The IRS31Pro-UMB passive road sensor is flush-mounted on the road. Due to the two-part housing design, the combined sensor/electronics unit can always be detached for maintenance or calibration.
The following parameters are measured:
- 水膜高度up to 4 mm
- Road surface temperature
- 许多去冰的物质（NACL，MGCL，CACL）的冷冻温度
- Road condition (wet, damp, dry, ice or snow, damp with salt, wet with salt)
- Friction (Grip)
- Ice %.
Optional: Two additional depth temperatures, such as those at 5 cm and 30 cm. The measurement data is provided for additional processing through a standard procedure (Lufft UMB protocol).
- 测量技术：Measurements of conductivity (ice percentage), radar (water film), and NTC (road surface temp.)
- 测量参数：水膜高度up to 4 mm, road surface temperature, freezing temperature for various de-icing materials (NaCl, MgCl, CaCl), road condition (wet, damp, dry, ice or snow, moist with salt, wet with salt), friction, ice %, and two more depth sensors
- Product highlights:Low energy consumption allows for solar operation, and the two-part housing design simplifies maintenance and calibration. Additionally, the radar principle measures water film
- Interfaces:RS485, SDI-12, analog outputs
- 文章编号：8910.U050，8910.U051，8910.U052，8910.U100，8910.U101，8910.U102
Advantages
- Polling via RS485 interface
- Analog outputs in combination with a converter (DACON-8160.UDAC)
- Radar principle to measure water film
- Freezing temperature output starts at a dry-damp threshold that has been established (for example, 10 m in accordance with the new TLS specification)
- Replaceable sensor electronics (for easy calibration or maintenance)
Examples of Use
- It was installed on the runway as a crucial component of the IDS (ice detecting system) and water film height detection at airports (aqua-planning risk)
- For winter maintenance personnel working with road weather stations on roads, highways, and freeways (municipalities, federal states, and provinces)
