Pressure gauges, flowmeters for hazardous use

Differential pressure (DP) gauges and flowmeters are designed for use where dangerous gases and vapors may exist. Products have a Class 1, Div. 2 (Group B, C, and D atmospheres) rating. Models come with operating ranges from 5 in. water to 1,000 psi differential pressure, and from 0 to 10 gpm flow. Switch and gauge-switch combinations with the Class 1, Div.

Differential pressure (DP) gauges and flowmeters are designed for use where dangerous gases and vapors may exist. Products have a Class 1, Div. 2 (Group B, C, and D atmospheres) rating. Models come with operating ranges from 5 in. water to 1,000 psi differential pressure, and from 0 to 10 gpm flow. Switch and gauge-switch combinations with the Class 1, Div. 2 hazardous ratings are now available in DP models 1203, 1503, 1516, 1803, and 1833, and in flow models 2223 and 2323. Switches are SPST or SPDT and are housed in NEMA 4X watertight (weatherproof) enclosures. www.orangeresearch.com Orange Research
