Monitor and control pressure in portable HVAC systems, hydraulics, and oil and gas equipment. Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature. Also known as transducers, they convert pressure into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls. 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 IP67 for protection from temporary submersion during washdowns.

With a DC voltage output of 0-5V, these 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 brass connections are commonly used in general-purpose applications such as water metering and pumps. Transmitters with aluminum connections are lightweight, weighing about half as much as those with brass connections. They’re often used in automotive applications and jobs where weight is important for performance.
