VU Series Pressure and Vacuum Sensors

Share to:
The VU series is a high-precision digital pressure switch offering compatibility with both compressed air and non corrosive liquids. VU is rated for both vacuum and a low positive pressure range. The main screen shows the curent measured value in red or green, while two sub-screens can display the setting label and its numeric value in orange. Delay time for the switch output can be as brief as 1.5 ms, while current consumption is held to 35 mA or less.VU is UL/CSA, CE and RoHS compliant.
