Carbon Dioxide and Temperature Transmitter for Ventilation Control



  • Compact dual-parameter transmitter: measures both CO2 and T
  • Incorporates Vaisala CARBOCAP®, the silicon based NDIR sensor with unique internal referencing
  • Advanced, single-beam, dual wavelength measurement with no moving parts
  • Excellent long-term stability
  • Ideal for ventilation control in all types of occupied spaces including those with around-the- clock occupancy
  • No need for temperature compensation

The Vaisala CARBOCAP® Carbon Dioxide and Temperature Transmitter GMW116 is the compact-size transmitter that measures both carbon dioxide and temperature. The sensor is accurate and durable and it has an excellent long-term stability, which decreases maintenance.

The excellent performance of the Vaisala CARBOCAP® sensors results largely from the stable reference provided by the electrically tunable Fabry-Perot Interferometer (FPI).

In buildings with around-the-clock occupancy (e.g. hospitals, work-places, residential buildings, retirement homes), the assumed background CO2 level reference is simply not applicable. The true internal reference measurement of Vaisala CARBOCAP® CO2 transmitters provides years of stable CO2 measurements.

The GMW116 Transmitter is designed especially for demand controlled ventilation applications with CO2 measurement range of 0 … 2000 ppm and temperature range of 0 ... +50 °C.

With GMW116 there is no need for temperature compensation. The ideal gas temperature behaviour is taken into account automatically.
