GMW95 Carbon Dioxide, Temperature and Humidity Transmitter
Termékleírás
The Vaisala GMW90 series
consists of digital carbon dioxide, temperature, and humidity transmitters, designed for demand-controlled ventilation systems. Equipped with the next-generation CARBOCAP™ sensor, they deliver high accuracy, outstanding long-term stability, and low power consumption. The transmitters are easy to install, feature interchangeable calibrated modules, and support BACnet and Modbus communication.

The GMW90 measures CO₂, temperature, and optionally humidity in one device. The CO₂ range is 0 … 5000 ppm, with an accuracy of ±(30 ppm + 2 % of reading) under standard conditions. The temperature range is −5 … +55 °C, with an accuracy of ±0.5 °C. The relative humidity range is 0 … 95 %RH, with an accuracy between ±2.5 … 5 %RH, depending on the temperature. The sensors are housed in an IP30-rated ABS/PC enclosure (white, RAL9003), and provide digital RS-485 communication with selectable protocols BACnet MS/TP and Modbus RTU. Interchangeable calibration modules for CO₂, temperature, and humidity ensure easy maintenance and reliable performance.
