With its Teflon-coated surface, the sensor is outstandingly suited for usewith corrosive liquids. The masking of fixed objects permits the sensor to bedeployed in locations in which struts or other internal structures extend into themeasuring field.Sensors of the LUC4 series feature a 4 mA ... 20 mA current and 0 V ... 10 Vvoltage output as standard. The outputs have fail-safe behaviour in the event of afault.The ultrasonic converter sends out an acoustic pulse. This pulse is reflected by thecontents of the container and registered by the converter after traveling themeasuring distance. A microprocessor evaluates the echo signals and determinesthe fill level.Sources of interference such as weld seams, fixed installations, etc. aresuppressed reliably via the masking of fixed objects. Changes of the ultrasonicspeed caused by changing temperatures are compensated.Electrical connectionConnector V1541352U1 (BN)4 (BK) 4 mA ... 20 mA2 (WH) 0 V ... 10 V3 (BU)5 (GY)+U B- U BNCCore colours in accordance with EN 60947-5-2.Subject to reasonable modifications due to technical advances.Copyright Pepperl+Fuchs, Printed in GermanyPepperl+Fuchs Group • Tel.: Germany +49-621-776-0 • USA +1-330-4253555 • Singapore +65-67-799091 • Internet www.pepperl-fuchs.com 1
