miniDaqu — Manual 9.6 Trim, Flap And Other Position Sensors
ˆ
flap position,
ˆ
throttle position,
ˆ
and some others.
These sensors are usually potentiometers (variable resistors) with different
ranges. Daqu supports ranges of 400 Ω, 5 kΩ and 10 kΩ.
A potentiometer can be connected as variable resistor or variable voltage.
Refer to the potentiometer datasheet for pin identification.
Connection schematics for both cases are given in section 3.6 starting on page
19. Here, configurations are shown for both cases.
9.6.1 Variable Resistance
Figure 8 shows typical schematics for the variable resistance. The correspond-
ing channel is configured something like shown by Table 16.
Option Selection/Setting
Channel Any E or F
Function Pitch trim
Sensor Res 400 Ohm / 5 kOhm / 10 kOhm
Report time 0.2 – 0.5 s
Filter about 0.5 s
Table 16: An example configuration for pitch trim resistive sensors.
Similar configuration can be used for flaps, various positions and other trim
functions.
9.6.2 Variable Voltage Divider
Figure 9 shows typical schematics for the variable voltage divider. The cor-
responding channel is configured something like shown by Table 17.
9.6.3 Min/Max Values
Once sensors are properly connected and configured, their stopping limits
must be determined – their minimal and maximal values must be entered
into the system.
