the CS81 in known Class I, Division 1 hazardous locations. Please review the Intrinsically Safe Operating Instructions prior to installation.
