What is required for a pressure sensor to measure frequency conversion water pumps?
Yes, quite right. And the long term stability, accuracy, response time are also important.Probably like any VFD controlled pump application. Matching the transmitter output signal to what the drive's process variable input needs, 2-wire or 3-wire technology, power supply compatability, process connection, environmental rating, electrical connection style, pressure range, materials of construction, and price.
