beurer electrical components are Schottky barrier diodes named after their inventor, Dr. Schottky. Schottky barrier diodes are not made using the principle of forming a PN junction by contact between P-type semiconductor and N-type semiconductor, but rather using the principle of a metal-semiconductor junction formed by contact between metal and semiconductor. Therefore, Schottky barrier diodes are also called metal-semiconductor (contact) diodes or surface barrier diodes; they are a type of hot-carrier diode.

beurer electrical component principle

Mainly consists of an LC circuit composed of capacitors and inductors, generating free oscillation through the mutual conversion of electric field energy and magnetic field energy. To sustain oscillation, an amplifier circuit with positive feedback is also required. LC oscillators are further divided into transformer-coupled and three-point oscillators. Many applications use quartz crystal oscillators with quartz crystals, and there are also LC oscillators composed of integrated operational amplifiers. Since device parameters cannot be completely identical, the states of the two transistors change at the moment of power-on. This change becomes increasingly strong due to positive feedback, leading to a quasi-stable state. During the quasi-stable state, the other transistor gradually charges via the capacitor and then conducts or cuts off, causing the state to flip and reach another quasi-stable state. This cycle repeats to form oscillation.

beurer electrical component principle

The absorption film irradiated by infrared rays is a thin film with low heat capacity and easy temperature rise. A cavity structure is located directly below the center of the substrate. This design ensures a temperature difference between the cold end and the measuring end. The thermocouple is composed of polysilicon and aluminum, connected in series. When the temperature at the measuring end of each thermocouple rises, a thermoelectromotive force Vn is generated between the thermocouples, so the sum of their voltages can be obtained at the output terminal.
