Model 424 Wing Union/Hammer Union Pressure Sensors DESCRIPTION The Model 424 Wing Union Pressure Sensors are rugged process which also ensures hermetic integrity for all field condi - sensors designed for use with 2002 and 2202 wing unions in tions. These sensors incorporate special assembly processes demanding land-based and off-shore applications. to vibration and shock proof the components to ensure perfor- mance is maintained during the rigors of fracturing and ce- The isolated pressure sensing diaphragm minimizes zero shift menting applications. The Model 424 Wing Union is machined during hammer-up and eliminates long-term signal drift in the of Inconel X-750, providing service with highly abrasive and field. The sensor diaphragm and wing union fitting are machined corrosive media. as one part. Model 424 is constructed as an all-welded assem- bly using a deep penetration, proprietary, electron beam welding FEATURES POTENTIAL APPLICATIONS Quick deliver y service Acidizing Inconel X-750 wetted parts for additional durability with Choke manifold abrasive or corrosive media Fracturing and cementing 0.2 % accuracy BFSL Mud pumps / mud logging Rugged, robust design New well development and extraction RFI/EMI protected Oil and gas drilling Optional on-board temperature sensor Service and cement trucks Optional one wire (with IS approval) or two-wire (without Standpipe IS approval) shunt calibration allows users the ability to Stimulation validate the offset signal in the field, ensuring the sensor is Well head measurement actively plugged into the system Intrinsically safe CE approved CSA/ATEX cer tificationModel 424 PERFORMANCE SPECIFICATIONS MECHANICAL SPECIFICATIONS Characteristic Measure Characteristic Measure Pressure ranges 0 psi to 5000 psi 0 psi to 6000 psi 0 psi Media Corrosive and abrasive service, to 10000 psi 0 psi to 15000 psi 0 psi to Inconel X-750 20000 psi 0 bar to 350 bar 0 bar to 400 Overload, safe 150 % rated full scale pressure or limit bar 0 bar to 700 bar 0 bar to 1000 bar of WECO 2002 and 2202 fitting 0 bar to 1350 bar Overload, burst 250 % rated pressure or limit of WECO 1 Accuracy 0.2 % best fit straight line 2002 and 2202 fittings Calibration Standard 5-point calibration: Pressure port WECO 2002 and 2202 wing union, 51 0 %, 50 %, and 100 % of full scale mm 2 in pipe, male sub end Output 4 mA to 20 mA, two-wire Wetted parts material Inconel X-750 Resolution Infinite Weight 2357 g 5.2 lb Case material 316L stainless steel (labels are welded stainless steel with embossed charac- ENVIRONMENTAL SPECIFICATIONS ters) Characteristic Measure Temperature, operating -43 C to 85 C -45 F to 185 F INTERNAL AMPLIFIERS Temperature, -34 C to 82 C -30 F to 180 F compensating Amplifier Intrinsically safe amp: specifications Option 2n(2N)*** Temperature effect, zero 0.018 % full scale/C 0.01 % full scale/F 4 mA to 20 mA Output signal Temperature effect, span 0.018 % reading/C 0.01 % reading/F 9 Vdc to 28 Vdc Input power (voltage) Temperature effect, sealing Her metically sealed IP68/NEMA 6P 4 mA to 24 mA Input power (current) 2500 Hz Frequency response (amp) 60 db Power supply rejection ELECTRICAL SPECIFICATIONS -43 C to 85 C -45 F to 185 F Operating temperature Characteristic Measure Yes Reverse voltage protection Supply voltage 9 Vdc to 28 Vdc Yes Short circuit protection Insulation resistance >100 MOhm 50 Vdc Wiring code: connector (std) A No connection Max. loop resistance 950 ohm 28 V decreasing linearly to B (+) Output 0 ohm 9 V C (+) Supply Circuit protection Reverse polarity protection of supply D Case ground leads RFI/EMI protection Noise immunity from 5000 Hz to 1 GHz *** See Honeywells Web site (
