Description
Capacitive Level Sensor NR160 is designed to monitor liquids andpowders with high relative dielectric constant
ε
r . With MIN/MAXselector 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
● max. medium temperature +130 C
● min/max selector switch
NR160-...
● transistor output
● recommended for granules, powder, water and other electricallyconductive media
