What is Vibration Meter?

Vibration meter is an instrument used to measure the peak value, peak-to-peak value, average value or root mean square value of vibration such as velocity, acceleration and displacement. The vibration meter can be applied in mechanical manufacturing, electric metallurgy, general aviation etc. The main parts of this instrument are integral differential circuit, amplifying circuit, voltage detector and meter head. The integral differential circuit is used to complete the integral differential operation between the above vibration quantities. Generally, integral and differential operational amplifiers can be used, low-pass filters and high pass filters can also be used to complete integral differential operations. However, we should pay attention to this instrument's application frequency range when we are using it for calculation. The vibration meter can only obtain the total intensity (vibration level) of the vibration, but cannot obtain other information, so its scope of using is limited.

What is a Current Transformer?

A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side based on the principle of electromagnetic induction. The current transformer is composed of a closed core and windings. Its primary winding has a few turns and is stringed in the line of the current that needs to be measured. According to different uses, current transformers can be roughly divided into two categories: current transformers for measurement and current transformers for protection.

How to Use the Tool Setter?

According to the relevant data and practice, the repeatability of the tool setting probe is 1 um, and that of the chuck less than 15 inches is 5 um. The repeated accuracy of the tool arm can reach 8um for the chuck of 18 inches and above. This precision can meet the needs of most users without trial cutting. The use of tool setting instrument reduces the auxiliary time of the machine tool and reduces the rework and scrap rate. The efficiency and accuracy of the machine tool can be significantly improved when the machine tool is used from the beginning to the end.

The current transformer is composed of a closed core and windings. Its primary winding has a few turns and is stringed in the line of the current that needs to be measured. This article will introduce the principles and precautions that should be paid attention to in the actual application of current transformers.

What Are the Functions of Current Transformer?

A current transformer is an instrument that converts a large current into a small current according to a certain transformation ratio. Current transformers are generally used to measure large currents. In modern technology, it is difficult to produce an AC instrument that can directly measure large currents, and even if they are manufactured, they will be brought to us when we use them. It's very dangerous. For this reason, clever technical engineers have manufactured current transformers based on the principles of transformers. In practical applications, current transformers also play many important roles. The following article will talk about the role of current transformers.

Types and Functions of Limit Switches

Introduction of limit switch
Limit switch is a kind of sensor to detect and control the mechanical movement beyond the limit displacement. For example, the position limiter of electric rolling shutter gate ensures that the motor will stop working when the gate is opened or closed to the specified position, so as to ensure that the motor and mechanical components will not be damaged due to excessive work. The commonly used limit switches include all kinds of travel switches, micro switches, and photoelectric switches. In short, as long as the corresponding detection device is equipped and the functional requirements are completed, they can be used as limit switches.

How to Use Air Blower?

The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base, drip nozzle. The blower operates eccentrically on the rotor offset in the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air. The pressure difference of the blower is used to automatically send lubrication to the drip nozzle, and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from returning. This type of blower is also called a sliding vane blower. This article will talk about the use of blowers.In order to ensure personal safety, the operator must be familiar with this regulation before starting, and operate the blower strictly in accordance with this regulation.

What is Displacement Sensor?

Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. According to the different forms of the measured variable, the displacement sensor can be divided into two types: the analog type and the digital type. The former can also be divided into two types: the physical type and the structure type. Commonly used displacement sensors are mostly analog structures, including potentiometer type displacement sensors, inductive displacement sensors, self-aligning machine, capacitive displacement sensors, eddy current displacement sensors, and Hall-type displacement sensors.

How to Use Conductivity Meter?

Conductivity meter is an instrument and equipment suitable for precise measurement of various liquid media, mainly used to accurately measure the conductivity of liquid media.

How to Maintain the Dryer?

Before the dryer enters normal work, there will be a period of adaptation (run-in period, generally 3 days). This period is to ensure that the dryer can work normally during the formal production process and minimize the number of dryers. The probability of an accident, the correct operation during the adaptation period can prolong the service life of the dryer, so we must pay attention to the details of each operation during this period.
