IFM has introduced a guided-wave level probe for oil or water that is said to detect more fluids and ignore residues of foam or sticky material that might build up on the probe and give a false level.

The solid-state principle avoids mechanical issues with floats that stick.

The three new versions of the sensor can be used in aqueous media, coolants and cleaning solutions or oils, making them suitable for the continuous level monitoring of almost all liquids.

IFM offers the Efector GWR with two or four switching outputs, or with switching and analogue output.

The modular sensor system consists of the sensing head, the probe and, optionally, the coaxial tube.

Microwave pulses are transmitted by the sensor head and guided along the probe.

If the microwave pulse hits the medium, it is reflected and evaluated by the sensor.

The sensor is installed in the tank using a process connection or flange.

The user can shorten the probes and adapt them individually between 100 and 1,600mm.

The coaxial tube is required for the unit to function correctly in low dielectric media.

Setting is done via a simple parameter menu and an electronic lock is fitted to prevent tampering.

The four-digit alphanumeric display permanently shows the current level.

The LR series gwr level sensors operate on a 18 to 30V DC supply using industry-standard M12 connectors.

The IP rating of 67 means that they will not be affected by spillage in the tank area.
