Hammer Union-WECO® 1502, 2 inch, pressure transmitter
The Stellar Technology WECO® 1502 2-inch hammer union pressure transmitter is a second generation hammer union pressure transducer. It is designed specifically to meet the demanding requirements of hydraulic fracturing in shale oil and shale gas formations.
This 2-inch Stellar Technology hammer union pressure transmitter has been field tested by well servicing companies to validate superior performance, reliability, endurance and service life when compared with competitive units.
WECO® 1502 Hammer Union Product Information
The Stellar Technology WECO® 1502 hammer union pressure transducer is ideal for a wide variety of drilling and well servicing applications. The pressure transducer’s all-welded construction ensures there are no fastener failures. The one-piece Inconel male sub and pressure sensing diaphragm will withstand the sour gas environments encountered in many well servicing applications. A proprietary diaphragm is designed for high-cycle applications.
Since field failure is often due to the failure of the electrical receptacle, Stellar Technology 2-inch 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. A larger housing diameter makes it easier to connect/disconnect cable assemblies.
Each WECO® 1502 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 for the 2-inch pressure transducer 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 1502 nut to be installed without removing the handle, is standard.
The Stellar Technology WECO® 1502 hammer union pressure transducer has a static accuracy of 0.2% of full scale output (BFSL).
The WECO® 1502 comes in standard ranges of:
- 5000 psi
- 6000 psi
- 7500 psi
- 10,000 psi
- 15,000 psi.
Special calibrations to 20,000 psi are also available.
All Stellar Technology WECO® 1502, 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. (See 2202 Hammer Union data sheet for WECO® 2202 specifications. Refer to data sheets for GT23XX and GT25XX product for explosion proof configurations.)
