LV850 LEVEL SENSOR
1 Description
Level Sensor LV850 is suitable for liquids with low relative dielectric constant
ε
r
(e.g. oil). Units come with Minimum and Maximum selector switch.
It operates on the principle of electrical capacitance changes arising when an
electrode surrounded by air is immersed in the medium.
• LED status display
• Selection of minimum and maximum function by changeover switch.
Minimum switching
Normally the sensor is immersed and the green LED indicates. As the level
drops below the sensor the green LED extinguishes.
Maximum switching
Normally the sensor is not immersed and the green LED indicates. As the
level rises above the sensor the green LED extinguishes.
• In the event of a short-circuit in the load circuit, the green LED will
extinguish and the red LED will flash.
