Ultrasonic Level Transmitter

Operating Instructions SITRANS Probe LU240 with mA/HART

The XRS-5 is non-contacting with a measuring range from 0.3 to 8 m (1 to 26 ft). Advanced echo processing ensures reliable data even in conditions with obstructions, turbulence, and foam.

The hermetically sealed CSM rubber face and the PVDF copolymer enclosure are designed for maximum resistance to methane, salt water, caustics, and harsh chemicals common to wastewater installations. With an IP68 degree of protection, this rugged sensor is fully submersible in the event of flood conditions. Use a submergence shield if full submergence is possible in the application. A submergence shield will maintain a high level reading output during submerged conditions.

The low-cost XRS-5 transducer is compatible with a full range of Siemens controllers, from a basic system for high/low alarm or simple pump control, up to advanced control systems with communications, telemetry and SCADA integration capabilities.

Key Applications: wet wells, flumes, weirs, filter beds

Range	0.3 to 8 m (1 to 26 ft)
Maximum Temperature	65 °C (149 °F)
Frequency	44 kHz

Benefits

Narrow beam angle of only 10°
Chemically resistant PVDF copolymer enclosure and CSM rubber face
Measuring range: 8 m (26 ft) for measurement of liquids and slurries
Fully submersible: IP68 degree of protection
Easy installation with 1" NPT or R 1" BSPT connection
