Description
Retained product information
P-109 aircraft resistance temperature sensor P-109, including P-109M1 and P-109M4 modifications, is an aircraft resistance temperature sensor used to measure temperature of non-aggressive liquid and gaseous media. The sensor converts changes in medium temperature into electrical resistance signals for aircraft monitoring and control systems. It can be used with air, fuel, oil and other approved working media depending on the installation and system documentation. Function of the P-109 temperature receiver The main function of P-109 is temperature measurement in aircraft systems and transmission of temperature data to onboard equipment. The unit works as a resistance thermometer: the sensing element changes its resistance according to the temperature of the surrounding medium. The resulting electrical signal is used by control, indication or monitoring systems for thermal regulation, engine protection, air-system control or fuel and oil temperature correction. P-109 sensor construction P-109 is a two-channel temperature sensor with two independent electrical circuits. The source context describes its sensing element as a platinum resistance element with a 100P characteristic according to GOST. The internal structure includes an insulated tubular frame with bifilar winding of platinum wire inside a sealed protective metal housing. The design is non-disassemblable and intended for direct installation into aircraft pipelines, ducts or controlled equipment cavities. Installation areas of the P-109 sensor The P-109 temperature receiver is installed inside aircraft systems and fluid / gas lines. Typical installation areas include engine oil systems, gearbox oil systems, fuel lines, air-conditioning ducts and anti-icing air ducts. The working immersion part is placed directly into the controlled medium, while the body is fixed through a threaded connection and sealed with a gasket. The unit may also be installed on test benches or special ground equipment when the same temperature-control principle is required. Examples of P-109 aircraft application The source context links P-109 and its modifications with several Soviet and Russian aircraft systems. Examples include Tu-154M APU compartment heating and temperature-control systems, Il-76 / Il-86 / Il-96 tail-section and air-system monitoring, PS-90A engine oil temperature monitoring on Il-96-300, Tu-204 and Tu-214, MiG-31 fuel temperature monitoring during refueling, and Mi-8 / An-148 air-conditioning or anti-icing systems. Actual installation point depends on the aircraft modification and maintenance documentation. Ordering and replacement of P-109 When ordering P-109, the buyer should specify the exact modification, such as P-109M1, P-109M2 or P-109M4, as well as the aircraft type, medium, temperature range and mounting interface. Since similar temperature sensors may differ by resistance characteristic, immersion length, connector or cable arrangement, replacement must be checked against the aircraft or engine documentation. Product passport, calibration data, test report, storage records and condition should be confirmed before supply.
P-109: purpose and identification
P-109 is a Temperature Sensor that converts the temperature of the monitored medium into a signal for the associated instrument or system. The exact execution is determined by the complete marking, series and documentation. A similar housing, common opening characters or a related function does not establish matching ratings.
This category contains different equipment classes: temperature receivers, thermometers, air- and liquid-pressure receivers, regulators and individual measurement units. The actual function of the item is therefore more important than the broad category name. Read the designation with every letter, digit, hyphen, version and series reference preserved.
Function in the measurement system
The item converts the temperature of the monitored medium into a signal for the associated instrument or system. It is not necessarily a stand-alone indicator; depending on the design, it may operate with a remote indicator, regulator, pressure line or measurement set. The applicable documentation defines the circuit, medium, supply, range and connection arrangement.
For a temperature item, confirm the sensing principle, monitored medium, range and compatible indicator. For a pressure receiver, also confirm pressure type, channel count, ports, heating, drainage and connected lines. An RF measurement receiver must be selected by its own radio-frequency data rather than by requirements intended for an aircraft pressure or temperature sensor.
Selection by designation
Before ordering, compare the primary and alternative designations, execution, range, output, electrical supply, connector or ports, mounting, dimensions and mass whenever documented. Numerical values in Technical Details are retained from the previous card or a supporting source and must be checked against the passport for the actual unit.
Related modifications may differ in channel count, resistance, calibration, working medium, measurement limit, heater voltage or mounting interface. Do not treat them as interchangeable without an explicit documentary reference. General technical background is available under Temperature Sensor.
Pre-installation inspection
Incoming inspection includes checking the marking and documentation and examining the housing, sensing element, connector, pressure ports, drainage holes, mounting points and seals as applicable. Reject or investigate cracks, deformation, corrosion, contaminated passages and damaged contacts. Test the unit under the approved procedure for the exact execution.
After installation, check line tightness or electrical continuity, routing of pressure lines and wiring, and then perform the prescribed functional test. External integrity alone does not establish measurement accuracy. Assign an aircraft application only when supported by a passport, illustrated parts catalogue or maintenance document.
Related catalogue positions
Functionally related products include P-102 / P102-MS-400, P-125, P-77 Version 2, P-125-1. They are grouped by measurement function for navigation and do not imply interchangeability. More items are listed in the Pressure & Temperature Sensors category.
Enquiry information
An enquiry for P-109 should state the complete designation, quantity, required condition, marking photograph, delivery scope and required documents. When available, identify the associated indicator, regulator or system. Price, actual availability, condition, lead time and documentation are confirmed separately for the offered unit.
