Thread Content
Briefly describe the structure and functions of each part of the digital thermal display instrument. The structure and functions of each part of the digital thermal instrument are as follows.: (1) Sensor: It provides digital display meter for input signal, voltage or current signal. (2) Amplifier: It amplifies the input voltage or current signal. (3)A/D converter: That is, the analog-to-digital converter, which is the core of digital instruments. Its function is to convert continuous analog voltage signals into discrete digital signals and display the measurement results in digital form. (4) Linearizer: Usually the sensor has a nonlinear functional relationship, and its function is to eliminate nonlinear errors. (5) Storage and display: Register and digitally display the output signal of the A/D converter. (6) Control logic circuit: Control the entire machine and coordinate the work of each component. (7) Alarm circuit: Alarm the upper and lower limits of the measured parameters. This post was last edited by Mobei Yihai on 2009-2-22 15:56 ]
Thermal instrumentation consists of sensing parts, middleware and display parts. The sensing element is directly connected to the measured object, feels the changes of the measured parameters, and converts the measured parameter signals into corresponding signal outputs that are convenient for measurement and display. The middleware directly transmits the signal output by the sensor to the display element, or amplifies and converts it into a signal adapted to the display element. The display reflects the magnitude and change of the measured parameter to the observer.
