DUS-1

DUS-1 angular rate sensor

DUS-1 is a gyroscopic angular rate sensor intended to convert rotation about its sensitive axis into an electrical signal for an aircraft or special-purpose control system. The unit belongs to the DUS family of rate sensors, but the suffix is part of the exact designation and must be retained when ordering. Published catalogue data additionally identifies resolution not worse than 0.1°/s, a conversion factor of 13 ±2 mV per degree per second, supply from ±11 to ±15.5 V, dimensions 30 × 30 × 50 mm and mass not over 100 g. The device should be selected by the full marking, connector and installation documentation, not by external similarity. Other DUS-family instruments may share a general operating principle while differing in measuring range, transfer characteristic, electrical interface, mounting orientation or calibration.

Operating function and signal use

During operation, the sensing element responds to angular motion and produces an output used by the connected control, stabilization or measuring circuit. The verified measuring-range statement for this execution is up to 600°/s. The exact polarity, scale factor, zero position and permissible error must match the product passport and the documentation of the receiving equipment. A related item shown through an internal link or cross-sell is provided only for catalogue navigation; it does not indicate interchangeability. For a general explanation of the physical principle, see the rate gyro reference.

Identification and system compatibility

The complete designation DUS-1 is the primary identifier for this card. Search and procurement records may omit hyphens, change letter case or transliterate the original Cyrillic marking, so the accepted alternatives are listed in Technical Details. Aircraft type and installation position are not assigned unless they are confirmed by an illustrated parts catalogue, maintenance manual or passport. The sensor may form part of an automatic control or stabilization loop, but a shared family name alone is not evidence that it is approved for a particular aircraft. Review other verified instruments in the Sensors category.

Inspection before installation

Before installation, inspect the housing, mounting surfaces, connector, locking features and legibility of the full designation. Confirm that the electrical circuit is isolated and that the unit has been stored and transported in accordance with its documentation. Test equipment, supply conditions and acceptance limits must be taken from the passport or approved maintenance instructions for the exact execution. Do not apply values from a similar DUS model merely because the housing is comparable. Calibration, zero-offset checks and polarity verification should be performed using the prescribed bench procedure and compatible harness. Installation orientation and fastening torque also require confirmation from the applicable technical documentation.

Ordering DUS-1

An enquiry for DUS-1 should state the complete part number, required condition, quantity, required documentation and the aircraft or equipment reference in which the unit will be installed. If available, include a photograph of the original marking plate or the removed unit so that the suffix and connector execution can be checked. Aviamisto can review the request against the supplied documentation and identify the appropriate delivery configuration. Another catalogue example is the DChV-2500 speed sensor; it is a different sensor type and is linked only to help navigate the same product category.

For acceptance planning, the request should also clarify whether an individual sensor, a matched set, an inspection record or a specific preservation status is required. Where a certificate or passport is mandatory, its availability must be confirmed before shipment rather than inferred from a catalogue image. Incoming inspection should compare the delivered designation, serial marking, connector layout and mounting features with the approved requirement. Any difference should be resolved before the unit is connected to a test bench or installed. These steps are especially important for legacy instruments whose similar housings can cover several electrical executions and whose published commercial listings may omit essential suffixes.
