Description

The PS Sensor block represents a generic linear sensor. The block converts the physical signal input U into an electrical output Y across the + and - ports. The Output type parameter value determines which of the following electrical outputs the block produces:

• Output voltage

• Output current

• Output resistance

Y is related to U as Y = max(min(A · U + B,Y_max),Y_min), where Y_min and Y_max are minimum and maximum limits on the output, respectively.

Assumptions and Limitations

The PS Sensor block does not support energy accounting. If you try to get energy information for this block using the getEnergyInfo function, the function generates an error message.

Ports

Input

U — Physical input signal

physical signal

Physical input signal.

Conserving

+ — Positive voltage

electrical

Electrical conserving port associated with the PS sensor positive voltage.

- — Negative voltage

electrical

Electrical conserving port associated with the PS sensor negative voltage.

Parameters

Output type — Sensor output type

Variable voltage (default) | Variable current | Variable resistor

Indicates whether the sensor output is a Variable voltage of Y V, a Variable current of Y A, or Variable resistor with a value of Y Ω.

Sensor gain, A — Output sensitivity

1 (default)

Sensitivity of the output Y with respect to the input U, dY/dU.

Sensor offset, B — Sensor offset

0 (default)

Output when the input U is zero. The output does not exceed the limits Y_max and Y_min.

Maximum output, Ymax — Maximum output

5 (default)

Upper limit on the sensor output. The following table shows the units of this parameter, which depend on the selected value of the Output type parameter.

Output type	Units
Variable voltage	V
Variable current	A
Variable resistor	Ω

Minimum output, Ymin — Minimum output

0.01 (default)

Lower limit on the sensor output. The following table shows the units of this parameter, which depend on the selected value of the Output type parameter.

Output type	Units
Variable voltage	V
Variable current	A
Variable resistor	Ω

If you select Variable resistance for the Output type parameter, the minimum resistance Y_min must be greater than zero.
