Expert Thermocouple & RTD &Temperature Sensor Manufacturer.
Thermocouple sensor is a kind of testing instrument is commonly used in daily life, in a number of areas of has a certain application, People's Daily life is inseparable from the thermocouple sensor. Thermocouple sensor is very important for users, the performance of the new thermocouple sensor can, of course, is the higher the better. Users can always ask what method to improve the performance of the thermocouple sensor? Engineering is to solve the problem for you today, to introduce the way to increase the thermocouple sensor performance.
zero method
zero method refers to the amount is measured with standard compare to, when to reach equilibrium, the instrument null, at this point is equal to the amount of specification is measured. Mechanical balance is a typical example.
closed loop technology
application closed-loop system consisting of a negative reaction, can make the system widen the bandwidth, increase the dynamic range, progress flexibility and resolution, stability, repeatability and solid progress. A compensation and correction techniques are sometimes thermocouple sensor is too complex, adopted a certain technical measures is still difficult to satisfy the request, or can satisfy the request, but because of the cost is too high or too complicated and no practical significance. This is to be able to find out the direction of the error and numerical, fixed way to compensate or correction. For example, nonlinear, temperature difference and other commonly used the method.
compensation and correction, to application of electronic technology through the line to deal with, also can accomplish through software by single chip microcomputer. The application of the latter is more and more common.
differential method
differential method is based on the zero method to carry out, because of the zero method request is complete equal amount of measurement and specification, therefore the request specification is continuous variable, it is often not easy to do. But if the specification and measurement difference reduce to a certain level, the reverend mother because they cancel each other out effect, can make the indicator instrument error influence greatly weakened, this is the principle of error method. This way because of the continuous adjustable amount of not requirements specification, at the same time, may be on the indicating meter direct reading glass tube thermocouple numerical, thus widely application.
