Section 1: Common Tools for Electricians 1. Common Tools for Electricians 1. Pliers The pliers category includes wire cutters, rubber-handled pliers, needle-nose pliers, tensioning pliers, and wire strippers (as shown in Figure 6-1). Wire cutters are used to cut cold-rolled steel wire. Tensioning pliers are used to tighten lines during the installation of overhead lines … Read more
Second Topic:Difference Between Average Response Principle and True RMS Principle FLUKE’s digital multimeters and clamp meters differ between average response and true RMS. For example, the well-known F15B+/F17B+ series are average response multimeters, while the F115C/F117C series are true RMS multimeters. So what are the differences between them? How should users make their choice? What … Read more
1. Introduction In the production of electronic cones, it is necessary to detect a 20kHz electromagnetic navigation signal to unify the reset state of the electronic cone indicator. To reduce detection costs, the LM567[2] audio signal detection chip is used to detect the electromagnetic navigation signal. This DIP8 packaged LM567 is convenient for testing on … Read more
With the rapid development of modern ship technology, the operation of ME electronic fuel injection engines has become increasingly stable, and new ships are increasingly adopting ME electronic fuel injection engines. Compared to the traditional MC engines, the ME electronic fuel injection engines have made significant changes in pneumatic remote control. The pneumatic control system … Read more
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
