R-type thermocouples can measure high temperatures of more than 1700 degrees, and are mainly used in high temperature measurement occasions. In today's article, let's talk about how thermocouples work.

    Radiation Sensor Working Principle

    Radiation sensor works by measuring the number of small units of light, known as photons that impact a physical or chemical device located within the instrument. Solar radiation sensors are typically not powered due to the fact that the components located in the device either are influenced by or react to solar radiation in a direct manner.

    Miniature Circuit Breaker Working Principle

    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.

It has the characteristics of small lifting weight, simple result and convenient operation, and is widely used in the installation, lifting and maintenance of small equipment in industrial and mining enterprises. Generally, electrical power chain hoists have only one constant running speed.

    Centrifugal Pump: How Does it Work?

    Centrifugal pump refers to a pump that transports liquid by the centrifugal force generated by the rotation of the impeller. Centrifugal pumps are widely used and are almost indispensable equipment in process systems. The small size, simple operation and long service life of the centrifugal pump are the outstanding advantages of the centrifugal pump. If the pipeline delivery system is regarded as the vascular circulation system of the human body, then the centrifugal pump is equivalent to the heart that transports blood.

    Dosing Pump Working Principle

    The working principle of dosing pump is relatively simple, but because it involves highly corrosive liquid and high-precision flow, it has very high requirements for every part and every process of the machine. When the coil of the electromagnet is charged, the iron core pulls the electromagnetic push rod together, and at the same time, the corresponding five springs are compressed and the liquid is quantitatively sucked in. And when the coil of the electromagnet loses power, due to the disappearance of the electromagnetic force, the compressed 5 springs will be released, so that the liquid is quantitatively discharged.

    DC-DC Converter Working Principle

    The DC-DC converter is a voltage converter that effectively outputs a fixed voltage after converting the input voltage. DC to DC converters are divided into three categories: step up DC-DC converters, step down DC- DC converters, and buck-boost DC-DC converters. Three types of controls can be used according to requirements. At present, DC to DC converters are widely used in products such as mobile phones, MP3s, digital cameras, and portable media players.

    What is a Temperature Controller?

    The temperature controller is a kind of intelligent temperature control instrument. It has the functions of temperature curve programmable or fixed-point constant temperature control, multiple PID regulation, output power limiting curve programming, manual / automatic switching, soft start, alarm switch output, real-time data query, communication with computer, etc. It combines digital temperature meter and ZK thyristor voltage regulator into one, which integrates temperature measurement, regulation and driving. The meter directly outputs thyristor trigger signal, which can drive all kinds of thyristor loads. It is used in all kinds of high and low voltage switchgear, dry-type transformer, box type substation and other related temperature application fields. In addition to understanding what the temperature controller is, we also need to know its three "how": how to work, how to use, and how to choose the temperature controller for better use of ATO.
