About this file
This is a technical specification datasheet for water level measurement equipment specified for a state or local contract opportunity. The document provides detailed specifications for the SITRANS LR110 Radar level transmitter, manufactured by Siemens (ordering code 7ML53131..060.A0), a non-contact continuous radar-based level measurement device designed for liquids, slurries, and solids with a maximum measuring range of 15 meters (49.2 feet). The equipment features an 80 GHz operating frequency, 8-degree beam angle, and measurement accuracy of 2 mm maximum deviation at the analog output. The transmitter operates under medium temperatures ranging from -40°C to +80°C with operating pressure limits of -1 bar to 3 bar and requires a minimum dielectric constant of 1.6 for the process medium.
The SITRANS LR110 is engineered for harsh environmental conditions with IP66 and IP68 degree of protection ratings, operates on 24V DC external power supply, and includes integrated cable connection with polyurethane (PUR) material. The device incorporates polyvinylidene fluoride (PVDF) materials for the antenna, enclosure, and cable entry components and utilizes Bluetooth and MODBUS RTU communication protocols. The transmitter holds multiple certifications and approvals including CE, CRN, CSA, FCC, FM, and RCM designations, and complies with EC Regulation 1935/2004 for food-contact materials and PED 2014/68/EU pressure equipment directives for gas group 1 and liquid group 1 classification. The device weighs 1.45 kg and features galvanic isolation with recommended fastening bolt torque specifications of 6 Nm and maximum torque of 7 Nm.
