What does 'side' mean on a car?
1 Answers
Automotive 'outside' refers to the external temperature, indicating that the outdoor temperature is lower than the indoor temperature. Below is relevant information about temperature sensors: 1. Working principle: Sensors designed based on the principle of metal expansion. Metals produce a corresponding extension when the environmental temperature changes, so the sensor can convert this reaction into signals in different ways. A bimetallic strip is composed of two metals with different expansion coefficients bonded together. As the temperature changes, material A expands more than the other metal, causing the strip to bend. The curvature of the bend can be converted into an output signal. 2. Selection method: To achieve reliable temperature measurement, the first step is to choose the correct temperature instrument, which is the temperature sensor. Thermocouples, thermistors, platinum resistance (RTD), and temperature ICs are the most commonly used temperature sensors in testing.
