Part Number:TMP117
Hello everyone.
My company is designing a wireless temperature sensor for industrial fridges and cold chambers. The product is sealed inside a small enclosure and runs on battery for 5 years. We are using TMP117 as the temperature sensor.
The client is asking us about temperature measurement stability and drift over these 5 years of expected product life. Bear in mind the product will run in three different temperature ranges: around -18°C, 6°C and 20°C.
The datasheet states that a drift of ±0.03°C is observed when submitting the part to 300 hours at 150°C (acceelrated aging). How can I extrapolate this data to find the expected (or maximum value) temperature measurement drift over 5 years? Can I assume that the sensor will drift ±0.03°C per year? Is this drift linear over the years?
Thank you very much.
