Application Examples

Detection of Dust Exhaust

The change in the density of the dust is detected via the E3SA and 
discriminated by the K3GN.

Monitoring of Tank Pressure

The output of the pressure sensor is processed and the pressure is 
displayed. Remote monitoring of the operation is possible with the 
communications function.

Monitoring of Motor Load Current

If the startup time compensation of the K3GN is enabled, the K3GN 
will not be influenced by the inrush current from starting the motor, 
and no signal will be output from the K3GN.

Monitoring Difference between Two 
Line Speeds

The difference between the two line speeds is calculated by the PLC 
and the result is written via RS-485 to the K3GN where it is 
displayed.

Monitoring the Remaining Quantity of 
Soup

The distance to the surface of the soup is detected with an ultrasonic 
sensor and, based on this distance, the K3GN displays the remaining 
quantity. When the remaining quantity of soup decreases to less than 
20%, the K3GN lights the “Replenish” indicator.
