Models 434/435/437 Wing Union/Hammer Union Pressure Sensors are engineered for demanding oil and gas applications including stimulation and circulation systems. Featuring an all-welded stainless steel construction with integrated sensor diaphragm and wing union fitting, these transducers provide superior hermetic integrity and minimize media leakage compared to multi-piece designs.
Acidizing, choke manifold, fracturing and cementing, measurement while drilling (MWD), mud pumps/mud logging, new well development and extraction, oil and gas drilling, service and cement trucks, standpipe, stimulation, well head measurement.
