Road Surface Temperature is measured on site in the asphalt road, preferably in each lane. The road sensors are suitable for dense asphalt or asphalt with an open structure or brick pavement
Mierij Meteo Road Surface Temperature sensors are manufactured to withstand all forces which are applied to the roads surface due to the traffic as well the influences of heat, cold, rain and ice. The sensor is duplex (2 internal sensors). So if the sensor is malfunctioning, the other (internal) sensor can be connected until the whole sensor can be replaced. If necessary, deep soil temperature sensors can be used. The standard Road Surface Temperature sensor is equiped with an accurate 2,252 K NTC resistor.
| Sensor Type | NTC 2252 KΩ @25°C (duplex) |
| Operating Range | -20...+80°C |
| Accuracy | ±0,1°C @ 0°C |
| Response time | < 0,5s |
| Dimensions | Ø 3,5 mm / length 225 mm |
| Material | Stainless steel 316 |
| Cable lenght | 15 m (Rxx cable*) / Additional length on request |
| * Rxx cable can withstand high temperatures for short term while fixing the cable into the concrete road surface with compound. | |
