Passive Sensor Output Voltage Calculator
Active Sensor Output Calculator
Sensor applications are complicated systems. Key application elements including Target, Sensor, Load and Cable details all affect system performance. This calculator helps to estimate the output behavior of the system. Calculated output data is intended to raise confidence of the proposed system design. It should be considered a starting point but cannot consider all variables due to unknown factors in your specific system.
