DP-110
Displacement Sensor
Description
DP-110 Displacement Sensor
DP-110 is an aviation transformer displacement sensor identified by its complete execution marking. Engine documentation identifies DP-110 as a transformer displacement sensor used for guide-vane feedback in an AL-31FP control system. The documented supply is 6 V at 400 Hz; the shaft can rotate 360 degrees while the installed working sector is approximately 30 degrees. The designation must be treated as the primary ordering reference because products from the same family can differ in range, electrical interface, calibration, connector, mounting arrangement or system role. External resemblance is not evidence of interchangeability. Selection should be made from the product passport, the aircraft illustrated parts catalogue and the approved maintenance documentation for the exact installation.

Operating function and signal path
The sensor converts shaft angle into an AC voltage used by the compatible regulator to determine guide-vane position. The unit is a sensing element within a larger aircraft circuit; it is not a complete indicator, controller or protective system by itself. Its output is interpreted by compatible receiving equipment, so supply characteristics, polarity or phase, connector pinout, load and calibration must match the documented configuration. The output follows a transformer characteristic and is installed with a documented angular reserve near the initial position. A general explanation of the underlying measurement class is available in this technical reference. That general reference explains the principle only and does not replace product-specific documentation.
Aircraft and equipment application
DP-110 is documented with KRD-99B equipment in AL-31FP-family engine control; exact aircraft and engine modification require confirmation. Where an aircraft or engine family is named, the statement identifies a documented installation context rather than universal applicability to every modification. The exact equipment set, production series and installed connector must be checked before ordering. Related products in the aviation sensors category are provided for catalogue navigation. The DS-10 card is another same-category reference, but the link does not state that the two units are interchangeable or perform the same function.
Installation and maintenance checks
Before installation, technicians should compare the nameplate, suffix, connector, mounting faces and available acceptance record with the approved requirement. The housing, pressure ports or mechanical input, electrical contacts and sealing features should be inspected without altering calibration. Wiring continuity, insulation and output checks must follow the passport limits for this execution. Do not apply a supply voltage, pressure, acceleration, rotation or test signal taken from a neighbouring model. Storage condition and preservation date should also be reviewed when the unit has remained in stock for an extended period.
After installation, functional testing must be performed as part of the complete aircraft circuit, using approved test equipment and the limits defined by the maintenance manual. A correct bench response alone does not prove that the installation wiring, pneumatic lines, mechanical linkage or receiving unit is serviceable. Any discrepancy should be traced without adjusting sealed elements unless the repair documentation expressly authorises that procedure. The maintenance record should identify the fitted designation and serial number so that later troubleshooting does not confuse adjacent family executions.
Ordering DP-110
An enquiry should state DP-110, the required condition, quantity, aircraft or equipment context and the documentation needed with delivery. If the installed marking is incomplete, provide a clear photograph of the label, connector and mounting arrangement together with the relevant catalogue reference. Aviamisto can compare these identifiers before supply, but final installation approval remains with the operator or maintenance organisation. Technical Details below separates confirmed data from values that still require passport verification. Same-category cross-sells are navigation aids only; they must never be interpreted as approved replacements.
For a traceable quotation, also state whether a new-production unit, preserved stock item or another documented condition is acceptable. Requested acceptance documents, test records and packing requirements should be agreed before order placement.
