In contrast to most other sensors on the market, the IRS determines the road condition within the sensor itself. This was made possible by means of a high-end microcontroller and a sensor system which consists of the following components: • Surface temperature measurement. Two additional temperature sensors can be connected for measuring temperature under ground. These latter values are not taken into account for determining the road condition. • Multi-frequency measurement • Measurement of salt concentration and freezing temperature • Determination of the water film height on the surface of the sensor. Depending on the measured values the IRS-20/21-software calculates a possible road con- dition based on correlation factors and operates within a temperature range from –20°C to +60°C. For temperature values higher than a nominated temperature TPOS (default value 2ºC) the model recognises the conditions "Dry", "Residual Salt", "Damp" and "Wet". Values below TPOS additionally allow the determination of "Freezing Wetness", "Hoar Frost / Dry Snow" and "Ice / Wet Snow". The IRS-20 can be used only in combination with a Lufft datalogger OPUS 2. The IRS-21 can be connected to any host computer which is able to support one of the communication protocols described in chapter 9. Furthermore, the sensor has the following characteristics: • Compact construction and easy installation • Low maintenance • Resistant to physical and chemical influences • Exchangeable even when installed • Data transmission via RS 485 (IRS-21) • Measurement time < 2s, therefore low energy consumption Technical Documentation IRS20/21 Page 5 of 37 2 Storage conditions Permissible ambient temperature ...............................-30°C ... +70°C Permissible relative humidity ......................................0...100 % rel. humidity 3 Operating Conditions Permissible ambient temperature ..............................-30°C ... +70°C Permissible relative humidity .....................................0...100 % rel. humidity Protection Class..........................................................IP68 4 Approvals Design conforms to CE 5 Quality Warranty period ..........................................................2 years Maintenance interval...................................................annually Technical Documentation IRS20/21 Page 6 of 37 6 System description 6.1 Hardware The sensor consists basically of two components: • Basic housing with connection cables for communication and power supply • Housing cover with sensor electronics and evaluation electronics These two components are joined together by 6 screws. Two concentric circles on the sensor surface provide the measurement values for the multi- frequency measurement. Alonside, in a recess, there are two electrodes that provide infor- mation about salt concentration and thereby the freezing temperature. Additionally, a tem- perature sensor, which determines the surface temperature, is installed in the central elec- trode. Beneath the remainder of the surface is the aerial for the impedance sensor, by means of which the water film height above the cover can be determinded. The printed circuit board, which contains the signal conditioning and evaluation electronics, is also directly connected to the cover. Data is output via an RS485 interface. Important!! Power consumption during measurement is approximately 200 mA. In order to exclude measurement errors through self-heating, the IRS-20/21 should only be supplied with power only for approx. 2s. For the IRS-20 this is controlled by the OPUS2. The IRS-21 must be switched on and off by the control program of the host system. After data interrogation, therefore, the sensor must be free of voltage. The measurement interval must be >1 minute.
