Long term stability9
1
Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.
2
Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.
3
The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.
4
Operating temperature range: The temperature range over which the sensor will produce an output proportional to force.
5
Compensated temperature range: The temperature range over which the sensor will produce an output proportional to force within the specified
performance limits.
6
Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the force range at 25°C [77°F].
Includes all errors due to force non-linearity, force hysteresis, and non-repeatability.
7
Full Scale Span (FSS): The algebraic difference between the output voltage at full scale force and the output at zero force.
8
Total Error Band (TEB): Combined error from calibration, accuracy and temperature effects over the compensated temperature range at 5.0 V from
15 %FSS to 95 %FSS.
9
Long-term stability after 1000 hr of operation at 25°C [77°F].
