Exhaust Gas Temperature (EGT) Indicator

Display measurements for engine exhaust gas temperature (EGT)

  • Library:
  • Aerospace Blockset / Flight Instruments

Description

The EGT Indicator block displays temperature measurements for engine exhaust gas temperature (EGT) in Celsius.

This block displays values using both:

  • A needle on a gauge. A major tick is (Maximum-Minimum)/1,000 degrees, a minor tick is (Maximum-Minimum)/200 degrees Celsius.

  • A numeric indicator. The operating range for the indicator goes from Minimum to Maximum degrees Celsius.

If the value of the signal is under Minimum, the needle displays 5 degrees under the Minimum value, the numeric display shows the Minimum value. If the value exceeds the Maximum value, the needle displays 5 degrees over the maximum tick, and the numeric displays the Maximum value.

Tip

To facilitate understanding and debugging your model, you can modify instrument block connections in your model during normal and accelerator mode simulations.

Parameters

expand all

Connect to signal for display, selected from list of signal names.

To view the data from a signal, select a signal in the model. The signal appears in the Connection table. Select the option button next to the signal you want to display. Click Apply to connect the signal.

The table has a row for the signal connected to the block. If there are no signals selected in the model, or the block is not connected to any signals, the table is empty.

Minimum tick mark value, specified as a finite, real, double, or scalar value, in ft/min.

Dependencies

The Minimum tick value must be less than the Minimum tick value.

Programmatic Use

Block Parameter: Limits
Type: double
Values: vector
Default: [0 1000], where 0 is the minimum value

Specify the maximum tick mark value, specified as a finite, real, double, or scalar value, in ft/min..

Dependencies

The Maximum tick value must be greater than the Maximum tick value.

Programmatic Use

Block Parameter: Limits
Type: double
Values: vector
Default: [0 1000], where 1000 is the maximum value

Ranges of color bands on the outside of the scale, specified as a finite, real, double, or scalar value. Specify the minimum and maximum color range to display on the gauge.

To add a new color, click +. To remove a color, click -.

Programmatic Use

Block Parameter: ScaleColors
Type: n-by-1 struct array
Values: struct array with elements Min, Max, and Color

Block label, displayed at the top or bottom of the block, or hidden.

  • Top

    Show label at the top of the block.

  • Bottom

    Show label at the bottom of the block.

  • Hide

    Do not show the label or instructional text when the block is not connected.

Programmatic Use

Block Parameter: LabelPosition
Type: character vector
Values: 'Top' | 'Bottom' | 'Hide'
Default: 'Top'
