New dew point sensor for refrigerant and desiccant air dryers

VPInstruments has launched their VP dew point sensor, the smart dew point sensor for compressed air and industrial gases. Its large measurement range, -70..+60⁰C, enables one single product for monitoring the dew point of both refrigerant and desiccant type air dryers.

The VP Dew Point Sensor features a robust sensor that fully withstands getting wet and that is highly resistant to particulate contamination, oil vapour and most chemicals. Its long- term high performance is achieved with state-of-the-art polymer technology. Thanks to the built-in offset calibration algorithm, performance at low dew points is optimised.

The dew point sensor enables monitoring of both dew point and temperature simultaneously in VPVision and other energy management systems, thanks to its RS485 (Modbus RTU) output. The sensor also features a 4..20 mA output, that can be connected in parallel e.g. to an external display. With the built-in alarm function, you can make alarms visible in your management software for instance for dryer failure or water carry over. The alarm is also visible via the LED on the VP dew point sensor itself.
