Development of “Wireless and Telemetry-based Temperature & Strain Measurement system”
Wireless Temperature & Strain measurement system is required to monitor Bearing Health during operation when both the races of Bearing are rotating (at different rpm)
a) Bearing Inner Race speed: 16500 rpm
b) Bearing Outer Race speed: 24500 rpm
c) Preferable location to measure Temperature / Strain: Inner Race
d) Preferable Radial Height: 35 mm
e) Envelop (outside which measurement need to be sensed): F700 mm
f) Sensor to be etched / sticked on target component and signal to be transmitted to a receiver [mounted outside engine casing (static part)]
g) Max. Temperature Sensor needs to sustain during assembly: 190 ˚C for 45 minutes (heating in oil bath)
h) Max. Temperature Sensor has to read during operation: 200 ˚C
i) Max. Static Temperature Sensor has to read: 300 ˚C
j) Temperature in vicinity: 150 ˚C (approx.)
k) Environment (where Sensor to be mounted) is expected to be submerged in Oil (OX27 / OX35) during operation
