infrarodon electrical component characteristics

The static characteristics of a sensor refer to the relationship between the output and input quantities for a static input signal. Since the input and output quantities are independent of time in this case, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input quantity as the abscissa and the corresponding output quantity as the ordinate. The main parameters characterizing the static characteristics of a sensor include: linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: refers to the degree to which the actual relationship curve between the sensor output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted straight line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of the static characteristics of a sensor. It is defined as the ratio of the increment in the output quantity to the corresponding increment in the input quantity that causes this increment. S is used to represent sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide when the input quantity changes from small to large (forward stroke) and from large to small (reverse stroke). For the same magnitude of input signal, the output signals of the sensor during the forward and reverse strokes are not equal; this difference is called the hysteresis error. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor input quantity undergoes continuous multiple full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor output changes over time while the input quantity remains constant. There are two main causes of drift: one is the structural parameters of the sensor itself; the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor input increases slowly from a non-zero value, an observable change in the output occurs after exceeding a certain increment; this input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor input increases slowly from zero, an observable change in the output occurs after reaching a certain value; this input value is called the sensor's threshold voltage.

infrarodon electrical component principles

The thermistor will remain in a non-tripped state for an extended period; When the ambient temperature and current are in the c region, the heat dissipation power of the thermistor is close to its heat generation power, so it may or may not trip. For a thermistor at the same ambient temperature, the tripping time decreases sharply as the current increases; At relatively higher ambient temperatures, the thermistor has a shorter tripping time and lower holding and tripping currents. The PTC effect refers to a material exhibiting the PTC effect, namely the positive temperature coefficient effect, meaning that the resistance of this material increases with rising temperature. For example, most metallic materials exhibit the PTC effect. In these materials, the PTC effect manifests as a linear increase in resistance with increasing temperature, which is commonly referred to as the linear PTC effect. Nonlinear PTC effect: Materials undergoing a phase transition exhibit a phenomenon where resistance increases sharply by several to more than ten orders of magnitude within a narrow temperature range, known as the nonlinear PTC effect. A considerable variety of conductive polymers exhibit this effect, such as polymer PTC thermistors. These conductive polymers are very useful for manufacturing overcurrent protection devices. Polymer PTC thermistors are used for overcurrent protection. Polymer PTC thermistors are often referred to as resettable fuses (hereinafter referred to as thermistors), Due to their unique positive temperature coefficient resistance characteristics, they are highly suitable for use as overcurrent protection devices. The method of using a thermistor is similar to that of a conventional fuse, It is used in series in the circuit. When the circuit is operating normally, the thermistor temperature is close to ambient temperature and the resistance is very low, so being in series in the circuit does not impede current flow; however, when an overcurrent occurs in the circuit due to a fault, the thermistor temperature rises due to increased heating power, and when the temperature exceeds the switching temperature, the resistance increases sharply in an instant, and the current in the loop rapidly decreases to a safe value. After the thermistor trips, the current in the circuit is significantly reduced, t is the tripping time of the thermistor. Due to the good design flexibility of polymer PTC thermistors, their temperature sensitivity can be adjusted by changing their own switching temperature (ts), thus providing both over-temperature protection and over-current protection simultaneously, making them suitable for over-current and over-temperature protection of lithium-ion batteries and nickel-metal hydride batteries. Influence of ambient temperature on polymer PTC thermistors: A polymer PTC thermistor is a directly heated, step-type thermistor, whose resistance change process is related to its own heat generation and dissipation conditions, therefore its holding current, tripping current, and tripping time are influenced by ambient temperature.

infrarodon electrical component functions

Control high power, capable of controlling hundreds of kilowatts. Using power transistors as switches has many advantages, primarily easy turn-off and few required auxiliary components. Fast switching allows operation at high frequencies. Transistor compounding (Darlington) and parallel connection are effective methods to increase transistor switching capability. In such high-power circuits, the main problem is wiring. High switching speeds can generate significant interference voltages even on short connection lines. Simple and optimized base drive achieves high performance. The base drive circuit not only drives the power transistor but also protects it, referred to as "decentralized protection" (as opposed to centralized protection). Functions of integrated drive circuits include: turning on and off the power switch, monitoring auxiliary power supply voltage, limiting maximum and minimum pulse widths, thermal protection, and monitoring the switch's saturation voltage drop.
