Hazardous location transmitters

Model 572 Pressure Sensor

Model 572 Pressure Sensor

Viatran's 572 pressure transmitter is designed specifically for secondary containment applications in oil services applications.

A sealed gage or absolute pressure reference is available for medium to very high pressures, with a containment pressure of 40,000 PSI. The model 572 pressure transducer withstands harsh atmospheres and is built to be submersed in up to 100 feet of water.

The 572 pressure transmitter can be supplied with FM approves for explosionproof, intrinsic safety or non-incendive. The 572 pressure sensor can also be supplied with ATEX intrinsic safety or flameproof or CSA intrinsic safety or explosionproof approvals.

The standard 572 pressure transmitter has an all welded construction that features 1/4-18 NPT thread for installation in low pressure applications and the F-250-C autoclave fitting for the high pressure applications. Optional pressure fittings and electrical terminations are available.
