Honeywell’s Model 425 Wing Union/Hammer Union Pressure Sensors are rugged devices designed for use with Weco® 1502 fittings for both offshore and land-based oil and gas applications.

Available in two accuracy levels [±0.2% BFSL (Best Fit Straight Line) - Standard] or (±0.1% BFSL - High Accuracy), Model 425 is typically used in demanding applications such as well stimulation and circulation systems. The higher accuracy option at ±0.1% full scale provides more confidence in the actual measured pressure value, particularly for smaller changes in pressure, allowing drilling operation adjustments as needed.

Model 425 is constructed as an all-welded, stainless steel assembly with the sensor diaphragm and wing union fitting machined as one part. This helps ensure hermetic integrity, which lessens the chance of media leakage vs. multi-piece parts, and increases reliability. The isolated, pressure sensing diaphragm minimizes zero-shift during hammer up and eliminates long term, signal drift in the field. The Weco® 1502 (2 in.)

Wing Union compatible fittings are machined of Inconel® X-750, which provides additional durability with highly abrasive and corrosive media, while the Honeywell proprietary stainless steel electrical connection delivers enhanced secondary pressure containment.
Each sensor undergoes special assembly processes to test shock and vibration for reliable performance in the field.
