The series comprises three products: the Sitrans LR100 for basic measurement (4-20mA) up to 8 meters; the Sitrans LR110 with communication (4-20mA+HART or Modbus RTU) and explosive atmosphere approval options with a range of up to 15 meters; and the Sitrans LR120 with communication (4-20mA+HART or Modbus RTU), a longer range of up to 30 meters, and an optional immersion shield for flood protection. Powered by a 2-wire loop with optional HART or Modbus RTU communication, it consumes very little energy and enables fast measurement, ideal for CSO (combined sewer overflow in well treatment) applications.
Deadband elimination enables measurement across the entire range up to the sensor, thus preventing costly overfilling. Two-millimeter accuracy enhances operational safety by ensuring precise measurements throughout the application range.
The device is housed in a robust, submersible IP68-rated enclosure constructed from corrosion-resistant PVDF. Commissioning is straightforward thanks to the Bluetooth interface and the Sitrans IQ App mobile application or the Sitrans RD150 remote display. Even when connected to remote units such as the Sitrans RTU3030C, critical data can be transmitted and remote servicing performed.
