Custom scaled sensor values

Digi Connect Sensor+ reads raw sensor values in milliamps (mA), volts, and pulses. Use the Custom
Scaled settings in Remote Manager to convert raw values for both analog inputs and the digital pulse
counter into meaningful values for your environment, such as when converting 4-20 mA current to
liters or pulses to amp hours.
Refer to the sensor's manufacturer specifications for details about conversion rates and calculations.
Analog input examples
In Remote Manager, both the current loop and voltage input settings use the following fields to
convert current or volts into meaningful values for your environment.
Custom Scaled Sample Unit: Unit of measurement that you are converting to, such as liters,
n
watts, miles per hour, degrees, and so on.
Custom Scaled Sample Value (y1): Point 1 custom value associated as follows:
n
Current loop: 4 mA
l
Voltage: 0 V
l
Custom Scaled Sample Value (y2): Point 2 custom value associated as follows:
n
Current loop: 20 mA
l
Voltage: 10 V
l
Use the manufacturer specifications for your sensor to calculate the y1 and y2 values.
4-20 mA current loop input example
This example demonstrates how to determine y1 and y2 in liters for a 4-20 mA current loop input. This
graph is similar to what you find in sensor manufacturer's specifications.
Note When calculating values, there must be a linear relationship between y1 and y2. If the sensor's
measurements are not linear, the calculated values will not be accurate.
The following image shows you enter this information in Remote Manager.
