These Hammer Union pressure sensors, or model 425 Wing Union pressure sensors, are made by Honeywell. These durable transmitters were created to be used with Weco® 1502 fittings.
The pressure transmitters are offered in two accuracy levels: Best Fit Straight Line (BFSL) or High Accuracy (BFSL-High Accuracy). Both have been created for difficult situations in land-based or off-shore applications, and are suitable for use in the gas and oil industries as well as in drilling applications. Mud pumping, fracturing and cementing, well head measurement, standpipe, and well stimulation are but a few uses of these pressure sensors. They feature Honeywell's time-tested Wing Union construction.
These one-piece, hermetically sealed stainless steel designs have been completely welded, and provide dependable and precise data to detect pressure changes. This helps operators make quick adjustments to the media flow pressure during drilling operations. Oil withdrawal rates are optimized and dangerous conditions profiled in order to improve operator safety.
