CO2, temperature, and humidity transmitters

The new GMW83 suite of transmitters complements the current GMW80 product range, fulfilling customer requirements for standard demand-controlled ventilation and for spaces occupied 24/7. These transmitters are used in a variety of locations, factories, office buildings and hospitals by building automation and integrator companies in order to improve the efficiency of heating, ventilation, and air conditioning.   

The six new GMW83 product versions include models with or without humidity measurement, as well as models with the following options: display, CO2 LED indicator lights, and temperature setpoint.  

Vaisala's carbon dioxide, humidity, and temperature transmitters incorporate the second-generation CARBOCAP technology and use the Microglow light source technology which is said to improve their reliability and stability.

The GMW80 series transmitters include a number of subtle design features that make the installation and commissioning quick and easy. Transmitters are ready for use immediately and will show correct CO2 readings after a two-minute installation without any adjustment period. Vaisala has designed the sensor in a way that minimises maintenance, further helping to reduce costs.

As the power consumption is low, the heat generated by the electronics does not distort the temperature inside the sensor. Moreover, the sensors' operational life is increased by the low operating temperatures.
