PolyGard Air Quality VOC Analog / Digital Transmitter ADTC3-1160 DESCRIPTION The ADTC3-1160 transmitter is a simple, low-cost and low-maintenance VOC transmitter based on modern semi-conductor technology. The transmitter detects the VOC content in air and emits a proportional, linear, analog 4-20 mA / 0-10 V or digital RS 485/ModBus signal. The different housing versions make the ATC3-1160 available to almost any application or environment. In case of restart/voltage breakdown a signal output is set to 100 % for 20 minutes for maximum ventilation. During this time the transmitter adopts the current VOC value as 450 ppm basic value (CO2 equivalent). Due to the thereby output signal there is a basic ventilation (basic value). In case of improvement of the air quality an automatic correction of the basic value is effected. The normal CO2 values are not causing any problems in closed areas but different substances like VOC can be responsible for symptoms like eye irritations, headaches, feebleness, dizziness, as well as diseases and accordingly overexertion like sick-building -syndrome. Beyond measurement of CO2 concentration the IAQ Transmitter detects the air quality similar to human sensation. That's why VOC measurement is the perfect method to define air quality. Furthermore there are a lot of integrated options for measurement and regulation of the temperature. APPLICATION The ADTC3-1160 is an extremely low-cost sensor solution for controlling the indoor climate. By adjusting the air flow rate to the actual demand by controlling the ventilation speed, it helps you decrease your energy consumption and yet have a healthy indoor climate.
