D-1M U2 Engine Rotational Speed Sensor

D-1M U2 Engine Rotational Speed Sensor

TMi Magneto-Induction Tachometer with D1M, D1MM, D2M & D2MM Sensors The TMi magneto-induction tachometer is designed for continuous remote measurement of rotational speed (RPM) in aircraft engines, gearboxes and other rotating mechanical assemblies. The system consists of a TMi indicator and one of the compatible primary sensors: D1M, D1MM, D2M or D2MM. The D1M and D1MM sensors operate with a single indicator, while the D2M and D2MM sensors are designed to simultaneously drive two indicators. All sensors and indicators of the same type are fully interchangeable, allowing easy replacement and maintenance. Built for demanding aviation and industrial applications, the TMi tachometer provides precise RPM indication, excellent reliability and long service life under harsh environmental conditions. Key Features • Continuous remote RPM measurement • Compatible with D1M, D1MM, D2M and D2MM sensors • High measurement accuracy of ±1% within the operating range • D2M and D2MM support two indicator units simultaneously • Fully interchangeable sensors and indicators of the same type • Separate supply of sensors and indicators available • Three-lug flange mounting for secure installation • Suitable for aviation, aerospace and industrial equipment • Reliable operation in severe environmental conditions Technical Specifications Measurement Accuracy ±1% within the operating range ±1.5% outside the operating range (remaining scale) Operating Temperature Primary Sensors U2 version: -60°C to +80°C T2 version: -20°C to +80°C Indicator Unit U2 version: -50°C to +50°C T2 version: -20°C to +50°C Relative Humidity Up to 80% Maximum Cable Length Up to 50 meters between sensor and indicator Weight Indicator: 0.55 kg Primary sensor: 0.90 kg Applications The TMi tachometer system is widely used in: Aircraft engines Helicopter transmission systems Aviation gearboxes Turbine equipment Industrial rotating machinery Test benches and maintenance facilities Compatible Components D1M Primary Sensor D1MM Primary Sensor D2M Primary Sensor D2MM Primary Sensor TMi Indicator
