Radar level sensor benefits with IO-Link
With IO-Link, the LW free radar sensor can provide:
- Higher measurement resolution than analog without scaling (1mm steps up to 15 m)
- Internal device temperature of the sensor
- Measured power supply voltage
- Current device status and diagnostic information including signal strength (Good, Degraded, Bad) and cleaning required alert
- Automatic device replacement
Data structure and process values
Device status and possible causes
| 0 | Device is OK | Sensor is operating normally |
| 1 | Maintenance required | Cleaning of the sensor face is required |
| 2 | Out of specification | Termperature over / under run, short circuit, check installation |
| 3 | Functional check | Set the parameter [Reference height] |
| 4 | Failure | No reflection signal, parameter error, hardware fault |
