This manual outlines the basic features and functions of the Siemens Echomax XRS-5 series ultrasonic level sensors, which are used together with Siemens Milltronics ultrasonic level monitoring products. The sensor converts electrical pulses from the transceiver into acoustic energy and converts the returning acoustic energy back into electrical energy for the controller, and it has a built-in temperature sensor.
The document covers general safety guidelines including use in hazardous areas, specifications, dimensions, mounting and interconnection. Wiring sections describe direct connection with shielded twisted-pair cable, coaxial cable connection via a junction box, and twisted-pair extension connection, and the appendix gives installation drawings for the XRS-5 and XRS-5C in hazardous locations. This manual is written in Chinese.

The measurement range is 0.3 to 8 m for liquids and slurries.
The sensor series is approved for use only at ambient temperatures from -20 °C to 65 °C.
With RG-62A/U coaxial cable the connection run can be up to 365 m.
The sensor can only be powered by a Milltronics dedicated controller.
