GP-50 Model 340 Pressure Transmitter

GP:50 announces the release of yet another product to further complete their full line of upstream oilfield pressure and temperature transmitters. Working in conjunction with a major well servicing company, GP:50 developed the Model 340-IM series pressure transmitter specifically designed for blender discharge pressure applications. The Model 340-IM resolved the chronic high failure rates they experienced with other suppliers.

Designed for direct pipe mount via its flush process pipe connection the Model 340 series can handle the pressure and harsh media found on Frac blender trucks.

The Model 340 transmitter offers a compact, all welded, rugged design with a flush faced sensor that resists clogging found with conventional pipe mounted transmitters. With at least 5 times proof pressure, and a machined stainless steel sensing diaphragm, it can withstand erosion from aggregate and survive high pressure spikes typically found in blender applications.

With a proprietary sensor design there is zero installation offset, typically found with flush NPT process devices. Available in 4-20mA, 0-5 VDC or Canbus J1939 outputs and pressure ranges from 0-75 thru 0-1,000 PSI.

GP-50 Range of Pressure Tx’s

GP:50 has developed into a state of the art facility providing pressure instrumentation for industrial pressure application solutions in Aerospace, Melt pressure, Automotive test, Petrochemical, Sub-sea, Sanitary, & hydraulic & pneumatic control.

The ability to customize products gives GP:50 a distinct edge in allowing our customers the product flexibility they require.

With marketplaces ranging from Oil & Gas, Plastic Extrusion, Automotive, Waste water, Military and Aerospace GP:50 has become a global player in the pressure instrumentation industry.
