Designed for control applications that require high reliability and repeatability, these regulators translate electrical signals to output pressure. As the input signal current increases, the output pressure increases proportionally within the regulating range. Use with sensors that produce the required input signal current or programmable logic controllers (PLC) for automatic setting adjustments.
All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. The enclosure meets NEMA 4X for protection from dirt, washdowns, and corrosion. Install these regulators in your air line after filters.

Keep an eye on the output pressure in high-flow applications—these regulators have a display so you can monitor your application locally. Designed for control applications that require high reliability and repeatability, regulators translate electrical signals to output pressure. As the input signal current increases, the output pressure increases proportionally within the regulating range. Use with sensors that produce the required input signal current or programmable logic controllers (PLC) for automatic setting adjustments. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Regulators with an LED display have multiple functions, including outlet pressure, pressure scale (psi or bar), minimum pressure, and maximum pressure (within the regulating range). Enclosure meets IP65 for protection from dust and water spray.

Pressure Transmitters
![](/prerenderstable/mvPRE/contents/gfx/imagecache/319/3196k57c1-c02c-digital-master1570120694-p9@halfx_637056996600541528.png?ver=imagenotfound)
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. 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. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.
Transmitters with voltage output 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.
Transmitters are rated NEMA 4X and IP65 or IP67 and are good for washdown and corrosive environments.

Fine-tune the pressure range on these transmitters to account for changes in pressure readings over time. With an adjustable range, also known as adjustable zero and adjustable span, the top and bottom of the pressure range can be changed by up to 5%. This saves you from having to make corrections on receiving devices, such as programmable logic controllers (PLCs), remote displays, and motor speed controls. These transmitters, often called transducers, convert pressure to an electrical signal that is interpreted by receiving devices to monitor pressure or control equipment. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.
Rated NEMA 4X, these transmitters stand up to washdowns and corrosion.
Transmitters with current output 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.
Transmitters with voltage output 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.

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.

Account for changes in vacuum readings over time by fine-tuning the vacuum range on these transmitters. Also known as adjustable zero or adjustable span, you can change the top and bottom of the vacuum range by up to 5%. This saves you from having to make corrections on receiving devices, such as programmable logic controllers (PLCs), remote displays, and motor speed controls. These transmitters, often called transducers, convert vacuum to an electrical signal that is interpreted by receiving devices to monitor vacuum or control equipment. As vacuum decreases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated vacuum range.
Rated NEMA 4X, these transmitters stand up to washdowns and corrosion.
Transmitters with current output 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.
Transmitters with voltage output 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.
