Hammer Union Pressure Transducer from Stellar Technology

The Stellar Technology hammer union pressure transducer is ideal for a wide variety of high pressure drilling and well servicing applications. The pressure transducer’s all welded construction ensures there are no fastener failures. The one-piece Inconel 2202 male sub and pressure sensing diaphragm will withstand the sour gas environments encountered in many well servicing applications. Since field failure is often due to the failure of the electrical receptacle, Stellar Technology hammer union pressure transducers incorporate an extra rugged bolt-on receptacle with proprietary shell. Customers can also specify hermetic welded electrical receptacles or their own preferred type of electrical connection.

Each hammer union pressure transducer is manufactured with special processes to enhance shock and vibration immunity—characteristics vital for today’s well servicing environments. Special design features are included to counteract the possible effects of EMI and RFI interference. Additional design features include four equally spaced drain-holes around the connector base to ensure moisture does not build up around the electrical receptacle. A flexible vinyl-covered steel carrying handle, allowing the 2202 nut to be installed without removing the handle, is standard. The Stellar Technology 2202 hammer union pressure transducer has a static accuracy of 0.2% of full scale output (BFSL) and comes in standard ranges of 10,000, 15,000 psi, and 20,000 psi.

All Stellar Technology 2202, 2 inch, hammer union pressure transmitters are ATEX and/or CSA certified intrinsically safe with 4-20 mA output. The part number reference on the following page indicates whether the hammer union pressure transmitter is ATEX certified, CSA certified, or dual certified.
