Ultrasonic level sensor i

for liquids4-20 mA2-wire

Ultrasonic sensors with integrated transmitter for measurement of distance, level, empty space or volumes. Suitable for harsh ambient conditions. -Sensor as independent, comfortable level measurement -Pre-programmed measurement range steps of 3, 6, 10 and 15 m -Ideally suitable for battery operation through quick measurement times -Resistant to humidity, aggressive environments and heavy temperature fluctuations -IP68 protection -Can be directly connected to PLC -Saves time and space, no transmitter installation needed -DATEM - digital echo processing with automatic false echo avoidance -Ex-approval according to ATEX for Zone 1; optional for Zone 0 -Easy wiring directly to terminal unit in Ex-areas (no Zener barrier required) i-Series level sensors can be used to measure distance, level, empty space or volumes of liquids in any application where highly accurate level measurements are required. The level sensors are designed for use in poor ambient conditions. Soiling as well as wear and tear is avoided thanks to non-contacting measurement. Since transmitter and sensor share the same fully encapsulated enclosure the unit can be easily installed with low space requirements. Extensive programming works are not needed through pre-programmed measurement range steps. The sensors can be directly connected to any PLC, NIVUS GPRS data logger and all systems processing measurement values featuring an active mA-input.
