SENSOR GMW94R

The wall-mounted Vaisala CARBOCAP® carbon dioxide relative humidity and temperature transmitter GMW94R is designed for demand-controlled ventilation applications. It features three 0/4..20 mA current 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 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 GMW94R transmitters use Vaisala HUMICAP humidity sensors and next-generation CARBOCAP® technology, whose semiconductor-based internal reference measurement ensures measurement accuracy, long-term stability, minimal drift, long service life, and minimizes maintenance requirements. The sensor technology and transmitter are manufactured in Finland. This product description is an automated translation of the original Finnish description.
