GOSSEN Metrawatt electrical components are linear devices based on metallic induction. The function of a sensor is to convert various measured physical quantities into electrical signals. In production processes, displacement measurement is generally divided into two types: measuring physical dimensions and measuring mechanical displacement. Depending on the form of transformation of the measured variable, displacement sensors can be classified into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are predominantly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, and Hall effect displacement sensors. A major advantage of digital displacement sensors is that they facilitate direct input of signals into computer systems. Displacement is a quantity related to the movement of an object's position during motion, and the scope of displacement measurement methods is quite extensive. Small displacements are typically detected using strain gauge, inductive, differential transformer, eddy current, and Hall effect sensors. Large displacements are commonly measured using sensing technologies such as induction synchronizers, optical gratings, capacitive gratings, and magnetic gratings. Among these, optical grating sensors are increasingly widely used in industries such as machine tool machining and testing instruments due to advantages such as ease of digitization, high precision (with current highest resolution reaching the nanometer level), strong anti-interference capability, absence of human reading errors, convenient installation, and reliable operation.

GOSSEN Metrawatt electrical component principles

The main principle of a diode is to utilize the unidirectional conductivity of the PN junction. Adding leads and encapsulation to the PN junction forms a diode. A crystal diode consists of a PN junction formed by P-type semiconductor and N-type semiconductor. A space charge layer is formed on both sides of the interface, establishing a built-in electric field. When no external voltage is applied, the diffusion current caused by the carrier concentration difference across the PN junction equals the drift current caused by the built-in electric field, resulting in an electrical equilibrium state. When a forward voltage bias is applied externally, the mutual cancellation between the external electric field and the built-in electric field increases the diffusion current of carriers, causing a forward current. When a reverse voltage bias is applied externally, the external electric field and the built-in electric field are further strengthened, forming a reverse saturation current within a certain reverse voltage range that is independent of the reverse bias voltage value. When the applied reverse voltage reaches a certain level, the electric field strength in the space charge layer of the PN junction reaches a critical value, triggering a carrier multiplication process that generates a large number of electron-hole pairs, resulting in a significant reverse breakdown current, known as the diode breakdown phenomenon. Reverse breakdown of the PN junction is categorized into Zener breakdown and avalanche breakdown.

GOSSEN Metrawatt electrical component principles

A diesel engine drives the generator to operate, converting the energy of diesel into electrical energy. Inside the diesel engine cylinder, clean air filtered through the air filter mixes thoroughly with high-pressure atomized diesel injected by the fuel nozzle. Under the compression of the upward-moving piston, the volume decreases, and the temperature rises rapidly to reach the ignition point of diesel. The diesel ignites, causing intense combustion of the mixed gas, rapid volume expansion, and pushing the piston downward, referred to as "power stroke." A gasoline engine drives the generator to operate, converting the energy of gasoline into electrical energy. Inside the gasoline engine cylinder, the mixed gas burns intensely, expands rapidly in volume, and pushes the piston downward to perform work. Whether it is a diesel generator or a gasoline generator, each cylinder performs work sequentially in a specific order. The thrust acting on the piston is converted into force driving the crankshaft rotation via the connecting rod, thereby rotating the crankshaft. By mounting a brushless synchronous AC generator coaxially with the prime mover's crankshaft, the rotation of the prime mover drives the generator rotor. Based on the principle of 'electromagnetic induction,' the generator outputs induced electromotive force, generating current through a closed load circuit.

GOSSEN Metrawatt electrical component classification

Self-inductance occurs when current flowing through a coil generates a magnetic field around it. When the current in the coil changes, the surrounding magnetic field changes correspondingly. This changing magnetic field induces an electromotive force (induced EMF) in the coil itself (EMF represents the terminal voltage of an ideal power source for active components), which is known as self-inductance. An electronic component made by winding wire with a specific number of turns, capable of producing a certain amount of self-inductance or mutual inductance, is commonly called an inductor coil. To increase inductance, improve the quality factor, and reduce size, a core made of ferromagnetic material, such as an iron core or magnetic core, is often added. Basic parameters of an inductor include inductance, quality factor, inherent capacitance, stability, rated current, and operating frequency. An inductor composed of a single coil is called a self-inductor, and its self-inductance is also referred to as the self-inductance coefficient. Mutual inductance occurs when two inductor coils are placed close to each other; a change in the magnetic field of one coil affects the other. This influence is known as mutual inductance. The magnitude of mutual inductance depends on the self-inductance of the coils and the degree of coupling between them. Components manufactured based on this principle are called mutual inductors.
