How it works is simple. It finds the link between heat and a signal pulse. The tool will take a temperature number. Then it will give a frequency number. It uses a known baseline frequency.
It uses a temperature coefficient. It will help you predict sensor output. You can use it for tests, tuning, or checks. It uses a clear formula. It keeps math easy.
When to calculate temperature to frequency?
When an engineer is tuning a sensor, they use this tool. For example, an instructor is showing a class a lab oven. He sets the oven to 150°C. He checks a 1 MHz sensor at 25°C. He wants to know the new frequency. He asks the students to follow. You can see and test it live.
Calculate example step-by-step
First know formula:
f = f0 × (1 + α × (T − T0)).
Second list values:
f0 = 1,000,000 Hz; T0 = 25°C; T = 150°C; α = −0.0001 /°C.
Third find ΔT = T − T0 = 150 − 25 = 125.
Fourth compute α × ΔT = −0.0001 × 125 = −0.0125.
Fifth add 1: 1 + (−0.0125) = 0.9875.
Sixth multiply: f = 1,000,000 × 0.9875 = 987,500 Hz.
So the sensor reads 987.5 kHz at 150°C.
FAQs
Q: Can I use any base frequency?
A: Yes, you can. Use the sensor spec.
Q: What if α is positive?
A: Then frequency will rise with heat.
Q: Is this exact?
A: It gives a linear estimate. Some devices may vary.
