Sensor for continuous level monitoring in almost all liquids

July 27th, 2012, Published in Articles: Vector

Ifm Electronic’s efector gwr operates to the principle of guided wave radar and measures the level using electromagnetic pulses in the nanosecond range. The sensor is suited to continuous level monitoring in almost all liquids including aqueous media, coolants, cleaning agents and oils. Efector gwr offers high flexibility due to its modular sensor system. Versions are available with two or four switching outputs or a 4 – 20 mA / 0 – 10 V analogue output.  Easy operation is assured via the user menu and direct indication of the current level is indicated on the LED display. Sensor lengths are available up to 160 cm. The sensor is directly mounted in the tank using a process connection or flange plate. If necessary, the sensor rod can be easily shortened and adapted to the tank by the user. Settings of all parameters as well as programming of the switch points and indication of the current level are carried out via a four-digit alphanumeric display. In addition, the sensor can also be configured, documented and the data record stored via IO-Link or the USB interface E30396.
