CO2, Humidity and Temperature Transmitter Series GMW80 - 1

GMW80 Series Carbon Dioxide, Humidity, and Temperature Transmitters for DCV Features • Superior stability due to 2nd-generation proprietary CARBOCAP® technology • Improved accuracy due to low self-heating of microglow light source GMW80 series transmitters are designed to fulfill the needs for CO2 measurements in standard demand-controlled ventilation applications. Temperature measurement is always included in the GMW80 series transmitters. Combined with humidity measurement, relay, and LED CO2 level indication, GMW80 series provides you the flexibility needed for a variety of projects. The CARBOCAP sensors measure CO2 accurately immediately when powered on. As they have a built-in reference measurement they do not need a lengthy learning phase before the measured values are correct. Proper operation can be verified immediately after snapping on the device cover. Easy Installation With modern buildings often having hundreds of sensors, installation time per unit can be a significant cost factor. Returning to the building site to check sensor operation adds further costs. The GMW80 series transmitters include a number of subtle design features that have been introduced to make installation and commissioning quick and easy. The pull-out tab makes opening the transmitter faster than before, while also doubling as a quality check slip and holder for the anti-tamper screw. The backplate can be twisted onto premounted screws, and the wiring can be done easily on the clearly marked backplate. The electronics can be snapped on later when the building automation system is commissioned. For measurements in more demanding conditions (for example, dusty or humid installation locations), the GMW88 model provides an IP64-rated enclosure with a cable gland. Reliable Operation The GMW80 series transmitters are optimized for low maintenance. The 2nd-generation, low-power CARBOCAP technology enables a longer lifetime and better stability than ever before. As the power consumption is low, the heat generated by the electronics does not distort the temperature inside the sensor. The internal reference in the CO2 sensor guarantees superior stability and flawless operation even in constantly occupied buildings, without the need for frequent readjustments. The reliable operation and accurate measurement values of the GMW80 series transmitters contribute to the significant cost savings brought by demand-controlled ventilation. • Cost-efficient, affordable • Reliable and maintenance-free operation for up to 15 years • Easy to install, easy to use • Versatile - works well in buildings occupied 24/7 • Ideal for demand-controlled ventilation
