Kniel electrical components, German Kniel models, Kniel pricing

Kniel electrical components are resettable fuses that can be actuated multiple times, known in Japan as permanent fuses. Immediately after interrupting an overload or short-circuit current, the fusible element automatically returns to its original state. The housing is made of austenitic stainless steel, with a beryllium oxide ceramic core embedded in the center. The space between the stainless steel and the ceramic core is filled with glass to provide sealing and secure the ceramic core. The fine pores in the ceramic core are filled with metallic sodium as the fusible element, and the void behind the piston is charged with argon gas to compress the metallic sodium. Under normal operating conditions, current enters from lead terminal A, passes through the metallic sodium in the fine pores of the ceramic core, conducts to the stainless steel housing, and exits via output terminal B. When a short-circuit current flows through the fuse, it rapidly heats the metallic sodium in the fine pores of the ceramic core, causing it to change from a solid to a high-temperature, high-pressure plasma vapor. The resistivity increases rapidly, providing strong current-limiting action against the short-circuit current and interrupting the current instantly. At the end of the interruption, the sodium vapor immediately returns to liquid and solid states, while the argon gas pushes the piston again to compress the metallic sodium, re-establishing the circuit connection.

Kniel electrical component functions

(1) often compares sensor functions to the 5 major human sensory organs: photosensitive sensors for vision, acoustic sensors for hearing, gas-sensitive sensors for smell, chemical sensors for taste, and pressure-, temperature-, and fluid-sensitive sensors for touch. (2) Classification of sensitive elements: Physical type, based on physical effects such as force, heat, light, electricity, magnetism, and sound. Chemical type, based on the principles of chemical reactions. Biological type, based on molecular recognition functions such as enzymes, antibodies, and hormones. Typically, they are 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 49 categories).

Kniel electrical component features

Mercury switches achieve switching by moving mercury enclosed in a glass or metal housing. Therefore, compared with mechanical switches, mercury switches have many characteristics: (1) They can be used in harsh environmental conditions. Since the mercury switch is sealed, the internal mercury is isolated from the outside, allowing it to be used in environments with oil, steam, dust, and corrosive gases. (2) Low external force is required for switching. Mercury is the only metal that remains liquid at room temperature; it has high surface tension and specific gravity. A slight tilt caused by minimal external force moves the mercury, enabling the switch to open or close. (3) Mercury has good conductivity, and the contact resistance between the electrodes of a mercury switch is generally very low. (4) The allowable current of a mercury switch depends on the electrode material. (5) Since the switching of a mercury switch is determined by the gravity of the mercury, it can operate reliably over long periods. (6) The electrode contacts are liquid, producing no noise. (7) Because mercury can flow, the mercury switch can open or close as long as the acceleration exceeds a set value, allowing it to be used as a vibration-sensitive element. (8) Small size, diverse forms, and fully sealed construction. (9) Simple structure and low cost. (10) High quality and excellent products, suitable for beginners.
