Remotely monitor the difference in air pressure between two inputs with these transmitters. Also known as transducers, they convert pressure to an electrical signal that is interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. These transmitters are often used to indicate a filter is clogged or help you maintain a certain air pressure in ovens, dryers, and HVAC systems. They mount directly to DIN rail or a flat surface without the need for additional brackets. CE marked, all meet European safety standards. These transmitters are rated NEMA 1 for indoor use.
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.
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. As the differential 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.

Differential Pressure Transmitters with Digital Display for Air
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.
IP66 rated transmitters protect against dust and washdowns. Transmitters that meet IP67 protect against dust and submersion. NEMA 4X rated transmitters protect against dirt, weather, corrosion, and washdowns.

View readings at the source with the dial indicator or remotely using a receiver—these transmitters measure the difference in pressure between two inputs in liquid applications. The dial indicator operates independently of the transmitter 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. You’ll sometimes see them used to indicate a filter is clogged in a pump or cooling system. Rated NEMA 4X, these transmitters protect against dirt, washdown, and corrosion. They are also rated IP65 for protection from dust and rinsing. All are CSA certified, so they meet Canadian safety standards.
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.

Get the flexibility of a differential pressure transmitter and a switch in one. These transmitters can work as a traditional transmitter using an analog output but also have electronic switch outputs and IO Link compatibility, making them great for advanced automation applications. Also known as transducers, they measure the difference in pressure between two inputs and convert it to electrical signal. Connect them to your programmable logic controller or receiving device to monitor differential pressure remotely, activate automated controls, or trigger alarms when they reach the set pressure. A digital display lets you monitor the differential pressure and troubleshoot issues at the source. It rotates for readability.
You’ll often see these transmitters used to indicate a clogged filter or help maintain a certain pressure in HVAC systems, pumps, and cooling systems. NEMA and IP rated, they protect against dirt, dust, corrosion, weather, washdowns, and temporary submersion.
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.

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.

Measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. These transmitters automatically compensate for errors caused by vibration and temperature changes. Use the keypad to set the pressure range, choose the unit of measure, and zero the transmitter. These transmitters 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. They're often used to indicate a filter is clogged or to maintain a certain pressure in HVAC systems, heat exchangers, chillers, and pumps. All transmitters meet IP66 and NEMA 4X for use in washdown and corrosive environments and have a hastelloy diaphragm to resist harsh chemicals.
Transmitters will only provide accurate readings within the rated pressure range. These 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. They can also be configured using three or four wires.

Safe for use in environments where flammable gases and vapors are present, these transmitters measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. They meet NEC safety standards for protection against an explosion. These transmitters automatically compensate for errors caused by vibration and temperature changes. Set the pressure range with the keypad, select the unit of measure, and zero the transmitter. They convert differential pressure into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls, to monitor pressure or control equipment. You’ll often see them used to indicate a clogged filter or help maintain a certain pressure in heat exchangers, chillers, HVAC systems, and pumps. Rated IP66 and NEMA 4X, they protect against dirt, dust, corrosion, weather, and washdowns, and the hastelloy connection protects against harsh chemicals.
Transmitters will only provide accurate readings within the rated pressure range. Most often, these transmitters connect using two wires. The same wire that sends a signal to the receiver also powers the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. Three- and four-wire configurations are also possible.
