CS81 Intrinsically Safe Low Pressure Transducer

Product Description

The CS81 pressure transducer is a high strength sensor designed for low pressure measurements in intrinsically safe areas. The CS81 offers a ±0.25% BFSL FS accuracy and 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.
