The laser-based fine dust/particle sensor detects and quantifies PM2.5/PM10 particles in the ambient air. The transmitter converts the measured value 0...1000 µg/m³ into a BUS signal (Modbus RTU). As an option, the measuring device has a backlit display and potential-free changeover contact. In the version with a backlit LCD display, the measured value and min/max values, the relay status, etc. are displayed. The switching threshold and hysteresis of the changeover contact can be set via bus command. The address, transmission mode/speed, terminating resistor and master/slave function of the bus devices are conveniently configured using innovative DIP switch technology. This means that the devices can be integrated quickly and easily into the system and later parameterized via the master. The bus devices can even be reset to factory settings by the master during operation. In this way, the basic functionality of the device is restored in a matter of seconds. This can happen in the case of incorrect parameterizations of e.g. Offset, switching threshold, display modes etc. may be necessary. The housing with innovative hinge locking technology, double PG, sufficient terminal space and easy-to-connect elevator terminals offers maximum installation freedom and speed. The fine dust measuring device is ideal for use in workplaces, schools, living rooms, medical facilities to minimize damage to the human body (asthma attacks, cardiovascular diseases) caused by air pollution.
