SENSOR GMW94D

The wall-mounted Vaisala CARBOCAP® carbon dioxide and temperature transmitter GMW94D is designed for demand-controlled ventilation applications. It features two 0/4..20 mA analog outputs corresponding to carbon dioxide levels of 0...5000 ppm and temperature range of -5..55 °C. Each unit is calibrated and supplied with a traceable calibration certificate. The device has a local display that is continuously readable. The field-serviceable transmitter can be calibrated if needed using a reference meter, reference gas, or by replacing the measurement module, which are available as spare parts. The GMW90 series transmitters use Vaisala's new generation CARBOCAP® technology, whose internal reference measurement based on semiconductor technology ensures measurement accuracy, long-term stability, long service life, low self-drift, 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.
