infrarodon electrical component characteristics

The static characteristics of a sensor refer to the relationship between the output and input quantities for static input signals. 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 denote 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 for 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 changes continuously multiple times over the full scale in the same direction. (5) Drift: Sensor drift refers to the change in the sensor output over time while the input remains constant; this phenomenon is called drift. There are two causes of drift: one is the sensor's own structural parameters; 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-operating state for a long 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 operate. When the ambient temperature is the same, the operating time of the thermistor decreases sharply as the current increases; at relatively higher ambient temperatures, the thermistor has shorter operating times and lower holding and operating currents. The PTC effect is a material property known as the positive temperature coefficient effect, meaning that the resistance of the 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 temperature, which is commonly referred to as the linear PTC effect. Nonlinear PTC effect: Materials undergoing phase transitions exhibit a phenomenon where resistance increases abruptly by several to more than ten orders of magnitude within a narrow temperature range, known as the nonlinear PTC effect. Many types 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 and are often referred to as self-resetting fuses (hereinafter referred to as thermistors). Due to their unique positive temperature coefficient resistance characteristics, they are highly suitable as overcurrent protection devices. Thermistors are used in series in circuits, similar to ordinary fuses. When the circuit operates normally, the thermistor temperature is close to room temperature, and its resistance is very low, so it does not hinder current flow when connected in series. However, when an overcurrent occurs due to a fault, the thermistor's temperature rises due to increased heat generation. When the temperature exceeds the switching temperature, the resistance increases dramatically, rapidly reducing the current in the circuit to a safe value. After the thermistor operates, the current in the circuit drops significantly; t is the operating time of the thermistor. Due to the good designability of polymer PTC thermistors, their sensitivity to temperature can be adjusted by changing their switching temperature (ts), allowing them to provide both over-temperature and overcurrent protection. They are suitable for overcurrent and over-temperature protection of lithium-ion and nickel-metal hydride batteries. Influence of ambient temperature on polymer PTC thermistors: Polymer PTC thermistors are direct-heated, step-type thermistors. Their resistance change process is related to their own heat generation and dissipation conditions, so their holding current, operating current, and operating 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 ease of turn-off and the need for few 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" (in contrast 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.
