DIP switch, also known as dual in-line package switch, is an address switch for operation control, using the principle of 0/1 binary code. The DIP switch is mostly used in the program control board to control the conduction and disconnection of the performance circuit of the component. There are two pins on the upper and lower sides of the back corresponding to each key of the DIP switch. When the DIP switch is on the ON side, these two pins are connected, otherwise disconnect. The four keys are independent and unrelated to each other. These elements are mainly used for binary encoding.

Ultrasonic thickness gauges measure thickness according to the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is reflected back to the probe, which is determined by accurately measuring the propagation time of the ultrasonic wave in the material. The thickness of the material being measured. This principle can be used to measure all kinds of materials that can make ultrasonic waves propagate inside them at a constant speed.

The performance, shelf life, and service life of all capacitors depends largely on the environmental conditions in which they are exposed. Not only must the relationship of a single environmental factor to the capacitor, but also the effect of different combinations of these environmental factors be considered. The main environmental factors that affect the performance and life of capacitors are ambient temperature, humidity, vibration, shock, acceleration and atmospheric pressure, etc. The impact of these single environmental factors is briefly discussed as follows.

Centrifugal pumps are currently utilized across a vast array of domestic and industrial processes. From supplying the water used in residential buildings to industrial applications like food, beverage, and chemical manufacturing, different types of centrifugal pumps are required to effectively meet pumping requirements. The centrifugal pumps can be classified based on many factors such as construction, design, application and industrial standards. Therefore, one centrifugal pump can be placed into different groups at the same time. In this article, we will introduce three classifications of centrifugal pumps.

The handheld distance meter is based on the use of electromagnetic wave science, optics, acoustics, and other principles and has a compact body, used for distance measurement instruments. Principle: The handheld distance meter shoots a very thin laser beam to the target when working, and the laser beam reflected from the target is received by the photoelectric element, and the timer determines the time from the emission to the reception of the laser beam to calculate the distance from the observer to the target.

Mud pump, refers to the drilling process to the drilling mud or water and other washing liquid machinery. The main components are volute, impeller, pump seat, pump case, support cylinder, motor seat, motor and other components. Impeller nut is cast iron, so corrosion resistance is good, and convenient processing technology. High quality vertical mud pumps with thick, solid shaft and copper motor can be provided in ATO shop. In this article, we will show the price list of vertical mud pump.

A water chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. With the continuous development of chiller industry, more and more human beings begin to pay attention to the chiller industry, and industrial water chiller is becoming more and more important to human beings. Water chiller is mainly divided into air cooled water chiller and water cooled water chiller. In this article, we will introduce these two types of water chillers in ATO online shop.

Oscilloscopes is an important test tool in electronic engineering. Especially when we measure a repetitive waveform or high frequency signal, it has a great effect. However, beginners will have a question: analog oscilloscope or digital oscilloscope, which one is better? However, in most cases, you will find that digital oscilloscopes are more expensive than analog oscilloscopes. In this article, we mainly introduce the differences between analog and digital oscilloscope.

Visible spectrophotometer can perform quantitative measurement, DNA/protein test, total phosphorus and nitrogen test, heavy metal test, pesticide residue test, food safety test, thermal power generation metal ion test, etc. Widely used in food, medicine, electricity, biology Research, teaching and scientific research, chemistry and chemical industry, quality supervision, water quality and environmental protection and commodity inspection and other major fields.

ATO digital rotary torque sensor with LCD display has the capacity range from 0.1 Nm/0.3 Nm/1 Nm/5 Nm/10 Nm/300 Nm/1000 Nm to 10000 Nm. LCD display can show torque, speed and power value at the same time. This article shows you how to wire and set a torque sensor in Modbus mode via S484 interface as a walkthrough of one of the applications of ATO torque sensors.

Linear DC power supply is to first reduce the voltage amplitude of alternating current through a transformer, and then rectify it through a rectifier circuit to obtain pulsed direct current, and then filter to obtain a direct current voltage with a small ripple voltage. To achieve high-precision DC voltage, it must be regulated by a voltage regulator circuit.

An oscilloscope, a benchtop instrument, graphically displays electrical signals and shows how those signals change over time. They are used by engineers to troubleshoot circuits and check signal quality. Most engineers use digital oscilloscopes. Digital oscilloscopes are used to acquire and store waveforms, display the voltage, frequency, noise portion of the signal, detect whether the signal is distorted, the time interval between signals, etc. But when it comes to choosing an oscilloscope, how do you know which oscilloscope is right for you? The following 7 factors need attention.

More than 60% air provides the perfect environment for mold and dust mites to thrive, which can cause nasal congestion, sneezing, coughing, and even wheezing. Too much moisture can also cause problems in your house, including cracked wood furniture and floors, promoting mold growth on carpets, and rusting your toilet tank and plumbing. A dehumidifier can help you reduce moisture in the air, but it's only effective when used correctly. Here are 5 mistakes not to make when using a dehumidifier.

A spectrophotometer is a measuring instrument that samples reflective or transmissive objects with discrete wavelengths. Due to the different molecular structures of different objects, the ability to absorb light of different wavelengths is also different. Therefore, each object has a specific absorption spectrum. A spectrophotometer separates each monochromatic light from a mixture of wavelengths and measures its intensity.

A photoelectric sensor is a device that converts optical signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon of the corresponding electrical effect occurring when the electrons of the material absorb the energy of photons when light is irradiated on certain substances. According to the difference of photoelectric effect phenomenon, photoelectric effect is divided into three categories: external photoelectric effect, internal photoelectric effect and photovoltaic effect. Photoelectric devices include photocells, photomultipliers, photoresistors, photodiodes, phototransistors, and photocells.
