COREX electrical components Germany COREX model COREX price

COREX electrical components are commonly used temperature-sensing elements in temperature measurement instruments. They directly measure temperature and convert the temperature signal into a thermoelectric EMF signal, which is then converted into the temperature of the measured medium by an electrical instrument (secondary instrument). The external shapes of various thermocouples often differ significantly depending on requirements, but their basic structures are largely similar, typically consisting of main components such as hot electrodes, insulating protective tubes, and terminal blocks. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators. In industrial production processes, temperature is one of the important parameters that need to be measured and controlled. In temperature measurement, thermocouples are widely applied due to many advantages, including simple structure, ease of manufacturing, wide measurement range, high accuracy, low inertia, and output signals suitable for long-distance transmission. Additionally, since a thermocouple is a passive sensor that does not require an external power supply during measurement, it is very convenient to use and is often employed to measure the temperature of gases or liquids inside furnaces and pipes, as well as the surface temperature of solids.

COREX electrical components function

Control high power, capable of controlling hundreds of kilowatts of power. Using power transistors as switches has many advantages, primarily easy turn-off and few required auxiliary components. Fast switching allows operation at high frequencies. Transistor compounding (Darlington) and parallel connection are effective methods to increase transistor switching capability. In such high-power circuits, the main problem is wiring. High switching speeds can generate significant interference voltage even on short connection lines. Simple and optimized base drive achieves high performance. The base drive circuit not only drives the power transistor but also protects it, referred to as "decentralized protection" (in contrast to centralized protection). Functions of integrated drive circuits include: turning on and off the power switch, monitoring auxiliary power supply voltage, limiting maximum and minimum pulse width, thermal protection, and monitoring the switch's saturation voltage drop.

COREX electrical components utility

A multimeter can not only measure the resistance of the object under test, but also AC and DC voltages, including DC voltage. Some multimeters can even measure key parameters of transistors and the capacitance of capacitors. Proficient mastery of multimeter usage is one of the most basic skills in electronic technology. Common multimeters include analog multimeters and digital multimeters. An analog multimeter is a multifunctional measuring instrument with a meter head as its core component; the measured value is read from the pointer indication. The measured value of a digital multimeter is directly displayed in numerical form on an LCD screen, making it easy to read; some models also feature voice prompts. A multimeter is an instrument that integrates a voltmeter, ammeter, and ohmmeter using a common meter head. The DC current range of a multimeter is a multi-range DC ammeter. Connecting shunt resistors in parallel with the meter head expands its current range. The DC voltage range of a multimeter is a multi-range DC voltmeter. Connecting divider resistors in series with the meter head expands its voltage range. Different divider resistors correspond to different ranges. The meter head of a multimeter is a magnetoelectric measuring mechanism that can only pass DC. Diodes are used to convert AC to DC, thereby enabling AC measurement.

(1) often compares sensor functions to the human 5 major sensory organs: photosensitive sensors - vision, acoustic sensors - hearing, gas-sensitive sensors - smell, chemical sensors - taste, pressure-sensitive, temperature-sensitive, and fluid sensors - touch. (2) Classification of sensitive elements: Physical category, based on physical effects such as force, heat, light, electricity, magnetism, and sound. Chemical category, based on the principles of chemical reactions. Biological category, based on molecular recognition functions such as enzymes, antibodies, and hormones. Typically, they can be divided into ten major categories based on their basic sensing functions: thermal-sensitive elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic-sensitive elements, humidity-sensitive elements, acoustic-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements (some have also classified sensitive elements into 48 categories).
