Siemens 西门子 7ML50500AA211DA0 料位控制器

Siemens LUT400 series ultrasonic level controllers. Available in two models, LUT420 for level control of slurries, solids and liquids with basic data logging and pump control functionality, LUT430 for level, pump and flow control. The LUT430 has all the functionality of the LUT420 with the addition of advanced pump control and alarm function. When used with Siemens Echomax transducers the LUT420\/LUT430 utilises Siemens ‘Sonic intelligence’ technology to guard against errors due to false echoes. Suitable for a varied range of applications including level measurement, pump control, open channel , storage vessel and dry storage monitoringHART 7.0 USB communication. 4 to 20 mA output \/ 3 relays. Operational range 0.3m to 60m (transducer application\/dependant). Data logger capability. Echomax compatible. Accuracy of ± 1mm + 0.17% of distance. Digital back-up override from point level sensor.
