Outer diameter: The outer diameter (OD) of the friction washer is the diameter of the outer edge of the washer. It is usually measured in inches or millimeters.
Inner diameter: The inner diameter (ID) of the friction washer is the diameter of the inner hole of the washer. It is usually measured in inches or millimeters.
Thickness: The thickness of the friction washer is the distance between the upper and lower surfaces of the washer. It is usually measured in inches or millimeters.

- Signal detection circuit module
Mainly composed of thermocouples, operational amplifiers 27L2, DS18B20, and ARM7 internal AD. Convert temperature into a digital signal that the processor can recognize.
The temperature acquisition circuit of this design is shown in Figure 2. Pins 1 and 3 of the P6 port are connected to the positive end of the thermocouple sensor, and pins 2 and 4 are connected to the negative end of the thermocouple sensor. After the thermocouple collects the signal, high-frequency clutter is filtered out by C00 and C10 (high-frequency filtering capacitors), and then amplified by 27L2 (low-frequency small signal amplifier). The ratio of the sum of R64 and R63 to R65 is the amplification factor of U3B. Similarly, the ratio of the sum of R60 and R62 to R61 is the amplification factor of U3A. After amplification, high-frequency clutter is filtered out through C01 and C11, and finally the signal is transmitted to ARM7. The analog voltage signal is converted into a digital signal that the processor can recognize through its internal AD converter. When the temperature of the probe part of the thermocouple sensor changes, the voltage at both ends of the thermocouple sensor also changes in a certain proportion. Then, the voltage signal is amplified by 27L2, and the analog signal is converted into a digital signal by the internal AD of ARM. After obtaining the digital signal, the ARM processor knows the current temperature. Of course, a thermocouple temperature measurement module alone is not enough for accurate temperature measurement. -
