High-Accuracy Vacuum Transmitters

These transmitters, also known as transducers, convert vacuum to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor vacuum or control equipment. As vacuum decreases, 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 vacuum range and output signal. Transmitters will only provide accurate readings within the rated vacuum range.

For the Manufacturer User Manual, click on a part number and select Product Detail.

4 mA to 20 mA Output Signal—Wire Lead Connection

Image of Product. Front orientation. Contains Annotated. Vacuum Transmitters. High-Accuracy Vacuum Transmitters.

These transmitters connect using two wires to send a 4 to 20 mA 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.

Calibration Certificate Traceable to NIST—All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

±0.25% Accuracy—At least four times as accurate as standard vacuum transmitters, these transmitters sense vacuum at an accuracy of ±0.25%, making them ideal for use in laboratories and in analytical testing applications.

IP67 Enclosure Rating and NEMA 4X Enclosure Rating—IP and NEMA rated, these transmitters withstand weather, corrosion, and brief submersion. They’re CE marked, so they meet European safety standards.

High-Accuracy Pressure and Vacuum Transmitters

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.
