Le thermostat peut être utilisé avec une charge maxi- male de 15 A (soit 1800 W @ 120 V c.a. in mV according to the temperature difference between the sensor tip θ1 and the gauge head θ2 such that e = α(θ1-θ2) + β(θ12-θ22) Given α = 3.5 x 10-2 and β = 8.2 x 10-6 determine the mV output when the tip is at 220oC and the Discrete event, or on/off sensor, changes its state based on the occurrence of some external event. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control. The default resolution at power-up is 12-bit. The voltage on the center pin changes as it gets warmer or cooler. All the code in this user guide is also compatible with these boards. A temperature sensor of another sort (often a semiconductor sensor, sometimes a thermistor) measures the temperature of the cold junction and is used to inject a voltage into the thermocouple circuit which compensates for the difference between the actual cold junction temperature and its ideal value (usually 0°C) as shown in Figure 7.8. The ECU also uses this data to determine how much the ignition timing should be advanced as well as the proper setting for the ISC to maintain the proper idle speed. SENSOR LETTERS Vol. We’ll cover how to wire the sensor, install the required libraries, and write the code to get the sensor readings from one and multiple sensors. The tempco is typically -2.2mV/degree C, but can vary some with the exact device used. the %change of some property of a device (eg gain) as a result of a % change in some parameter, (eg the ambient temperature).
