Pressure sensors

C32 series

Absolute pressure sensor die

Preliminary data

α_sand β_sare the linear and nonlinear temperature coefficient of the sensitivity respectively (see ¹⁵⁾).

Therefore TCV₀⁺and TCV₀^–are defined for the measurement temperature range by:

V_o(T_min) − V_o(25°C)

T_min− 25°C

V_o(T_max) − V_o(25°C)

T_max− 25°C

Full scale value FS

Sensitivity S

The sensitivity is defined for a bridge voltage power supply V_DD= 5 V. It can be determined by the formula:

FS = V_out(p_rmax) − V_o

V_out(p_rmax) − V_o

S =

p_rmax

This parameter is tested for process control on samples, mounted on a TO39 base.

14)

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_x= p_rmax/2. The nonlinearity is defined at p_x= p_rmax/2,

using the equation:

V_out(p_x) − V_o

p_x

L =

−

V_out(p_rmax) − V_op_rmax

This parameter is tested for process control on samples, mounted on a TO39 base.

Temperature coefficient of sensitivity α_Sand β_S:

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_meas,_min= –20 °C to T_meas,_max= 80 °C with T_R= 25 °C.

The temperature coefficients of first and second order are defined with the polynomial:

The coefficients α_Sand β_Sare calculated using the three measurement points of S(T) at T_meas,min, T_Rand T_meas,max

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_{r, min}, p₁, p₂, p₃, p_r,max, p₃, p₂, p₁, p_{r, min}

V_out,2(p_k)− V_out,1(p_k)

pHys =

With k = min, 1, 2, 3, max. The pressure steps are: p_rmin= 0, p₁= 0.25·p_r,max, p₂= 0.5·p_r,max, p₃= 0.75·p_{r, max}, p_r,max

This parameter is tested for design verification on samples, mounted on a TO39 base.

Reliability data

For long-term stability of offset voltage LTSV₀please refer to the defined Aktiv Sensor’s standard AS100001 in chapter

“Reliability data” on the internet.
