Ultrasonic sensor
E4PA-LS50-M1
60mm ~ 500mm
The remaining quantity of soup is monitored.
The soup level is measured with an ultrasonic displacement sensor.
The K3GN indicates the remaining quantity of soup on a percentage basis.
Four measurements are averaged for stable indication.
Comparative output 1 is produced as a lower-limit action signal. When the
remaining quantity of soup reaches 20% (lower limit), the "Replenish" indicator
turns on.
