The CS80 intrinsically safe pressure transducer from Core Sensors is a high-strength sensor designed for use in class I, division 1 intrinsically safe environments. Available with pressure ranges from 50 PSI up to 30,000 PSI with an all welded stainless steel construction and customisable configurations. The CS80 offers a choice of electrical outputs and various wetted materials. This sensor series has an operating temperature range of -40°C to +80°C with an accuracy of ≤±0.25% BFSL.
The CS80 Intrinsically Safe Pressure Transducer is certified by CSA to operate safely in Class I, Division 1 Intrinsically Safe rated locations when used with an approved current limiting barrier. The CS80 features a configurable design, allowing Core Sensors to tailor the transducer to your applications operating requirements. The CS80 is offered in a low power configuration, capable of operating from an unregulated power supply of 3-5VDC and consuming 3mA or less of current.
