3. Default Settings / Factory Default Values
| Name | For Communication Protocol | Description | Unit | Default Value |
|---|---|---|---|---|
| Measurement Interval | All | Specifies the period during which measurement values are recorded . 10 minutes means that every 10 minutes the sensor takes a measurement. | min | 5 |
| Delta Value | All | Specifies the absolute change in the measured value compared to the last transmission that must occur for an alarm transmission to be triggered. This transmission is carried out regardless of the regular transmission interval. Always refers to the main measured value. | mbar | 100 |
| Regular Transmission Interval | All | Number of measurements after which the sensor sends an uplink even if no alarm condition exists. | Number | 2 |
| Low Temperature Warning | All | Threshold value in °C at which an alarm message is triggered due to a temperature that is too low. | °C | 4 |
| High Temperature Warning | All | Threshold value in °C at which an alarm message is triggered due to a temperature that is too high (first high temperature threshold). | °C | 55 |
| Critical Temperature Warning | All | Threshold value in °C at which an alarm is triggered due to a critical, excessively high temperature (second high-temperature threshold). | °C | 55 |
| Low Pressure Warning | All | Threshold value in mbar at which an alarm is triggered due to pressure that is too low. | mbar | 8000 |
| High Pressure Warning | All | Threshold value in mbar at which an alarm is triggered due to excessive pressure (first high-pressure threshold). | mbar | 200 |
| Critical Pressure Warning | All | Threshold value in mbar at which an alarm is triggered due to critical, excessively high pressure (second high-pressure threshold). | mbar | 8000 |
