Product Description

The Vaisala GMW115 is a compact, wall-mounted carbon dioxide CO2 transmitter for HVAC ventilation control. The Vaisala GMW115 transmitter is fitted with the Vaisala CARBOCAP® CO2 sensor ensuring  excellent long-term stability and years of stable maintenance-free CO2 measurement. The GMW115 CO2 transmitter is easy to install – wire it to the terminal block at the transmitter bottom and close the housing with a snap-on lid to cover the electronics – and is designed to fit standard 2×4″ junction boxes.

 

The superior performance of the Vaisala CARBOCAP® CO2 sensor results largely from the stable reference provided by the electrically tunable Fabry-Perot Interferometer (FPI) incorporated into each sensor.The GMW115 includes 4…20 mA and 0…10V output signals corresponding to 0…5000 ppm CO2. Alternatively, the serial RS-485 output signal can be used.
