SENSOR GMW93

The Einäasenteinen Vaisala CARBOCAP® carbon dioxide and temperature transmitter GMW93 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 temperature range of -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 module, which are available as spare parts. The GMW90 series transmitters use Vaisala's new generation CARBOCAP technology, whose semiconductor-based internal reference measurement ensures measurement accuracy, long-term stability, low self-heating, long lifespan, and minimizes maintenance requirements. The sensors and transmitter are manufactured in Finland. This product description is an automated translation of the original Finnish description.
