Pressure Transmitter with Low-power Voltage Output

The PMP71 consumes less power in operation, making it suitable for solar- or battery-powered applications, such as remote wellheads.

Endress+Hauser added a 1-5 VDC Low Power output option to the PMP71 pressure transmitter that draws only 17 milliwatts of power at 9V, making the PMP71 consume less power during operation than any other voltage-output pressure transmitter in the market This low-power draw makes the PMP71 ideally 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.
