There are various types and structures of precision instruments. For precision instruments used for measurement, their structure can be divided into eight functional components: reference, sensing conversion, conversion amplification transmission, aiming/reading, data processing, display recording, drive control, mechanical structure, etc. But it does not mean that a precision instrument must include the eight functional components mentioned above, but should be selected according to the requirements of the instrument's functions.
1. Reference components
The reference component provides a standard quantity for measurement, and the measurement results must be compared with it to obtain accurate measurement values. Therefore, it is the main link that determines the accuracy of precision instruments.
There are many types of reference devices, such as standard devices used for measuring geometric quantities (length and angle): measuring blocks, precision measuring screws, line rulers, dials, polyhedral prisms, multi tooth indexing disks, grating rulers (disks), magnetic grating rulers (disks), induction synchronizers, light waves, etc. For complex parameters, there are standard components such as involute templates and surface roughness templates, as well as standard circular motion, involute motion, and gear motion devices that provide standard motion. In addition, there are standard hardness blocks, frequency meters, as well as standards for time, illumination, flow rate, chromaticity, laser parameters, temperature, force measurement, weighing, etc. You can choose according to your needs.
2. Feel the conversion components
The sensing conversion component senses being measured, picks up the raw signal for further conversion, processing, and analysis. Its accuracy directly affects the accuracy of the entire instrument.
Some instruments have sensory conversion components that only function to sense the original signal, while others also perform a signal conversion at the same time. There are two main types of sensory conversion components: one is contact type, such as various mechanical probes; One type is non-contact, such as pneumatic non-contact probes, optical probes, infrared, eddy current probes, pickups, etc.
