SENSOR GMW95RD

The wall-mounted Vaisala CARBOCAP® carbon dioxide relative humidity and temperature transmitter GMW95RD is designed for demand-controlled ventilation applications. It features a digital RS-485 output with Modbus RTU and BACnet MS/TP protocols. The protocol can be field-set without tools. The measurement range is 0...5000 ppm, 0..100 %RH, and -5..55 °C. Each device is calibrated and supplied with a traceable calibration certificate. The device has a continuously readable local display. The field-serviceable transmitter can be calibrated if needed using a reference meter, reference gas, or by replacing the measurement modules, which are available as spare parts. GMW95RD transmitters use Vaisala's HUMICAP® humidity sensors and next-generation CARBOCAP® technology, whose semiconductor-based internal reference measurement ensures measurement accuracy, long-term stability, low self-heating, long lifespan, and minimizes maintenance requirements. The sensors and transmitter are manufactured in Finland. This product description is an automated translation of the original Finnish description.
