Question

What is linear hysteresis?

Answer

An ideal line is drawn along the output current (or voltage) values for zero pressure and rated pressure to find the amount of error between the actual measured current (or voltage) and the ideal current (or voltage). The linear hysteresis is the maximum absolute value of the difference between the values obtained for pressure rising error and pressure falling error expressed as a percentage of full scale.

Example: The hysteresis for the E8M-10 Pressure Sensor is ±1% F.S.

Converted to voltage,

±1% × 1⁄100 (%) × 4 V (F.S.) = ±0.04 V
