11 October 2006 -- ifm electronic has developed a new level sensor, the LR, as world's first compact level sensor with guided wave radar (GWR) technology for small tanks. The GWR technology employed in the LR family makes it perfect for continuous level monitoring on plant applications such as coolant areas and parts cleaning machines, where water-based solutions are found. The LR has up to four programmable switch points (including set and reset points) with hysteresis and window functions.
Unlike float switches and vibration forks, with the LR resistance to foam and build up, there will be no need to worry about routine cleaning intervals and unforeseen standstills anymore - a real cost saving benefit! LR comes with a very simple and compact design in which the sensor can be directly mounted in the tank by only using a G3/4 process connection or flange plate with the rod of only 8mm in diameter.
When necessary, the stainless steel rod can also be easily shortened to suit the application.
There are three different lengths to choose from - 240, 450, and 700mm with a very short inactive range of 10/40mm.
Comparing LR with other GWR sensors in the market, it is a real price/performance winner!
