Gain Calculator

Choose the Offset

     One direction:  Offset = 0.2V

     Bi-directional:  Offset = 2.5V

Choose the Gain

1. Find the sensor's full scale output ratio  (Ex. 2.00mV/V at 1000lb). Usually

     printed on the load cell, or on the calibration sheet.

2. This means that when 1000lb is applied, the sensor will output 2.00mV     
    (0.002 V) for every Volt that is supplied for excitation.

3. Since the Techmor SG-1 excites with 5V, the full scale output will be
     2mV/V x 5V = 10mV.

4. Choose the desired output range,  0.2V to 4.8V is good for 0-5V systems

     So the amplifier output range is 4.6V.

5.  Divide the desired amplifier output range by the sensor full scale output.

    Gain =  4.6V / 10mV = 460

6.  If the sensor is bi-directional, divide this by 2 because it needs to go both

     directions from 2.5V.  Gain = 460/2 = 230
