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 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.
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.

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 and IP rated, all stand up to weather, corrosion, and water from washdowns. IP67 rated transmitters also seal out water from temporary submersion.

Low-Pressure Differential Pressure Transmitters

- For Use With: Air, Argon, Nitrogen
- Accuracy: ±1%
- Tube Connection Type: Barbed
- Housing Material: Polycarbonate
- Temperature Range: 32° to 122° F
These transmitters are commonly used to monitor airflow and to indicate when filters in HVAC systems become clogged. They convert the difference in pressure between two points in a low-pressure system into 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. Transmitters will only provide accurate readings within the rated pressure range. They come with a calibration certificate traceable to NIST. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. All transmitters are rated IP67 for protection in washdown environments.
These transmitters connect using three wires—two wires into the power supply and a separate wire that sends a voltage signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

- Accuracy: ±0.25%
- Pipe Connection: NPT Male
- Housing Material: 304 Stainless Steel
- Connection Material: 17-4 PH Stainless Steel
- Temperature Range: -40° to 255° F
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.
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.
