1 Development and Classification of Data Acquisition Instruments As shown in Figure 1, in vibration noise testing, we focus on the final test analysis results, such as the time-domain and frequency-domain characteristics of the signals. To analyze the data, we need to acquire it. Directly obtaining physical quantities is quite challenging, especially for high-frequency physical … Read more
Today, we bring you the wiring methods for sensors and PLCs, featuring twenty wiring diagrams. Isn’t that a wealth of information? Let’s take a look together! Overview The digital input interface of a PLC is not complex. To enhance anti-interference capability, PLCs use opto-isolators to isolate the input signals from the internal processing circuits. Therefore, … Read more

A sensor is a detection device that can sense the information being measured and convert that information into electrical signals or other required forms of output according to certain rules, in order to meet the requirements for information transmission, processing, storage, display, recording, and control (for example, the oxygen sensor on a catalytic converter detects … Read more
According to MEMS Consulting, researchers at The University of Manchester have proposed a simple and cost-effective method for monitoring respiratory function and metabolic rate using a wearable piezoelectric airflow transducer (WPAT). The researchers designed a self-protecting bending sensor by bonding two uniaxially stretched piezoelectric poly-L-lactic acid films cut at different angles, and then installed the … Read more
This week, I studied the first half of Chapter 3, which mainly discusses electrical principles. This chapter starts with the most basic and easily understandable component, the resistor, and then introduces commonly used concepts such as voltage and temperature coefficient. It then discusses electromigration, a phenomenon that needs to be avoided in design to prevent … Read more
