With an internal temperature compensation and accurate distance detection, URM08-RS485 is a combination of temperature measurement device and distance inspection tool. The inner is fully enclosed and the external is made of metal crust, which has brought advantages such as waterproof, dustproof and corrosion resistance… It is applicable to detections of liquid level, levels, and barrier applications. As a high standard sensor, it guarantees smaller blind zone and larger inspection range. On the premise of stable output data, it shows better measurement capabilities in the market of temperature sensors and distance detection sensors.

Jargon buster
Plain-language definitions for the technical terms used above.
- RS485
- RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
- Temperature compensation
- Temperature compensation means the sensor adjusts its readings to reduce errors caused by changes in water temperature. This matters for field monitoring because ponds, rivers, and tanks can vary in temperature throughout the day and across seasons.
