Hammer Union Sensor (Model P3298)

The Hammer Union pressure sensor is fixed by a so-called hammer or Wing Union directly in the process. The sensor is particularly used in the petrochemical industry as well as in the petroleum and natural gas production.

    Robust and long-term stability during operation are the strengths of this pressure sensor for harsh environments. The used materials and technology make these sensors insensitive to chemically aggressive media and mechanical stress.

    Applications of these extremely robust sensors are the offshore industry, including also blowout preventers (BOP) or the cementing of wells, as well as different areas of natural gas production.

    The wetted parts of these pressure gauges are made of Inconel X-750. All metallic compounds are welded so that the sensor is protected. The electrical connection by Bendix PTIH-10-6P plugs also illustrate the robustness of the structure. The devices are fixed in the process by a so-called Wing Union or Hammer Union. The pressure sensors correspond to the electro-magnetic compatibility (EMC) according to EN 61326.
