Description

Vaisala GMW90 Carbon Dioxide (CO2) and Temperature Transmitters are designed for HVAC control in building automation applications.  GMW90 transmitters offer a simple, clean installation and are commonly installed in museums, laboratories, school classrooms, food and beverage plant and general manufacturing facilities.  The full range of Vaisala GMW90 Carbon Dioxide (CO2) and Temperature transmitters incorporate the following options…

 

Vaisala GMW90 CO2 and Temperature Range…

  • GMW93(D) CO2+T,  voltage output (with display)
  • GMW94(D) CO2+T, current output (with display)
  • GMW95(D) CO2+T, digital model (with display)
  • GMW90 CO2+T, configurable analogue/digital model

 

In addition to the standard CO2 and Temperature range, the following models also incorporate and integrated Relative Humidity (HUMICAP® 180R Sensor) to complete the HVAC and ventilation control package

 

  • GMW93R(D) CO2+T+RH, voltage output (with display)
  • GMW93RA CO2+T+RH , voltage output with CO2 indicator LED and display
  • GMW94R(D) CO2+T+RH, current output (with display)
  • GMW95R(D) CO2+T+RH, digital model (with display)
  • GMW90R CO2+T+RH, configurable analogue/digital model

 

Digital models run over the BACnet/Modbus communication. All sensors can be centrally accessed and monitored. Wiring is simple when multiple sensors are installed on the same bus. Sensors can be set up using standardized tools, and the system can be enlarged with additional sensors quickly and conveniently. In addition, parameters influencing measurements, such as pressure or site elevation, can be centrally set and updated.

 

Calibration of  Vaisala GMW90 Series instrumentation is held within the onboard, GM10, co2 module. This can be checked onsite with reference gas, or sent back to Fluidic for calibration.  To reduce downtime, a spare calibrated GM10 module should be held onsite and swapped out as required.  This is a very simple process that our engineers are able to talk you through.  Where appropriate, calibration of the relative humidity HUMICAP® (HTM10) and temperature (TM10) sensor modules can also be carried out in a similar way by Fluidic in our Glasgow office.

 

Vaisala GMW90 Series Carbon Dioxide and Temperature instrumentation offers a unique feature to accompany the minimalist design and hidden wire install of the transmitter range.  The optional decorative cover can be painted or even fitted with a sample of wallpaper to discretely blend the instrument in with your décor.  See product photos above, contact Fluidic for help with product selection to include this feature.

 

Fluidic are a recognised partner of Vaisala CEN (Industrial division) for Scotland and the North of England.  Our instrumentation engineers are product trained and able to help with instrument selection within the full range of Vaisala Relative Humidity and Temperature instruments.
