If the sensor does not meet any standard characteristics of the available sensors, you can select the Type as Custom Sensor and set its characteristics. There are three type of custom sensor available Current, Voltage and Resistive
|
NOTE
|
To configure custom sensor:
The following table describes the configuration properties and their definitions.
Name |
Definition |
Enable |
Select True to enable the selected custom sensor configuration. |
Sensor Name |
Enter the name of the sensor |
Sensor Type |
Select sensor Input (Current, Voltage and Resistive) from the Sensor Type drop-down menu. |
Sub Type |
Select a sensor type from the Sub Type drop-down menu. |
Specification Unit |
Specification Unit option in the drop-down menu depends upon the Data Type selected while configuring the details on the Add window. |
Linearization |
The Linearization field, where the linearization points are provided to define the characteristics of the sensor. The Tabular Conversion Dialog window is displayed. |
Sensor Low Limit |
Lower limit in the Low Limit field. |
Sensor High Limit |
Upper limit in the High Limit field |
Sensor Reading Output Limits |
Select the value for Sensor Reading Output Limits from the respective drop-down menus. Sensor Readings Outside Limit,
|
Offset |
Offset is the precision limit of the curve |
Validation Text |
This field verifies the configuration of custom sensor, if any of the field not configured it will display a message. |
Figure 9: Tabular Conversion Dialog Window
Enter the low and high limit sensor values in the Sensor Low Limit (Sensor value at 0 mA) and Sensor High Limit (Sensor value at 20mA) fields respectively as per Sensor Data Sheet.
Similarly add and enter value for the sensor resistance value and sensor voltage value for Resistance and Voltage input.
If any of fields not configured, the Validation text will display a message.
Figure 10: Custom Sensor Configuration
Once the custom sensor configured, user can integrate these custom sensor configurations on the UI terminals of the controller.
