The VPInstruments VP Dew Point Sensor features a robust design and autocalibration functionality. The sensor can connect to VPVision or any other management system via 4-20mA or RS485 (Modbus RTU) connections.

Two dew point measurement ranges are available: -70 to 60°C for standard applications, and -100 to 20°C for extreme dry air applications. Both analog and digital outputs can be used simultaneously, with the RS485 (Modbus RTU) connection handling digital communication while the 4-20mA output can connect to a loop-powered external display. 24VDC power is required.

The sensor includes a built-in alarm function with LED indicator for local status monitoring. Autocalibration ensures long-term measurement stability and reduced maintenance. An optional kit includes the sensor, sample block with bleed valve, cable, and accessories for complete installation.
