2202 HU Hammer Union Pressure Transmitter


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.
