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.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- RS485
- RS485 is a robust differential serial communication standard often used in factories, farms and buildings where cables may be long or electrically noisy, and it can link many devices on a single pair of wires. When a product lists RS485, it can communicate with industrial sensors, meters and control equipment over longer distances than typical hobby serial wiring.
- Temperature compensation
- Temperature compensation is when a sensor or instrument adjusts its readings to reduce errors caused by changes in temperature. This matters because a sensor's raw output often drifts as conditions warm or cool, so compensation keeps readings more consistent and accurate over time.
