Read pressure directly at the source and send data remotely with one device. Also known as transducers, these transmitters convert 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. As pressure increases, the output signal from the transmitter will increase. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the pressure range and output signal of the transmitter. Transmitters will only provide accurate readings within the rated pressure range. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. All transmitters are rated IP67 for protection from temporary submersion. They’re CE marked as compliant with European health, safety, and environmental standards.

All of these transmitters connect using two wires to send a 4-20mA current output. 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. These transmitters also connect using three wires to send a DC voltage output—two wires into the power supply and a separate wire that sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply. Transmitters are commpatible with M12 sockets.
