TDR level sensor Sick LFP0900-A4NMB (1057080)

Level sensors
TDR level sensor   Model Name LFP0900-A4NMB Part No. 1057080   Самое главное No mechanical moving parts Manually cutable and exchangeable monoprobe with lengths from 200 mm up to 2,000 mm Immune to deposit formation Process temperature up to 100 °C- process pressure up to 10 bar Small inactive areas, ideal for small containers Accurate measurement, even when liquid type changes 3-in-1: combined display, analog output (acc. NAMUR NE 43) and binary output High enclosure rating of IP 67, rotatable housing Преимущества Rugged design increases service life High flexibility due to cutable and exchangable monoprobe Cost savings due to multiple output signals: one system for both level detection and continuous level monitoring Time and cost savings due to low maintenance and quick commissioning No calibration or recalibration required for commissioning, thus saving time and costs Compact and rotatable housing ensures flexible installation No crosstalk when several sensors are mounted next to each other Advanced technology enables adjustment-free measurement of oil- and water-based liquids
