When low-power consumption is critical for off-shore applications, this low-power pressure transmitter may be a good choice. The PMP71 pressure transmitter has a 1-5 Vdc Low Power output option that draws only 17 milliwatts of power at 9V, thus it consumes less power during operation than other voltage-output pressure transmitters in the market. This low-power draw makes the PMP71 suited for battery- and solar-powered applications, such as remote oil & gas wellheads, offshore platforms or pumping stations where low power consumption is critical.
The PMP71 measures absolute and gauge pressure of gas, steam or liquid and has built-in algorithms to calculate level, volume and mass of liquids. Measuring spans are available in ranges from -6 to +6 psi up to -15 to 10,500 psi. For safe operation at process temperatures up to 752°F, it has a piezo resistive measuring cell and metallic welded process isolating diaphragm.
The PMP71 has ATEX, FM, CSA, NEPSI, IECEx approvals and is suitable for use in up to SIL3 hazardous applications. The voltage output version is available with the CSA C/US XP approval in North America.
