faber electrical components are transducers that convert guided waves propagating on transmission lines into electromagnetic waves propagating in an unbounded medium (usually free space), or perform the reverse conversion. They are components in radio equipment used to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, all rely on antennas for operation. In addition, for energy transmission using electromagnetic waves, non-signal energy radiation also requires antennas. General antennas possess reciprocity, meaning the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna for transmission or reception are identical. This is the antenna reciprocity theorem. As we know, radio equipment such as communication, radar, navigation, broadcasting, and television devices transmit information via radio waves and require the radiation and reception of radio waves. In radio equipment, the device used to radiate and receive radio waves is called an antenna. The antenna provides the necessary coupling between the transmitter or receiver and the medium propagating the radio waves. Like transmitters and receivers, the antenna is an important component of radio equipment.

faber electrical component characteristics

Resolution refers to the ability of a sensor to detect the smallest change in the measured quantity. That is, if the input changes slowly from a non-zero value, the sensor output will not change when the input change does not exceed a certain value; i.e., the sensor cannot resolve this change in the input. The output changes only when the input change exceeds the resolution. Typically, the resolution at various points within the full-scale range of a sensor is not identical; therefore, the maximum change in input within the full scale that causes a step change in the output is commonly used as the indicator for resolution. If the above indicator is expressed as a percentage of the full scale, it is termed resolution. Resolution has a negative correlation with sensor stability.

faber electrical component principles

The basic working principle of fiber optic sensors is to guide light from a source through an optical fiber into a modulator. The interaction between the parameter to be measured and the light entering the modulation zone causes changes in the optical properties of the light (such as intensity, wavelength, frequency, phase, polarization state, etc.), resulting in modulated signal light. Measurement is completed by utilizing the influence of the measured quantity on the light transmission characteristics. There are two measurement principles for fiber optic sensors: (1) Principle of intrinsic fiber optic sensors: Intrinsic fiber optic sensors utilize the sensitivity of the optical fiber to environmental changes to convert input physical quantities into modulated optical signals. Their working principle is based on the optical modulation effect of the fiber, i.e., the phenomenon where light transmission characteristics, such as phase and intensity, change when external environmental factors like temperature, pressure, electric field, and magnetic field change. Therefore, by measuring the changes in optical phase and intensity through the fiber, changes in the measured physical quantity can be determined. These sensors are also known as sensitive element type or functional fiber optic sensors. The point source beam of a laser is expanded into parallel waves and split by a beam splitter into two paths: one reference path and one measurement path. External parameters (temperature, pressure, vibration, etc.) cause changes in fiber length and optical phase, generating different numbers of interference fringes. Counting the lateral movement of these fringes allows measurement of temperature or pressure. (7) Principle of extrinsic fiber optic sensors: Extrinsic fiber optic sensors are measurement systems composed of optical detection elements (sensitive elements), fiber optic transmission circuits, and measurement circuits. Here, the optical fiber serves only as a light propagation medium, so they are also called non-functional or light-transmitting fiber optic sensors.
