At least five times as accurate as standard pressure transmitters, these transmitters sense pressure at an accuracy of ±0.1% and come with a calibration certificate traceable to NIST. They are commonly used in laboratories and testing applications. Also known as transducers, pressure 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 transmitter's pressure range and output signal. 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 IP65 and NEMA 4X for use in washdown and corrosive environments.

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.

Remotely monitor pressure in general purpose applications such as pumping and compressing systems. These transmitters, also known as transducers, convert pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls.

4-20mA current output transmitters connect 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.

DC voltage output transmitters connect using three wires—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 with calibration certificate traceable to NIST include documentation that states they've passed a test for accuracy.
