产品描述 The LVU40 series ultrasonic transmitters are advanced ultrasonic level measurement sensors for liquids. These products continue to meet demanding applications. The microprocessor-based circuits provide a temperaturecompensated signal for improved accuracy. All models have the ability to filter false echoes produced by peripheral obstructions. Continuous level measurement can be provided in a range of 0.3 to 18.3 m (1.0 to 60') with several power and programmability options. Point level can also be obtained using a PLC (Industrial Programmable Controller) or one of OMEGA’s CNI process controllers.
