High-Accuracy Pressure Transmitters

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 output current. 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.

Tank-Mount Pressure-Regulating Valves for Moisture Removal

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems, these valves automatically reduce a high inlet pressure to a lower, stable outlet pressure. They have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have 45° flared tube outlet fittings for a tight seal on metal tubing. They come with a gauge to monitor inlet pressure from the tank. They are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.

Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

Pressure Transmitters

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 are rated NEMA 4X and IP65 or IP67 and are good for washdown and corrosive environments.

Pressure and Vacuum Transmitters

Monitor and control vacuum pumps, air compressors, and hydraulics. These transmitters convert both pressure and vacuum into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. 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 or vacuum range and output signal. Transmitters will only provide accurate readings within the rated pressure or vacuum range. All transmitters are rated NEMA 4X for use in washdown and corrosive environments.

DIN-Mount Precision Compressed Air Regulators

Mount these regulators to a 35 mm DIN rail with the included bracket. These regulators have an accuracy of ±0.2%. That makes them ideal for sensitive applications where consistent pressure is needed to generate precise force and movement. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after your filters.

To mount them on a wall, remove the DIN bracket and use the included wall-mounting bracket.

Hazardous-Location Pressure Transmitters

FM approved and CSA certified for use in hazardous locations, these transmitters monitor pressure where combustible fumes may be present. Also known as transducers, 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. You will need to calibrate your receiving device for the transmitter's pressure range and output signal for the receiving device to interpret the signal. The output signal from the transmitter increases as the pressure increases. Transmitters will only provide accurate readings within the rated pressure range.

These transmitters are rated IP67 for protection from dust and temporary submersion. They are CE marked, so they meet European safety standards.

With an output current, they 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.

Differential Pressure Transmitters with Electronic Switch Outputs

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.

Adjustable-Range Pressure Transmitters

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.

4 mA to 20 mA Output Signal—Transmitters with output current 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.

1V DC to 5V DC Output Signal—Transmitters with output voltage 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.
