Description
DA-11 precision accelerometer
DA-11 is a pendulous, closed-loop accelerometer intended to measure linear acceleration in precision inertial systems. Published technical literature describes a stone-supported pendulum, an angular pickoff and an electromagnetic torque element used in the feedback loop. The measuring range is identified as selectable from ±1 g to ±10 g. This product must not be confused with unrelated DA-11 commercial devices: the aviation context, Cyrillic marking and instrument documentation are essential for identification.
Operating principle and performance
Acceleration displaces the pendulous element, the pickoff detects the displacement and the feedback system applies a restoring torque. The feedback current therefore represents the measured acceleration. Available literature gives a sensitivity threshold of 5 × 10⁻⁶ g, a scale factor of 1.28 ±0.32 mA/g and zero signal within ±0.58 × 10⁻³ g. These are published instrument characteristics, but the actual range execution and calibration must be confirmed by the passport. For background on this instrument class, see the accelerometer reference.
Electrical supply and system role
The cited technical source lists three supply components: 10 V at 12 kHz, 2.5 V at 19.2 kHz and 36 V at 400 Hz. The precise connector, pin assignment, phasing and associated electronics are not inferred from those values and require the approved circuit documentation. DA-11 is described for precision inertial navigation applications, but a specific aircraft type is not assigned without an IPC, equipment manual or passport that names the installation. Other verified units are listed in the Sensors category.
Inspection and installation control
Before installation, verify the DA-11 marking, selected measuring range, connector, mounting datum and sensitive-axis orientation. The cited literature states resistance to 10,000 shock pulses at 25 g with a 25 ms pulse duration; this is not a substitute for checking the condition of an individual stored unit. Use the prescribed test bench and compatible electronics to verify zero, scale factor and direction of response. Do not transfer calibration data from another serial unit. Cleanliness, fastening and thermal stabilization can affect precision measurements and must follow the applicable documentation.
Ordering DA-11
An enquiry should identify the DA-11 aviation accelerometer, required range, condition, quantity, documentation and target equipment reference. A clear photograph of the marking and connector is useful when several devices share the same abbreviated designation. Aviamisto can review the supplied information before proposing a delivery configuration. The DLUK-10 linear acceleration sensor is linked as another sensor-category item and is not presented as interchangeable.
Incoming inspection should compare the full designation, range execution, connector and mounting interface with the approved requirement. Passport and calibration-document availability must be confirmed before shipment when required. The product page summarizes verified public technical data, while installation authority remains with the responsible aviation organization. Any discrepancy between the marking, passport and aircraft documentation must be resolved before powering or testing the unit.
The enquiry should also clarify whether an individual sensor, a matched set or a particular preservation status is required. Catalogue status does not by itself confirm the year of manufacture, calibration validity or documentation package of a specific unit. Those details must be checked against the proposed lot. After receipt, acclimatization, electrical testing and acceptance should follow the approved procedure for precision inertial components.
