NOSHOK

Series 625 Intrinsically Safe Pressure Transmitter

Hazardous Environment Approved, Vacuum To 120,000 PSIG & 300 PSIA

DESCRIPTION

The NOSHOK Series 625 and 626 pressure transmitters combine the reliability and long life of diffused semiconductor and sputtered thin film straingage sensors with safe electronics for outstanding performance and value.These transmitters were designed for applications that require pressure measurement in hazardous environments. All wetted parts are made of welded stainless steel with no internal O-rings, gaskets or seals.

These transmitters are available with a wide variety of pressure connections, ranges and electrical connections to suit most applications. All units undergo extensive testing during the manufacturing process to ensure that the highest performance is achieved in the demanding environments found in today's applications. The transmitters are available with standard threaded connections and are Factory Mutual and Canadian-Standards Association approved. All models incorporate significant levels of RFI, EMI and ESD protection.

FEATURES

  • Advanced diffused semi-conductor and sputtered thin film sensor for maximum stability
  • High accuracy and long term stability
  • Ranges from vacuum to120,000 psi
