Description
Level Sensor NR150 is suitable for liquids with low relative dielectricconstant
ε
r (e. g. oil). With MIN/MAX selector switch.The functions for MIN or MAX monitoring as well as other properties(output signal LSS or HSS, response delay etc.) are factory pre-set.
The switch point is adjustable by means of a teach-in momentary
switch.
Features
● status indication by 2 LEDs
