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.

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display. These transmitters, also called transducers, have two outputs, so you can program them to work as a transmitter, a switch, or both. When they reach their setpoint, they send electrical signals to your programmable logic controller (PLC) to trigger actions in your system. Adjust their reset point anywhere within the setpoint range. To change settings and receive error messages remotely from your PLC or computer, program one of the outputs to use IO Link. You need an IO-Link controller (not included) to connect to your interface.

Buttons on the display let you change your setpoint, measuring range, and other settings. To quickly tell the status of your process, you can program the color of the display to red and green. LEDs on the corners also notify you of your output’s switching status. Rotate the head to view the display from the best angle.

You must calibrate your PLC in order for it to interpret signals from these transmitters. As pressure increases, the output signal from the transmitter will increase. These transmitters only give accurate readings within the rated pressure or vacuum range.

All have an M12 plug to connect to M12 Connectors. When using both switching outputs and an IO-Link controller, they require four wires to connect. For their 4-20mA analog output, they need two wires to connect. View switch wiring diagrams by selecting a part number and clicking Product Detail.

To withstand wet environments, these transmitters have a 316L stainless steel connection and are IP rated. Their IP ratings also mean they’re dust tight and stand up to spraying water and brief submersion. UL and C-UL listed as well as CE marked, they meet strict American, Canadian, and European safety standards.
