Transmitters for demand-controlled ventilation

The new GMW83 suite of transmitters complements the current GMW80 product range, meeting customer requirements for standard demand-controlled ventilation and for spaces occupied 24/7. These transmitters are used in a variety of locations in order to improve the efficiency of HVAC systems.   

The GMW83 suite of transmitters is specifically designed for spaces with demand-controlled ventilation. The new 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 Microglow light source technology which is said to improve their reliability and stability. Microglow is a silicon MEMS emitter infrared source. 

The GMW80 series transmitters include a number of subtle design features that make the installation and commissioning quick and easy. The transmitters are ready for use immediately and they will show correct CO2 readings right away 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. The low product life cycle costs are achieved thanks to the second-generation CARBOCAP technology and the latest Microglow technology. These are said to lead to superior stability, lower power consumption and a longer product lifetime.

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.

Vaisala GMW80 series transmitters are designed to give reliable and valid measurements even in spaces occupied 24/7 without readjustments.

Through simplified and intelligent optical design fewer components are required, which helps to increase overall reliability of the sensor. The reliable operation and accurate measurement values of the GMW80 series transmitters contribute to significant cost savings brought by demand-controlled ventilation.
