SAPISELCO electrical components Germany SAPISELCO model SAPISELCO price

SAPISELCO electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of fiber optic sensors is to guide the light beam from the light source into a modulator via an optical fiber. 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 guided through the optical fiber, passes through the modulator, and is emitted, where the role of the optical fiber is first to transmit the light beam and second to act as an optical modulator.

SAPISELCO electrical components principle

A resistor consists of three parts: the resistive element, the substrate, and the leads (in solid-core resistors, the resistive element and substrate are combined), but only the resistive element determines the resistance value. The volt-ampere characteristic is represented by a graphical curve showing the relationship between voltage and current at the resistor terminals. When voltage and current are proportional (the characteristic is a straight line), it is called a linear resistor; otherwise, it is called a non-linear resistor. The maximum power allowed to be dissipated continuously by the resistor at the rated temperature (maximum ambient temperature) tR. For each type of resistor, a maximum operating voltage is also specified; that is, even if the rated power is not reached, the maximum operating voltage must not be exceeded when the resistance value is high. The rated power of a resistor refers to the maximum power allowed to be consumed during long-term continuous operation in DC or AC circuits. Load characteristics: When the ambient temperature is lower than tR, the resistor must not exceed its rated power; when it exceeds tR, the load power must be reduced. Each type of resistor has specified load characteristics. In addition, the allowable load is correspondingly reduced under low atmospheric pressure. Under pulse load conditions, the average pulse power is much lower than the rated power, and separate specifications generally apply.
