SENSOR GMW93D

The wall-mounted Vaisala CARBOCAP® carbon dioxide and temperature transmitter GMW93D is designed for demand-controlled ventilation applications. It features two 0..5/10 V voltage outputs (three-wire cabling) corresponding to carbon dioxide levels of 0...5000 ppm and a 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 gas, a reference meter, 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, low self-heating, 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.
