Scale Factor Calculator for 5 V, 10 V, and 20 mA Modules

The Scale Factors of Slope and Offset are used to convert raw data into engineering units suitable for display. Once slope and offset have been determined for specific sensors, enter the values into DataManager™ Software during configuration process.

To utilize the below calculator, the input and output values of the Sensor/Transducer are required.

Also, in-depth information and examples about scale factors and sensors are available.

The equation to determine slope is as follows:

Slope = Full Scale Range of Sensor/Transducer divided by Full Scale Output Signal of Sensor/Transducer

An Offset may be entered, if required. The equation to determine offset is as follows:

Offset = (Minimum Sensor/Transducer Input Value minus(Slope) multiplied by (Sensor/Transducer Output at Minimum Input Value)

Step 1: Enter Sensor/Transducer Input Ranges
Example: A pressure transducer has a range of 0 to 150 psig. The maximum input range is 150; the minimum input range is 0.	Maximum Input Range:
	Minimum Input Range:

Step 2: Enter Sensor/Transducer Output Signals
Example: The same pressure transducer has an output signal of 1 to 5 volts. The maximum output signal is 5; the minimum output signal is 1.	Maximum Output Signal:
	Minimum Output Signal:
