LMT70: temperature sensor failures - fast temperatur cycling - lifetime

Part Number: LMT70

Hello,

 

we have trouble with the LMT70 temp. sensor.

 

Task:

We want to measure the temperature of our heating process. The sensor is fixed on an aluminum heating plate, which rotates (3000rpm)

Heating takes place within 5 seconds from 60°C to 105°C

Cooling down within 10 seconds from 105°C to 60°C.

In total we cycle between 20°C and 110°C in a short time.

 

Goal:
The goal should be that the sensors measures 1,000,000 (1 million) temperature changes for our control purposes.

 

Description failures:
Currently the sensors drop at approx. 30,000 temperature changes.

 

Question:
- is the LMT70YFQT basically suitable for this application?
- what could be the reasons for the failure?
- Are there alternative ICs which can handle this?

Many thanks in advance.
