PAVONE SISTEMI electrical components are devices for detachable (active) connection between optical fibers. They precisely align the end faces of two optical fibers to maximize the coupling of light energy from the transmitting fiber into the receiving fiber, and minimize the impact on the system caused by their insertion into the optical link. This is the basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and various performance metrics of optical transmission systems.

PAVONE SISTEMI electrical component structure

Common electrodynamic cone paper-cone loudspeakers. Electrodynamic cone loudspeakers were formerly known as paper-cone loudspeakers; although the diaphragm is still primarily made of paper cone, many polymer material diaphragms and metal diaphragms have emerged, making the term cone loudspeaker more accurate. A cone paper-cone loudspeaker mainly consists of three parts: the magnetic circuit system (permanent magnet, pole piece, magnetic plate), the vibration system (paper cone, voice coil), and the support auxiliary system (spider, basket, surround). 1. Voice coil: The voice coil is the drive unit of the cone paper-cone loudspeaker. It is made of very fine copper wire wound in two layers around a paper tube, typically with dozens of turns, also known as a coil. It is placed in the magnetic gap formed by the magnetic pole piece and the magnetic plate. The voice coil is fixed to the paper cone. When an audio current signal passes through the voice coil, the vibration of the voice coil drives the paper cone to vibrate. 2. Paper cone: There are many types of materials used for the cone diaphragm of cone paper-cone loudspeakers, generally divided into natural fibers and synthetic fibers. Natural fibers often include cotton, wood, wool, silk, etc., while synthetic fibers include rayon, nylon, fiberglass, etc. As the paper cone is the sound radiation component of the loudspeaker, it largely determines the acoustic performance. Therefore, regardless of the type of paper cone, it must be lightweight and rigid, and must not deform due to changes in ambient temperature or humidity. 3. Surround: The surround is designed to ensure axial movement of the paper cone along the loudspeaker axis and restrict lateral movement, while also preventing air leakage between the front and rear of the paper cone. In addition to materials commonly used for paper cones, surrounds may use plastics, natural rubber, etc., bonded to the paper cone via hot pressing. 12. Spider: The spider supports the junction between the voice coil and the paper cone, ensuring it remains vertical and not skewed. The spider has many concentric rings that allow the voice coil to move freely up and down in the magnetic gap without lateral movement, ensuring the voice coil does not touch the magnetic plate. The dust cap on the spider prevents external dust from entering the magnetic gap, avoiding friction between dust and the voice coil that could cause abnormal sounds in the loudspeaker. Generally, a loudspeaker consists of a magnet, frame, spider, molded surround, and cone paper cone.

PAVONE SISTEMI electrical component applications

Thermistors can also be used as electronic circuit components for temperature compensation in instrument circuits and cold-junction temperature compensation for thermocouples. Utilizing the self-heating characteristics of NTC thermistors enables automatic gain control, forming RC oscillator amplitude stabilization circuits, delay circuits, and protection circuits. When the self-heating temperature is much higher than the ambient temperature, the resistance is also related to the heat dissipation conditions of the environment. Therefore, this characteristic of thermistors is often utilized in anemometers, flow meters, gas analyzers, and thermal conductivity analysis to create specialized detection elements. PTC thermistors are mainly used for overheat protection of electrical equipment, contactless relays, constant temperature control, automatic gain control, motor starting, time delay, automatic degaussing of color TVs, fire alarms, and temperature compensation. Main disadvantages: (1) severe nonlinearity in the relationship between resistance and temperature; (2) poor consistency and interchangeability of components; (3) components are prone to aging and have poor stability; (4) except for special high-temperature thermistors, most thermistors are only suitable for the range of 0 to 155 °C, which must be noted during use.

PAVONE SISTEMI electrical component characteristics

Under normal circumstances, the actual static output characteristic of a sensor is a curve rather than a straight line. In practical work, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximately represent the actual characteristic curve. Linearity (nonlinear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero input and full-scale output points can be used as the fitted straight line; or the theoretical straight line that minimizes the sum of squared deviations from each point on the characteristic curve can be used as the fitted straight line, known as the least squares fitted straight line.
