A Rugged, Reliable Solution For Pressure Measurement in Well Automation

Hazardous Environments require highly reliable, rugged instrumentation, especially when it comes to pressure monitoring in a remote environment like oil wellheads. NOSHOK provides a safe, reliable, rugged solution with our 621/622 Series Explosion-Proof Transmitters, and we back them with our industry-leading 3-Year Warranty.

These sensors provide consistently accurate and stable output, stand up to extremely harsh environments, and endure the test of time. The 621/622 Series Transmitters are engineered to the most stringent quality standards and undergo extensive testing, making them ideal for safe, dependable monitoring of tubing and casing pressures in a wellhead.

With an accuracy of ±25% Full Scale (BFSL), combined with the reliability and long life of diffused semiconductor and sputtered thin film, they deliver outstanding performance and value.  All wetted parts are made of 316 Stainless Steel and Elgiloy, and are welded with no internal o-rings, gaskets or seals.

Available in a wide variety of pressure ranges to suit most applications, these transmitters can be specified with a standard threaded connection as well as a flush diaphragm configuration. They are Factory Mutual and CSA Approved to Class 1, Division 1 Explosion Proof, and all models incorporate significant levels of RFI, EMI and ESD protection, and are NACE MR0175/ISO 15156-3:2003 compliant. A low power model is also available.
