Description


The CS81 intrinsically safe low-pressure transducer from Core Sensors is a high-strength sensor designed for use in low-pressure class I, division 1 intrinsically safe environments. Available with pressure ranges from 1 PSI up to 49 PSI with an all welded stainless steel construction and customisable configurations. The CS81 offers a choice of electrical outputs and various wetted materials. This sensor series has an operating temperature range of -40°C to +85°C, a media temperature range of -40°C to +125°C and an accuracy of ≤±0.25% BFSL.

The CS81 Intrinsically Safe Low-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 CS81 features a configurable design, allowing Core Sensors to tailor the transducer to your application’s operating requirements. The CS81 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.
