Full scale value FS
Sensitivity S
The sensitivity is defined for a bridge voltage power supply V
This parameter is tested for process control on samples, mounted on a TO39 base.
Nonlinearity L
This parameter may be influenced by assembly.
The nonlinearity is measured using the endpoint method. Assuming a characteristic, this can be approximated
by a polynomial of second order, where the maximum is at p
using the equation:
This parameter is tested for process control on samples, mounted on a TO39 base.
Temperature coefficient of sensitivity
These parameters may be influenced by assembly.
The temperature coefficients of sensitivity are tested for design verification on samples, mounted on a TO39 base
over a reduced temperature range T
The temperature coefficients of first and second order are defined with the polynomial:
The coefficients
Pressure hysteresis pHys
The pressure hysteresis is the difference between output voltages at constant pressure and constant temperature while
applying a pressure cycle with pressure steps of p
With k = min, 1, 2, 3, max. The pressure steps are: p
This parameter is tested for design verification on samples, mounted on a TO39 base.
