Thus, optical fiber measurement has entered into a new period of digitization.

Ultrasonic distance sensors are designed to measure the distance to a remote object through the air without physically touching it. Distance sensors determine this value by emitting high-frequency or ultrasonic soundwaves toward the object being measured, receiving the reflected wave, and calculating the time between emission and reception. While this broad selection makes it possible for customers to find a ultrasonic distance sensor that suits their unique application, it can also make it more difficult to determine which one is right. When we choose ultrasonic distance sensors, we should consider several problems. Here is a brief introduction about what they are.

At present, with the continuous improvement of people's living, various industries pay more and more attention to the temperature and humidity management environment of product production, equipment and warehouse storage. Therefore, it is necessary to use the temperature data loggers. The temperature and humidity data logger measures the temperature and humidity parameters and stores them in the recorder according to predetermined time intervals or uploads them to the computer cloud platform through Bluetooth or USB. The data logger can be exported and analyzed to ensure that whether there are any incidents that endanger the safety of the product during the storage and shipping. However, which industries need temperature and humidity monitoring systems?

The realization of the overload protection function of the miniature circuit breaker is based on the principle that bimetals bend in a regular direction as the temperature rises. After the miniature circuit breaker is closed, it is in normal working condition. The inner bimetal is heated by a certain current passing through it. The two pieces of metal have different thermal expansion coefficients and cause bending.

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flows into torque and angular displacement (rotation).

It also plays an important role in heavy industry, like mining, petroleum, metallurgy and pressure processing.

Variable Frequency Drive universal frequency converter is a power control device that controls the AC motor by changing the frequency of the working power supply of the motor, and converts the power frequency AC power with constant voltage and frequency into voltage or frequency by applying the principle of frequency conversion technology and microelectronic technology The working process of the variable AC power device is to first convert the power frequency AC power supply into a DC power supply through a rectifier, and then convert the DC power supply into an AC power supply with controllable frequency and voltage to supply the motor.

The full name of OTDR is Optical Time Domain Reflectometer. An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer. OTDR is widely used in the maintenance and construction of optical cable lines, and can measure optical fiber length, optical fiber transmission attenuation, joint attenuation and fault location.

Gas detectors are usually used to detect toxic, harmful or flammable gases. Toxic gas detectors are generally used in biochemical, pharmaceutical, construction and other industries, while combustible gas detectors are often used in coal mines, petroleum, chemical, fuel and other industries. With the rapid development of the industry, the monitoring of gas in the environment is essential, so how should we choose a gas detector? At present, there are portable gas detectors and fixed gas detectors provided by manufacturers and supplies. These two types of gas detectors are divided into 1 in 1, 2 in 1, 4 in 1 and other specifications, and these products with different specifications have different application functions for gases. The detection standards for different industries and occasions are different, and the detection standards for different gases are also different.
