DLUK-20

Measurement function and electrical output

The sensor responds to linear acceleration and provides an electrical output for compatible indication, recording or automatic-control equipment. A fixed-base zero-output statement of 0.3–0.5% of range and a sensitivity threshold not over 0.1% of range are listed in the available technical record. The supply is stated as ±15 V, with an additional ±1.5 V value relative to the midpoint in the published listing. Because abbreviated commercial descriptions can omit wiring context, connector pinout and circuit interpretation must be checked against the exact passport. For general background, see the accelerometer reference.

Execution identification and compatibility

The number in DLUK-20 identifies the measuring-range execution and is not an optional catalogue suffix. DLUK-5, DLUK-10 and DLUK-20 are separate range variants and should not be described as interchangeable. Available data gives an operating temperature range from −60 to +60 °C and current consumption not over 45 mA. The published dynamic statement lists a resonance peak in the 1.6–2 range and a 90° phase-shift frequency between 20 and 80 Hz; the exact test interpretation must be taken from the product documentation. Related units are listed in the Sensors category.

Inspection and installation checks

Before installation, verify the full marking, measuring direction, mounting surface, body condition and connector. The sensor orientation is functionally significant because acceleration is measured along the specified axis. Use only the approved harness and bench procedure, and confirm the zero signal on a stable base before applying a calibrated acceleration input. Mounting torque, polarity and grounding must come from the applicable technical documentation. A similar outline or connector does not demonstrate the same range, scale factor or dynamic response. Do not install the sensor when the marking is incomplete or when its calibration status cannot be established.

Ordering DLUK-20

An enquiry should specify DLUK-20, quantity, condition, required documentation and the equipment reference. A photograph of the removed unit or its nameplate helps confirm the exact range suffix. Aviamisto can review the request and clarify the delivery configuration. The DUS-1 angular rate sensor is a different measuring device and is linked only to help navigate the category.

Incoming inspection should compare the delivered designation, body, connector and mounting geometry with the approved requirement. Where a passport, calibration record or preservation statement is mandatory, confirm it before shipment. The technical values in this card are a structured summary of available records, not a replacement for installation instructions. Any difference between the card, the marking and the aircraft documentation must be resolved before electrical connection or bench testing. This approach prevents a range variant from being selected merely because it belongs to the same DLUK family.
