The NOSHOK 623 / 624 Series Non-Incendive Pressure Transmitters combine the reliability and long life of diffused semiconductor and sputtered thin film strain gauge sensors with safe electronics for outstanding performance and value. These transmitters were designed for applications that require pressure measurement in hazardous environments. The pressure chamber is welded with no internal O-rings, gaskets or seals. The 623 transmitter includes an internal diaphragm while the 624 transmitter utilizes a front flush diaphragm.

The 623 and 624 pressure transmitters are available with a wide variety of pressure ranges 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.

NOSHOK transmitters are available with a standard threaded connection as well as a flush diaphragm configuration and are Factory Mutual approved. All models incorporate significant levels of RFI, EMI and ESD protection. Applications include hydraulic and pneumatic systems, pumps and compressors, test equipment and systems, HVAC systems, power generation, water and wastewater, refrigeration equipment, chemical/petrochemical, marine, pipeline gas compressors, oil field, and offshore.
