CO2 and temperature transmitters

The GMW80 series also includes temperature measurement as standard. Vaisala's carbon dioxide and temperature transmitters can be used by building automation and integrator companies in order to improve the efficiency of heating, ventilation and air conditioning in a variety of locations, ranging from factories to hospitals to office buildings. 

The transmitters feature the second-generation CARBOCAP sensor and use Microglow technology for reliability and stability. Microglow is a Vaisala-patented, silicon MEMS emitter infrared source. This special low-power, silicon-based infrared source is manufactured in-house at Vaisala. Using this technology, the performance of CARBOCAP sensors has been even further improved. 

With modern buildings often having hundreds of sensors, the installation time per unit can be a significant cost factor. The GMW80 series transmitters include a number of subtle design features that have been introduced to make installation and commissioning quick and easy. 

Vaisala has also improved the functionalities of the sensor to minimise maintenance, further helping to reduce costs. The GMW80 series transmitters are optimised for low maintenance, thanks to the second-generation CARBOCAP sensor.

The internal reference in the CO2 sensor guarantees stability and operation even in constantly occupied buildings without re-adjustment.

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.
