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.

With the development of electronic technology, especially large-scale integrated circuit and computer technology, frequency weighting, detector and filter circuit in sound level meter are all realized by digital signal processing technology instead of analog circuit. This not only makes the circuit simpler and wider dynamic range, but also greatly improves the function and stability, especially for real-time spectrum analysis. A sound level meter is an instrument that measures the sound pressure level and sound level according to a certain frequency weighting and time weighting. It is the most commonly used instrument in acoustic measurement, which can approximate the noise level of industrial noise, traffic noise, environmental noise and living noise according to the characteristics of human hearing. It can be applied to the measurement of environmental noise, mechanical and electrical product noise, traffic noise, architectural acoustics and electro-acoustics.

An air motor (pneumatic motor), or compressed air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion. With proper using and maintenance, you can be sure that your air motor will maintain a high level of performance for many years. And it is easy to maintain an air motor. Basically, there are two key elements to pay attention to: lubrication and filtration.

The air source used must be effectively filtered. Sometimes a secondary filter is required. Filters should be cleaned in time. Otherwise: water, oil and dust/ dust particles can enter the ion generation chamber and adhere to the inner wall of the plastic component. At a certain point, the ionic needle ignites it. Results cellular coke loss was gradually formed in plastic parts, and ion discharge decreased gradually. In particular, it creates security risks.

An air motor is a device that converts the pressure energy of compressed air into rotational mechanical energy. Typically used as a source of rotational power for more complex devices or machines. Air motors are classified by structure into: vane air motors, piston air motors, compact vane air motors, and compact piston air motors. The air motor is a relatively precise power machine. It is strictly forbidden to knock or disassemble it during installation. It does not bear axial force, please install and use the air motor under the correct requirements.

As the key elastic element of the diaphragm coupling, the diaphragm bears the main load during operation. When the diaphragm shaft coupling rotates, its angular offset will generate alternating stress, which alternates once per rotation. The dynamic stress of the diaphragm will lead to the fatigue damage of the diaphragm and the bolt, so the accurate calculation of the dynamic and static composite stress is the key to predict the life of the diaphragm shaft coupling and the operation of the diaphragm shaft coupling.

Static eliminators are products that protect susceptible items from the effects of static discharge. There are rules that must be followed in static elimination. A thorough understanding of these principles is necessary to obtain the best performing equipment. The following will clarify some issues to consider when choosing static elimination.

Compared with piston motors of similar power, vane air motors are smaller, lighter and less expensive. Simple design and construction allow them to operate at any installation angle in most cases. The vane motor has a wider range of speed, torque and power and is the most commonly used form of air motor.

Shaft couplings are mechanical parts used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are respectively connected with the driving shaft and the driven shaft. Most of the general power machines are connected with the working machine by means of couplings.
