Used with pumps, cooling systems, and other liquid applications, these transmitters remotely measure the difference in pressure between two inputs. They are also known as transducers. These transmitters convert differential pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. You’ll often see them used to indicate a filter is clogged.

For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's differential pressure range and output signal. Transmitters will only provide accurate readings within the rated pressure range. Connect them using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.

IP66 rated transmitters are dust tight and protect against washdowns. NEMA 4X rated transmitters protect against weather, washdowns, and corrosion.
