ge consumer electrical components are sensor resistors whose resistance changes with temperature. Based on different temperature coefficients, they are classified into positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. The resistance of PTC thermistors increases as temperature rises, while the resistance of NTC thermistors decreases as temperature rises; both belong to semiconductor devices.

A fuel cell is an energy conversion device that operates on electrochemical principles, specifically the working principle of a primary battery, isothermally converting the chemical energy stored in fuel and oxidant directly into electrical energy; thus, the actual process is an oxidation-reduction reaction. A fuel cell mainly consists of four parts: the anode, cathode, electrolyte, and external circuit. Fuel gas and oxidizing gas are introduced through the anode and cathode of the fuel cell, respectively. The fuel gas releases electrons at the anode; these electrons are conducted through the external circuit to the cathode, where they combine with the oxidizing gas to form ions. Under the influence of the electric field, the ions migrate through the electrolyte to the anode, react with the fuel gas, complete the circuit, and generate current. Meanwhile, due to the electrochemical reaction itself and the internal resistance of the battery, the fuel cell also generates a certain amount of heat. In addition to conducting electrons, the cathode and anode also serve as catalysts for the oxidation-reduction reaction. When the fuel is a hydrocarbon, the anode requires higher catalytic activity. The cathode and anode are typically porous structures to facilitate the introduction of reactant gases and the discharge of products. The electrolyte serves to transmit ions and separate the fuel gas from the oxidizing gas. To prevent the mixing of the two gases, which would cause a short circuit within the battery, the electrolyte is typically a dense structure. The composition of a fuel cell is the same as that of a general battery. Its single cell consists of two electrodes (negative electrode, i.e., fuel electrode, and positive electrode, i.e., oxidant electrode) and an electrolyte. The difference is that the active materials of a general battery are stored inside the battery, thus limiting the battery capacity. In contrast, the positive and negative electrodes of a fuel cell do not contain active materials themselves but are merely catalytic conversion elements. Therefore, a fuel cell is truly an energy conversion machine that converts chemical energy into electrical energy. During operation, fuel and oxidant are supplied externally for the reaction. In principle, as long as reactants are continuously input and reaction products are continuously removed, the fuel cell can generate electricity continuously.

A potentiometric displacement sensor converts mechanical displacement into a resistance or voltage output that has a linear or arbitrary functional relationship with the displacement via a potentiometer element. Ordinary linear potentiometers and circular potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, potentiometers designed for the purpose of measuring displacement require a definite relationship between displacement change and resistance change. The movable wiper of the potentiometric displacement sensor is connected to the object being measured. The displacement of the object causes a resistance change at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while whether the resistance increases or decreases indicates the direction of the displacement. Typically, a power supply voltage is applied across the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps based on the turn-to-turn resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement sensor is used as a displacement feedback element in a servo system, excessive step voltages may cause system oscillation. Therefore, the resistance value per turn should be minimized during the manufacture of the potentiometer. Another major disadvantage of potentiometric sensors is their susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost.

ge consumer electrical component characteristics

The static characteristics of a sensor refer to the relationship between the output quantity and the input quantity 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's 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 a sensor's static characteristics. It is defined as the ratio of the increment in the output quantity to the corresponding increment in the input quantity that causes it. Use S 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 input quantity undergoes continuous multiple full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor's output changes over time while the input quantity remains constant. 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's input slowly increases from a non-zero value, an observable change in 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's input slowly increases from zero, an observable change in output occurs after reaching a certain value; this input value is called the sensor's threshold voltage.
