BEGBRUCK electrical components Germany BEGBRUCK model BEGBRUCK price

BEGBRUCK electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from a light source via an optical fiber into a modulator. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is introduced via the optical fiber, passes through the modulator, and is then emitted. The role of the optical fiber is first to transmit the light beam, and second, to act as an optical modulator.

Most microphones are electret condenser microphones (ECM), a technology with a history spanning several decades. The working principle of ECM utilizes a polymer diaphragm with permanently isolated charge. Compared to the polymer diaphragm of ECM, MEMS microphones exhibit stable performance across different temperatures and are unaffected by temperature, vibration, humidity, or time. Due to strong heat resistance, MEMS microphones can withstand high-temperature reflow soldering without any change in performance. Since the sensitivity change before and after assembly is minimal, this can even save audio debugging costs during the manufacturing process. Currently, integrated circuit processes are increasingly widely applied in the manufacture of sensors and sensor interface integrated circuits. This microfabrication process offers advantages such as precision, design flexibility, miniaturization, integration with signal processing circuits, low cost, and mass production. A fundamental resonant frequency in such a low frequency range would result in highly uneven frequency response within the audible frequency range for the microphone, which is unacceptable for microphone applications. When tensile stress exists within the sensitive membrane, its resonant frequency increases, but at the cost of sensitivity. Of course, higher fundamental resonant frequencies can be achieved by adjusting the dimensions of the sensitive membrane, but this will still reduce sensitivity. Thus, piezoresistive schemes are not suitable for the manufacture of miniature microphones. A feasible solution is to adopt a capacitive scheme for manufacturing miniature microphones. The advantage of this method is that all materials used in integrated circuit manufacturing processes can be utilized for sensor fabrication. However, manufacturing micro-microphones using single-chip processes is quite difficult because the air gap between the two capacitor plates can only be very small. Moreover, due to size limitations, bias voltage is difficult to satisfy in some application scenarios. Due to these issues, research on capacitive microphones has continued uninterrupted. Compared to traditional electret microphones, micro-electromechanical system (MEMS) microphones offer advantages such as small size, good heat resistance, good consistency, good stability, high reliability, and resistance to radio frequency interference. They can also output digital signals, facilitating intelligent development.

They can serve as human eyes and ears in places inaccessible to humans (such as high-temperature areas or areas harmful to humans, such as nuclear radiation zones), and can even surpass human physiological limits, receiving external information imperceptible to human senses.

BEGBRUCK electrical component parameters

The main characteristic parameters of quartz crystal resonators include nominal frequency, adjustment frequency deviation, temperature frequency deviation, equivalent resistance, drive level, load capacitance, shunt capacitance, aging rate, and temperature range. (1) Nominal frequency is the specified resonant center frequency of the resonator under prescribed conditions. (2) Adjustment frequency deviation is the maximum deviation of the operating frequency from the nominal frequency at the reference temperature under prescribed conditions. (3) Temperature frequency deviation is the allowable deviation from the operating frequency at the reference temperature over the entire operating temperature range under prescribed conditions. (4) Reference temperature is the specified ambient temperature when measuring quartz crystal resonator parameters. For oven-controlled quartz crystal resonators, it is generally the center point of the operating temperature range; (5) Load resonance resistance is the resistance value at the load resonance frequency when the quartz crystal resonator is connected in series with a specified external capacitance. (6) Drive level refers to the effective power consumed by the quartz crystal resonator during operation; it is a measure of the excitation state applied to the quartz crystal element. In actual use, the drive level can be adjusted; strong excitation makes oscillation easier to start, while weak excitation leads to poor frequency stability, or even failure to oscillate. (7) Load capacitance refers to the effective external capacitance that, together with the quartz crystal resonator, determines the load resonance frequency. Load capacitance can be appropriately adjusted according to specific circumstances; generally, adjusting it allows tuning the resonator's operating frequency to the nominal value. (8) Shunt capacitance refers to the static capacitance between the two pins of the quartz crystal resonator. (9) Aging rate refers to the error generated by quartz crystal aging changes over time. (10) Temperature range refers to the allowable variation range of the ambient temperature during operation.
