SENSOR GMW93RA

The wall-mounted Vaisala CARBOCAP® carbon dioxide relative humidity and temperature transmitter GMW93RA is designed for demand-controlled ventilation applications. It features three 0..5/10 V voltage outputs corresponding to carbon dioxide concentration 0...5000 ppm, relative humidity 0..100 %RH, and temperature range -5..55 °C. Each unit is calibrated and supplied with a traceable calibration certificate. The device includes a local display behind a sliding front panel and LED indicators showing carbon dioxide levels. The field-serviceable transmitter can be calibrated if needed using a reference instrument, reference gas, or by replacing the measurement modules, which are available as spare parts. The GMW93RA transmitters use Vaisala HUMICAP® humidity sensors and next-generation CARBOCAP® technology, whose semiconductor-based internal reference measurement ensures measurement accuracy, long-term stability, low self-heating, long service life, and minimizes maintenance requirements. The sensors and transmitter are manufactured in Finland. This product description is an automated translation of the original Finnish description.
