1 RFT8100 wireless temperature and humidity detection system is composed by wireless temperature detection probes, humidity detection probes and display terminals. Adopting the advanced wireless temperature detection technology, RFT8100 transmits and displays the real time value detected from the local detection probes for the purpose of inspecting temperature and humidity on-site routinely. The alarm relay sends out signal when the temperature and humidity data exceeds or lowers the setting alarm value, and the alarm points can be found quickly by checking the alarm information. RFT8100 also provides curve diagram for checking temperature and humidity variation in short period for equipments management purpose. RFT8100 can achieve the remote monitoring function by transmitting the measured data to DCS monitor centre or equipments management centre thru RS-485 port or Ethernet port. 2 EMC and safety standard IEC61000-4-2 (GB/T17626.2) IEC61000-4-8 (GB/T17626.8) IEC61000-4-4 (GB/T17626.4) IEC61010-1 (GB/T4793.1).
