GMW90 series Carbon dioxide and temperature and humidity transmitter

User 's Manual

Wall-mounted GMW90 Series CARBOCAP® Carbon dioxide, temperature and humidity transmitters are especially suitable for smart building projects. The series of transmitters measure carbon dioxide and temperature, with additional humidity measurement options. These instruments are equipped with calibration certificates that meet traceability and compliance requirements. Traceability is maintained using intelligent detection modules that can be switched in the field. The transmitter can be integrated into the interior design of the space and installed using an optional decorative cover.

• Ø Parameters to be measured: carbon dioxide, temperature and humidity (optional)
• Ø Adopt the new generation Vaisala CARBOCAP® carbon dioxide sensor with good stability
• Ø A low power low light infrared source is used to measure temperature and humidity accurately on a three parameter instrument
• Ø Installation and maintenance is quick and easy
• Ø Pre - calibrated, user - interchangeable carbon dioxide, temperature and humidity measurement modules
• Ø Three-point traceable CO2 calibration (including calibration certificate issued by Vysala)
  
• Ø Support both analog output and fieldbus communication (Modbus RTU)
• Ø Optional decorative cover allows the transmitter to blend into your interior design
  

Main Advantages:

Easy to install

The GMW90 series transmitter has been designed for quick and easy installation. Each model includes an easy-to-start display. In order to prevent dust and dirt from entering the sensors during construction and installation, these devices can be wired with backplanes alone. Electronic components can be plugged in at the appropriate stage of a later project under construction. This saves installation time in the project.

Easy calibration

Although the transmitter inspection interval is five years, regular maintenance of the instrument ensures a long product life. Calibration is very easy with a replaceable measuring module. Traceability and measurement quality of the sensor can be easily maintained by clamping into a new module calibrated at the Vaisala facility. The instrument can also be calibrated using a handheld meter or a reference gas CO2 bottle. The service interface is easily accessible by simply sliding the cover down. Closing the panel keeps the measurement environment stable during calibration and ensures accurate results.
