Description
The PT390 Oil Field Pressure Transmitter is
available in pressure ranges from 5,000 to 20,000
psi. The pressure sensing diaphragm utilizes high
resistance foil strain gages coupled to a sealed
amplifier module. The module produces a 2 - wire,
4 to 20 mA output signal proportional to applied
pressure. Specifically designed to withstand aggressive
oil field applications, the PT390 meets NEMA 4X
environmental standards. Wetted parts are made from
Inconel X - 750 to meet NACE standard MR - 01 -
75 for sour gas service. PT390 accuracy is within
0.25% of full scale pressure including linearity,
hysteresis and repeatability.
Features
Confidence &
Control in the Field
- Larger, tapered
pressure port is easy to clean and drains readily
after washdown
- 100% calibration
output signal makes it easy to set system span
in the field
- For extra environmental
protection, the amplifier module is sealed and
potted in a separate metal enclosure
- Stainless steel
construction, withstands severe shock and vibration
- High resistance,
isolated strain gage bridge offers low power
drain, rapid warm - up time and better stability
