At least four times as accurate as standard pressure transmitters, these transmitters are ideal for use in laboratories and analytical testing applications. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. 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.

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.

All transmitters are CE marked, meaning they meet European safety standards. NEMA 4X rated transmitters are for use in washdown and corrosive environments. IP67 rated transmitters are protected from temporary submersion during washdowns.

With an accuracy of ±0.25%, use these transmitters in applications that require highly accurate measurement of both pressure and vacuum, such as activating vacuum pumps. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They 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.

Rated IP67 and NEMA 4X, these transmitters seal out dust and water from temporary submersion. All are CE marked, so they meet European safety standards.

With a digital display and selectable differential pressure ranges, these transmitters are a versatile alternative to transmitters with dial indicators. Unlike a standard transmitter that has one wider differential pressure range, these transmitters have multiple ranges to choose from. The selectable pressure range means they are more accurate than standard transmitters since their accuracy applies to each small range rather than a single wide range. They can also be configured to output either current or voltage, while standard transmitters typically output one signal type. The digital display allows you to troubleshoot and monitor differential pressure at the source. Also known as transducers, they measure the difference in pressure between two inputs and convert it to an electrical signal that can be 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 rated UL 94 V-0, so they meet flammability standards. CE marked, they also meet European safety standards.

When measuring pressure in ductwork, pair them with a static pressure probe. Transmitters with an 8" pressure probe cable include 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 when using the 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. For voltage output, connect them using three wires—two wires into the power supply and a separate wire to send a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

DIN-rail/surface mount transmitters give you mounting flexibility. They include the bracket you'll need for mounting it to DIN rail.

Transmitters with a calibration certificate traceable to NIST have passed tests for accuracy.

Transmitters that meet IP67 protect against dust and submersion.
