A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity meets the specified requirements. It has the interactive relationship between the control system and the controlled system. Usually used in automatic control circuits, a relay is actually an automatic switch that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

Thermal overload relays are overload relays that apply the principle of current thermal effect and use electrical thermal bimetallic sheets as sensitive components. The electrical thermal bimetal sheet is made by heating and rolling two alloys with large difference in linear expansion coefficient. When heated, the bimetallic sheet bends from the high expansion layer to the low expansion layer. When the current is too large, the element acts due to "heat", so that its linked moving contact cuts off the power supply of the controlled circuit and the protected equipment.

The dedicated solid state relay has the functions of short circuit protection, overload protection and overheat protection. It can realize the intelligent module required by the user and directly use it in the control system with the combination logic curing package. SSR can use external analog signal to trigger the module to achieve linearly adjustable output voltage.

Can industrial water chillers be cleaned with acid? To be sure, pickling as a cleaning method can be applied, but the degree of dilution of the acid and the type of acid must be considered. Air cooled industrial water chiller with full power, built-in stainless steel insulated water tank, durable and easy to clean. Basically, almost all condensers can be cleaned with pickling. In addition, you also need to consider the parts of the chiller that you want to clean, whether it is local cleaning, or the entire system is cleaned and cleaned in a cycle, these two aspects are completely different.

The electric diaphragm pump is a relatively new type of mechanical transportation equipment. It has the advantages of no need for irrigation and water diversion, strong self-priming ability, high pressure, low vibration, arbitrary flow adjustment, and can transport flammable, volatile, and acid-corrosive liquids. Therefore, electric operated diaphragm pump is often used in petrochemical, ceramics, metallurgy and other industries, and occupies a certain leading position in spray painting and ceramics. Next we will troubleshoot the EODD pump.

Colorimeters are commonly used analytical instruments in laboratories and laboratories at all levels. It is the most popular among analysts of all levels due to its simplicity of operation, ease of use, wide range of use, and high accuracy and precision. The wavelength needs to be corrected, but during use, the shape and movement of the speaker can cause the speaker to produce different wavelengths due to various factors. There are many ways to correct the wavelength. In this article, we will introduce two approaches.

The Diaphragm pump, also known as control pump, is the main type of actuator. It changes the fluid flow with the help of power operation by receiving the control signal output by the adjustment control unit. The function of the diaphragm pump in the control process is to accept the control signal of the regulator or computer, change the flow rate of the adjusted medium, and maintain the adjusted parameters within the required range, so as to achieve the automation of the production process.

Peristaltic pump is a kind of hose pump, relying on the flexibility of the hose to work, both can be continuous transmission, can also be filled, the liquid only flows through the hose, so the health grade is higher in all pump types. Peristaltic pump has good self-sealing performance and can be simplified in the design of pipeline. Therefore, in recent years, more and more filling machinery began to use peristaltic pump as a filling unit. However, because of some of the structural characteristics of peristaltic pump, there will be a problem of transmission accuracy in the use of peristaltic pump. The reasons and solutions will be explained in detail below.

A solid state relay is an all-electronic circuit combination component that relies on the electromagnetic and optical properties of semiconductor devices and electronic components to complete its isolation and relay switching functions. Compared with the traditional electromagnetic relay, the solid state relay is a relay without machinery and no moving parts, but has essentially the same function as the electromagnetic relay.

Gas detector is a kind of gas leakage concentration detection instrument tool. ATO sells portable gas detector that continuously and rapidly monitors specific concentrations of gases in the surrounding environment or confined spaces. But it in use after a period of time due to multiple sensor detection, there may be misoperation and other reasons, may lead to increased errors in the gas detector, measurement data is not accurate. In this article, we will introduce the calibration of gas detectors.

Solid state relay, short for SSR, is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control terminal and the load terminal. The input end of the solid state relay uses a tiny control signal to directly drive a large current load. So, how to maintain a solid state relay?

The float level switch is simple in structure, easy to use, stable in performance, long in service life, and easy to install and maintain. It is almost suitable for liquid level measurement and control in various industrial automation process control, and is widely used in petroleum, food, chemical, water treatment, liquid level measurement, control and monitoring in the fields of pharmacy, electric power, papermaking, metallurgy, ships and steel furnaces.

There should be no obstacles in the area radiated by the emitted ultrasonic beam between the emitting surface of the ultrasonic liquid level sensor probe and the surface of the medium to be measured. Therefore, the installation should be avoided as far as possible from the internal facilities, such as brackets, on-site equipment and so on. When installing the level sensor, the sensor must be kept at a certain distance from the tank wall, and the transmission direction of the transducer should be perpendicular to the liquid surface as much as possible.
