TUE-48

Retained product information

TUE-48 electric thermometer for remote temperature measurement TUE-48 is a universal electric thermometer designed for remote measurement of working fluid and air temperatures. The instrument is used in aviation, armored vehicles, special-purpose equipment and other transport systems where temperature must be indicated at a distance from the sensing point. In aircraft applications, it can be used for oil temperature, coolant temperature or carburetor air temperature monitoring, depending on the installed receiver and system configuration. Temperature indication through TUE-48 The thermometer operates with a remote temperature receiver installed at the measurement point. As the temperature changes, the resistance of the heat-sensitive element in the receiver changes. The TUE-48 measuring instrument responds to this resistance change and displays the corresponding temperature value on the scale. The system is not based on a thermocouple signal. It uses a magnetoelectric ratiometer principle, which makes correct matching between the indicator and receiver important for accurate indication. TUE-48 with P-1 and P-1V temperature receivers A standard TUE-48 set usually includes one cockpit or panel indicator and one temperature receiver, such as P-1 or P-1V. The receiver is installed in the controlled medium, while the indicator is mounted on the instrument panel or equipment panel. The receiver and indicator must correspond to the same measuring range and electrical characteristic. If the indication is incorrect, the check should include the receiver, indicator, wiring, connector, supply voltage and grounding. Application of TUE-48 in aviation and transport equipment TUE-48 is used in aircraft and other vehicles where liquid or air temperature must be monitored remotely. In aviation applications, it may be installed in engine oil systems, cooling circuits or air intake / carburetor temperature control circuits, depending on the aircraft configuration. Exact applicability depends on the aircraft type, engine system and installed receiver. Similar thermometers may differ by measuring range, receiver type, scale marking or technical specification, so replacement should be confirmed by documentation. Identification and ordering of TUE-48 Before ordering, the full designation and set composition should be checked against the product passport, technical specification or equipment documentation. The standard supply set may include the TUE-48 indicator, a P-1 or P-1V receiver, a three-pin plug and passport documentation. Operating manuals and verification procedures may be supplied separately for a batch of instruments. The product is also known under alternative designations TUE-48, TUE-48-T and ТУЭ-48.

TUE-48: purpose and identification

TUE-48 is a Electric Thermometer that provides remote temperature measurement through a compatible receiver and indicator. 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 provides remote temperature measurement through a compatible receiver and indicator. 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 Electric Thermometer.

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.
