Ultrasonic Level Instrument LU90 The LU90 transmitter is an electronic equipment based on the transmission of ultrasonic waves to measure the distance to a liquid or solid in a vessel. The electronic circuit offers the following features: • Emission and reception circuits for the ultrasonic signals, and microprocessor treatment. • Alarm outputs with programmable hysteresis level. • Programmable current output proportional to the distance or level. • HART TM protocol compatibility (model LU90H). Specifications: Measuring range: 0.2 m … 6 m (solids until 3.5 m) Power supply: 18 ... 30 VDC. Power consumption: ≤ 1.5 W Analog output: 4-20 mA. Active or passive. Error of measure signals: 3.6 mA and 22 mA Alarm outputs:Two opto-isolated: Vmax: 30 VDC. Imax: 30mA. Measuring indication: Nº of digits: 4 (1 integer and 3 decimals)Digit size: 7 mm Protection rating: IP67 Ambient temperature range: -40 ..+70 ºC (display only to 60 C) Maximum working pressure: 200 kPa (2 bar) Resolution: 1 mm Precision: ± 2 mm from 0.2 to 2m< 0,25% of measuring range from 2 to 6 m Repeatability: < 0,25% of measuring range 1060 S.
