7.3.4 Level Sensors (1) Concept A level sensor is a device used to detect, measure, and monitor the height of liquid, slurry, or solid material surfaces. It converts the height information of the liquid level into an electrical signal output according to certain rules, facilitating display, alarm, recording, or control, with the function of achieving … Read more
7.3.2 Pressure Sensors (1) Concept A pressure sensor is a device that converts pressure signals (primarily the pressure of gases or liquids) into quantifiable electrical signals. Its working principle involves pressure acting directly or indirectly on the sensor’s pressure-sensitive element (such as piezoresistive, capacitive, or piezoelectric elements), causing changes in the electrical parameters (such as … Read more

Piezoelectric accelerometers operate based on the piezoelectric effect, generating charge signals through the inertial force acting on the piezoelectric element from a mass block, achieving electromechanical conversion of acceleration. 1、Working Principle and Core Mechanism The core principle of piezoelectric accelerometers is to utilize piezoelectric materials to convert mechanical vibrations into electrical signals. The specific process … Read more
A multimeter, also known as a multi-tester, is a multifunctional and multi-range measuring instrument. Generally, a multimeter can measure direct current (DC) and voltage, alternating current (AC) voltage, resistance, and audio levels. Some models can also measure AC current, capacitance, inductance, and certain parameters of semiconductors. It is a commonly used tool for electricians. 1. … Read more

Multimeter Usage Mnemonics Check the range before measuring; do not measure without checking. Do not change the range while measuring; switch to the off position after measuring. The dial should be level, and the reading must be aligned correctly. The range must be appropriate, and the reading should be aligned correctly. Measure resistance (R) without … Read more
Atlas’s foray into advertising has left the entire industry shrugging. Last Friday, Facebook announced that it would gradually cease the Ad server services of the Atlas platform over the coming months, while continuing to operate the Atlas measurement tool. Facebook’s advertising technology structure has begun to diverge significantly from what it was when it acquired … Read more
Common Mistakes in Choosing Oscilloscope Probes In oscilloscope measurements, the choice of probe directly affects the accuracy of the results. The probe acts as a “bridge” between the oscilloscope and the device under test (DUT), and its performance directly determines the accuracy, completeness, and reliability of the oscilloscope measurement results. However, many engineers tend to … Read more
