The IRS31 and ARS31 passive road sensors are built into the road, flush with the surface. The two-part housing design enables the combined sensor/electronics unit to be exchanged for maintenance or calibration purposes in a matter of minutes. The following measurements are taken: - Road surface temperature - Water film level up to 4mm - Freezing temperature for NACL (others on enquiry) - Road condition (dry/damp/wet/ice or snow/residual salt/freezing) The sensors can be addressed and therefore networked. The measurement data is digitally transmitted via RS485-interface for further processing (logger, PLC etc.)  |
