Core Sensors CS81 series

New Core Sensors CS81 series

The CS81 intrinsically safe low pressure transducer series from Core Sensors is designed for use in low pressure applications in intrinsically safe areas, with CSA and ABS approvals. Available with pressure ranges from 2 PSI up to 50 PSI with an all welded stainless steel construction and customisable configurations. The CS80 from Core offers a choice of electrical outputs 4-20mA, 1.5V, 1.6V, 10mV/V, 0.5 - 4.5V ratiometric and 0.5V - 2.5V non-ratiometric, various wetted materials including  316L SS and Hastelloy C276. This sensor series has an operating temperature range of -40°C to +85°C with an acuracy of ≤ ±0.25% BFSL.
