Pressure Transducers & Sensors
Intrinsically safe 1502 hammer union pressure transducers for drilling, frac and mud pump service.

Matherne's pressure transducer is a high-pressure, high-precision instrument built for oilfield service, in a rugged, corrosion-resistant stainless steel housing. It suits drilling, frac, mud pump and standpipe monitoring, and can feed DAQ systems, digital pressure gauges and analog meters.
Standard ranges are 5,000, 10,000, 15,000 and 20,000 psi, with hammer union connections, H2S sour service versions and an intrinsically safe design for Class 1, Division 1 areas. Matherne also makes the 6-inch E-Gauge, which pairs an analog dial with a digital readout, alarms and over-pressure pump shutdown.
