Pressure Sensors Technical Terminology

This is what can be used to activate the pressure sensor.
(The Panasonic Electric Works pressure sensor can be used with gas.)

The pressure value up to which the specifications of the pressure sensor are guaranteed.

The maximum pressure that can be applied to the pressure sensor, after which, when the pressure is returned to below the rated pressure range, the specifications of the pressure sensor are guaranteed.

The temperature range across which the specification values of the pressure sensor are guaranteed.

The supply current required to drive a pressure sensor.

The difference between the rated output voltage and the offset voltage. The output span voltage is also called the full-scale voltage (FS). 7. Offset voltage

The output voltage of a pressure sensor when no pressure is applied.

Output voltage when rated pressure is applied.

When the pressure is varied from no load to the rated pressure, the linearity is the amount of shift between the straight line that joins the no-load voltage value and the rated pressure voltage value (expressed as the ratio of the amount of shift (D1) at half of the rated pressure value with respect to the full scale voltage (FS)).

The ratio of the difference (D2) in the no-load output voltages when the pressure is varied from no load to the rated pressure then reduced back to no load, with respect to the full scale voltage (FS).

The variation of the offset voltage with changes in ambient temperature. The difference between the offset voltage at the standard temperature and the offset values at the compensation lower limit temperature (low temperature) (lambda1) and compensation upper limit temperature (high temperature) (lambda2) are obtained, and the offset voltage temperature characteristic is expressed as the ratio of the larger of these two differences (absolute) with respect to the full scale voltage (FS).

The variation of the sensitivity with changes in ambient temperature (variation in full scale (FS)). The difference between the full scale voltage at the standard temperature (FS) and the full scale values at the compensation lower limit temperature (low temperature) (FS1) and compensation upper limit temperature (high temperature) (FS2) are obtained, and the offset voltage temperature characteristic is expressed as the ratio of the larger of these two differences (FS1 - FS and FS2 - FS (absolute)) with respect to the full scale voltage (FS).

Refers to the resistance value of a piezoresistance formed on a monolithic silicon substrate.
For example, the values of the resistances R1 to R4 in the bridge are typically 5kohm each.
When the resistances of the resistive elements R1 to R4 that comprise the bridge are 5kohm each, the equivalent composite resistance of the bridge is 5kohm (3kohm bridges are also available).

Accuracy of offset voltage and rated pressure output voltage within the temperature compensation range.
