Accelerometer sensors are ICs that measure acceleration, which is the change in speed (velocity) per unit time. Measuring acceleration makes it possible to obtain information such as object inclination and vibration. It is usually composed of mass blocks, dampers, elastic elements, sensitive elements and adaptive circuits. During the acceleration process of the sensor, the acceleration value is obtained by using Newton's second law by measuring the inertial force on the mass block.

We are interested in knowing how to disassemble the water-cooled spindle of a CNC engraving machine to clean waterway impurities. In fact, the correct approach is not to disassemble the water-cooled spindle for cleaning, because the structure of the water-cooled spindle is quite complex, non-professionals to disassemble easy to damage the spindle, affecting the concentricity of the spindle components and parts of the connection assembly, must be disassembled to clean up, should be handed over to the manufacturer to carry out.

For the generator working in order, maintenance at fixed period is very important. The diesel generator is consisted of a diesel engine, alternator, control panel, frame, etc. Please read the relative manual for the maintenance.

Before maintaining the generator, stop the engine. The surrounding condition of the generator is of better ventilation because engine exgaust includes harmful CO. After stopping the generator, clean it immediately to prevent corrosion and remove the sediment.

A centrifugal pump is a mechanical device designed to move fluid by transferring rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and exits through the impeller's blade tips along its circumference by centrifugal force. The action of the impeller increases the velocity and pressure of the fluid and directs it towards the pump outlet. The pump casing is specially designed to compress the fluid from the pump inlet, direct it to the impeller, and then slow and control the fluid before discharging.

The linear servo motor is a modular product integrating servo motor and screw, the electric linear servo motor converting the rotary motion of servo motor into linear motion, while converting the best advantages of servo motor - precise speed control, precise rpm control and precise torque control into precise speed control, precise position control and precise thrust control; a new revolutionary product that realizes high precision linear motion series.

ATO anemometers are used in health supervision, environmental monitoring, health and epidemic prevention, university academies, food safety, industrial pollution, heavy metal dyes, potions, chemicals, beverages, bacteria, sewage, pulp, pharmaceuticals, fermentation, electroplating, drinking water production workshops, Planting, breeding and fishing sites. Here's how to use an wind anemometer and its precautions:

Crane scale is a tool for measuring weight. The electronic crane scale is generally composed of a mechanical load-bearing mechanism, a load cell, an A/D conversion board, a power supply, a wireless transmitting and receiving device and a weighing display instrument. So how do we choose? Generally speaking, when choosing an electronic crane scale, you should pay attention to the following aspects: accuracy, measurement range, function, versatility, etc. Let's take a look at the details below.

AC Servo drive is a controller used to control servo motors. Today, more and more users have it. ATO AC servo drives are widely used in automation equipment such as industrial robots and CNC machining centers. The following introduces how to install and wire the AC servo drive correctly.

There are many types of rubber sheet, any kind of rubber sheet produced by the material, is composed of the main material and a variety of coordination agent mixed multi-component system materials, each component plays a certain role. For example, the vulcanization system can make the linear rubber macromolecules through chemical cross-linking, forming a three-dimensional space network structure, so as to change the plastic viscoelastic rubber into high elastic vulcanization.

A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output. The generated signal can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data acquisition system, or can be used for the purpose of control. This article will explain how to use current sensor correctly.

In order to understand pickup ability to compare magnets, you need to know how we measure pickup ability and performance. We briefly introduce in this article. The weight form of the steel is very important. For example, a 50-pound nail is harder to "grab" than a 50-pound rebar. The rebar is flat and dense and can be very close to where the magnet's gauss strength is highest, allowing the magnet to "grab" more weight in the form of the rebar than in the form of a nail.

As with all continuous output pressure sensors, regardless of the application, the most sensitive component to the sensing diaphragm and most critical to the function of the pressure sensor is the sensing diaphragm. If it doesn't work, your readings will be incorrect, or in extreme cases, you will have no readings at all. 

Industrial endoscope is widely used in aerospace, energy and electric power, automobile manufacturing, fine chemicals and other fields, because it is an important tool for nondestructive testing, it must be well maintained and maintained in daily work. Such as handle gently and prevent damage; timely cleaning and safekeeping; lens and probe protection and so on. These are some common maintenance of endoscope. In this article, we will introduce maintenance of industrial endoscope in detail.

Industrial endoscope is a kind of visual inspection in NDT (nondestructive testing). When talking about the operation of industrial endoscopes, we have always thought just insert the probe into the inspected area, adjust the brightness, do the clarity, find the best viewing angle, and then inspect in real-time monitoring.

For most engineering applications, choosing a suitable pressure sensor will have an important impact on the accuracy of the entire engineering measurement and the progress of the project. There are many types of pressure sensors available today. How to select a pressure sensor reasonably according to the specific measurement purpose, measurement object and measurement environment is the first problem to be solved when measuring a certain quantity.

Soil moisture is an important part of soil and plays a very important role in crop growth and water-saving irrigation. The soil moisture meter grasps the distribution of soil moisture (water) through the GPS positioning system, providing a scientific basis for differentiated water-saving irrigation. At the same time, accurate water supply is also conducive to improving crop yield and quality.

Pressure sensor is a device that senses a pressure signal and converts the pressure signal into a usable output electrical signal. Under the interference of external factors, the output of the sensor usually has unneeded changes that have nothing to do with the input. This type of change is called "temperature drift", and the main reason for drift is that the sensitive components of the measurement system are usually easily interfered by external temperature, humidity, electromagnetic interference and sensor conditioning circuits.

The sound level meter measurement is to convert the vibration wave signal of the metal diaphragm of the microphone (microphone head) at the front of the sound level meter into an electrical signal through the vibration wave caused by the sound signal (sound wave), and then pass through the special weighting network and circuit. After the operational amplification, the noise decibel value is displayed by digital or meter.

Static eliminator refers to the production and life used to eliminate static equipment. The static eliminator should be installed in the place where the electrostatic potential of the charged body is highest. The electrostatic tester can be used to measure the whole production line and find out the position of the highest electrostatic.

Multi-cell dry batteries are the most used in sound level meters, but batteries have their service life. Sometimes when the battery voltage is insufficient, the measured data will be inaccurate. This requires timely replacement of batteries when they are used to a certain extent. Usually, the sound level meter will set the indicator to check the battery status. Just press the battery check button, and the voltage of the battery can be displayed at a glance.
