PT1000 drifts more than 100°C
I'm using a PT1000 and MAX31865 to measure the temperature inside a machine.
Electronics (MAX31865 and MCU) are inside an isolated box. The PT1000 is outside and connected in two wire configuration (...

How "Zero" is this supposedly Zero-TCR resistor? And how much better is it than this other one?
I found a resistor at Digikey, and the TCR was quoted as being 0.0ppm/°C, and I had to check the datasheet just to refute my suspicion that it was a data entry error, and it looks real, but just how ...

Low frequency asymmetrical led blinking circuit, lacking thermal stability
I'm trying to use a NE555D to achieve a 500ms on, 1500ms off, duty cycle. The exact timing is not that important(+-20%).
But my problem is that when the temperature changes it greatly effects the ...

Voltage reference drift in ppm/°C to V/°C
How does one convert drift in ppm/°C to V/°C?
Assume a 5 V voltage reference has an output voltage drift of 12 ppm/°C.
What is the output voltage drift in volts for a target temperature of 85°C?

IGBT Temperature Drift: How to Achive Stability?
I remember the BJT transistor circuits are designed to compensate for the fact that the parameters of the transistor change with the temperature. I could not find similar ready-to-use solutions for ...

Max31855k - fluctuation and drift
I'm using a b 31855k breakout board (a chinese one at that) with the olimex A20 and a K-type thermocouple (which works OK on another device with the 31855k).
The problem is, that the thermocouple temp ...

Temperature drift on volatge divider built with resistors from the same series
I am in the process of designing a data acquisition device that will be used outdoors, with temperature swings of around 30 degrees.
For this i need to scale the input to a voltage suitable to the adc ...
