PROTRAN Pressure Transducer

About the PR3100 High-Precision Pressure Transducer

Robustly constructed from stainless steel this range of pressure transmitters incorporates the latest strain gauge technology together with a custom IC amplifier offering excellent stability and accuracy over a long service life. Output options include 2mV/V, 0-20mA, 0-5Vdc and 0-10Vdc. Electrical connection is via a detachable DIN connector allowing easy access to zero and span adjustment. Standard pressure connection is 1/2”BSP. Optional 1/4”BSP, 1/4”BSPT, 1/2”BSPT, 1/4”NPT, 1/2”NPT are also available on request. In addition PR3100 is available in corrosion resistant materials e.g. Hastalloy C, Inconel etc. Pressure ranges available from 0-1bar to 0-600bar.

An optional ATEX certified version of this product is available approved for explosion protection for flammable gases (zone 0), dusts (zone 20) and mining areas (group I M1).
