Core Sensors CS81 Intrinsically Safe Low Pressure Transducer

The Core Sensors CS81 intrinsically safe low pressure transducer features all-welded, stainless steel construction for a minimum IP65 rating. The media-isolated design and 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. The sensor also offers reverse polarity and EMI protection. Low power outputs are available that can operate with 3-5VDC of unregulated power to extend battery life in remote applications.
