Level sensor suitable for most applications

Automatic self-adjustment to suit almost any medium, including oils and wastewater, is a key benefit of the new LK electronic level sensors from IFM Electronic. For users, this means that just one type of level sensor can be used for virtually every application, making installation straightforward and eliminating the need to tie up money in large stocks of spares.
LK level sensors automatically compensate for the build-up of contaminants on the sensing surface. This results in virtually unlimited working lives without routine maintenance or cleaning, providing further savings for users.
Ideal for applications involving any kind of liquid, the sensors are available with probe lengths of 264, 472 and 728 mm. All types incorporate a three-digit seven-segment display, which provides an instant readout of level. A programmable offset allows the reading to be adjusted to allow for the height of the probe above the base of a tank.
There are two switching points provided, each with adjustable hysteresis, which means that single LK sensors can, in many applications, replace up to four conventional level switches. Switching points are easily adjusted by means of a simple pushbutton system and all settings are immediately confirmed by the seven-segment display.
These sensors are designed for operation from DC supplies in the range 10 to 32 V. The units have two outputs which are provided with short-circuit, overload and reverse polarity protection, and which are rated at 200 mA. They have an IP76 III protection rating and can be used with media having temperatures from 0 to 80°C.
