描述 Description

Model 435 Wing Union Pressure Sensor, 5000 psi, ±0.2 %FSS accuracy, temperature compensated, one-wire shunt calibration, MS Series compatible 4-pin electrical termination (32A-14S-2P-10-M2), Weco? 1502 pressure port, 4-pin standard wiring, and Inconel? X-750 wetted diaphragm.Models 434/435/437 Wing Union/Hammer Union Pressure Sensors are designed for demanding oil and gas applications as well as stimulation and circulation systems. They are constructed as an all-welded, stainless steel assembly with the sensor diaphragm and wing union fitting machined as one part, which provides hermetic integrity and minimizes media leakage versus multi-piece parts. The isolated pressure sensing diaphragm minimizes zero-shift during hammer up and eliminates long-term signal drift in the field. The Weco? 1502, 2002, and 2202 Wing Union-compatible fittings are machined of Inconel? X-750, or optional NACE-compliant Inconel? 718, allowing for use with abrasive and corrosive media. The Honeywell proprietary stainless steel electrical connection provides enhanced secondary pressure containment. Special assembly processes provide enhanced shock and vibration for reliable performance in the field.
