I. Overview
The thermocouple vacuum meter is a new type of vacuum measuring instrument that uses computer technology to nonlinearly process vacuum measurement data.
It improves the measurement accuracy and increases the stability of the display. It is an advanced vacuum gauge. Widely used in aerospace, machinery, petroleum, chemical,
Low temperature liquid storage and transportation equipment, metallurgy, electronics and medical fields. The product complies with JB/T6873-2005.
2. Working principle
According to the heat transfer characteristics of gas molecules under low pressure, when the heating current of the thermocouple gauge hot wire is constant, the temperature of the hot wire will follow the pressure inside the tube.
Strong and change, when the pressure is reduced, the heat conduction motion of the gas molecules is weakened, and the temperature of the hot wire is increased; otherwise, the temperature of the hot wire is reduced, heat
The thermoelectric potential of the even tube output reflects the change in the temperature of the hot wire. As long as the thermoelectric potential of the gauge is measured, the corresponding system pressure is determined.
The thermoelectric potential of the regulated output is sent to the digital tube after being nonlinearly processed by the computer.
