APG Hammer Union Pressure Transmitter HU-2202

APG Hammer Union Pressure Transmitter HU-2202

Like all of our pressure transmitters the hammer union pressure transducer uses piezoresistive principles to monitor pressure on a diaphragm. The real difference is how it’s constructed to handle the shock, vibration, weather, and rough handling that prevails on a drilling or production rig. The Hammer Union Pressure Transmitter is an designed for the rugged environments of land based and offshore drilling installations including Mud Logging and Measurement while drilling.

Durability in a smaller package. Our hammer union pressure transducers are built for the most punishing conditions. They're specialists in high vibration and shock applications common on the oil rig. To answer the need for a hammer union pressure transducer that could ship quickly and take the punishment, we designed one from the ground up. It's packed with useful features that make it the easiest to use and install. More importantly, it can handle the intense vibration and shock from being tossed around, hammered, and shaken in applications like Measurement While Drilling. The 2202 HU ships faster and lasts longer than any competitor model, allowing you to focus on safely doing your job.
