Overview
The Dwyer 626-08-GH-P1-E4-S1 is a Series 626 industrial pressure transmitter that converts 0-30 psi gage pressure into a 4-20 mA output. It pairs a highly precise 0.25% full-scale piezo-resistive sensor with a rugged 316L stainless steel oil-filled sensor and a NEMA 4X (IP66) general purpose housing for dependable service in harsh industrial environments. The 316L SS wetted parts make it compatible with a wide range of gases and liquids, from hydraulic oils to chemicals.
Best for
- Compressors, pumping systems, and irrigation equipment
- Hydraulic systems and general industrial process monitoring
- Outdoor and washdown installations needing NEMA 4X protection
- 2-wire current-loop control loops
