- Sensor function
analog
The analog output can be set through RS485, and the ultrasonic water level sensor can work in 8 modes. The specific reference is as follows:
Step 1: Connect to the host computer through serial port debugging assistant or modus debugging assistant.
Step 2, set a near point reference distance point.
Step 3, Set a far point reference point
Step 4, set the output voltage or current of the near-point reference point.
Step 5, set the output voltage or current of the far point reference point.
Step 6, set the analog output to switch characteristic selection.
Step 7, set the analog output as linear output or switch output option.
Step 8, reset the sensor to make the new parameters take effect.
8 working modes of the KUS630 ultrasonic water level sensor.
1: Open window mode by default
2: Windowed mode is turned off by default
3: Single-point mode is turned on by default
4: Single-point mode is turned off by default
5: Single-point hysteresis mode is turned on by default
6: The single-point hysteresis mode is turned off by default
7: The presence or absence of detection mode is turned on by default
8: The presence or absence of detection mode is turned off by default
485 output data
485 output data is in MODBUS-RTU format. Refer to the software instruction manual for details.
