Deliver a large volume of air at a steady pressure for precise, repeatable movement in cylinders, actuators, and automated systems. No matter how irregular your compressed air supply pressure is, these precision regulators have a flexible diaphragm that automatically adjusts to input pressure changes and an aspirator tube that creates a feedback loop to maintain set pressure within a tight band.

Check the difference in air pressure between two inputs at the source using the dial indicator or remotely using a receiver. The dial indicator on these transmitters operates independently and shows differential pressure in real time for troubleshooting. Also known as transducers, these transmitters convert pressure to an electrical signal that is interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. They are often used to indicate a filter is clogged or help you maintain a certain air pressure in ovens, dryers, and HVAC systems. All are CE marked, so they meet European safety standards.

When measuring pressure in ductwork, pair them with a static pressure probe.

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. As differential pressure increases, the output signal from the transmitter will increase. 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.

At least twice as accurate as standard transmitters, these transmitters sense differential pressure at an accuracy of ±0.25%. Use them in laboratories or testing applications where the difference in pressure between two points needs to be measured with high accuracy. These transmitters are often used to indicate a filter is clogged or help you maintain a certain pressure in pumps, HVAC, cooling, and other air and liquid systems. They 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. All transmitters are rated NEMA 4 for protection in washdown environments.
