The CS81 pressure transducer is a high strength sensor designed for low-pressure measurements in intrinsically safe areas. The CS81 features all-welded stainless steel construction for a minimum IP65 rating. A wide range of configurable options makes 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. CS81 is an excellent solution for applications such as external fuel tank monitoring, vapor recovery, and natural gas compression.
