EZ AUTOMATION electrical components, German EZ AUTOMATION models, EZ AUTOMATION prices

EZ AUTOMATION electrical components are linear devices based on metallic induction. The role 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 as analog or digital. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are mostly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, and Hall effect displacement sensors. An important 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 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 processing and testing instruments due to their advantages, including 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.

EZ AUTOMATION electrical component characteristics

So-called dynamic characteristics refer to the output behavior of a sensor when the input changes. In practical applications, the dynamic characteristics of a sensor are often expressed by its response to certain standard input signals. This is because the sensor's response to standard input signals is easily obtained through experimental methods, and there is a certain relationship between its response to standard input signals and its response to arbitrary input signals; often, knowing the former allows inference of the latter. The most commonly used standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of sensors are also commonly expressed by step response and frequency response.

EZ AUTOMATION electrical component principles

Based on different application purposes, various types of thermometers have been designed and manufactured. The design principles include: utilizing the thermal expansion and contraction of solids, liquids, and gases under temperature influence; the variation in pressure of gas (or vapor) at constant volume due to temperature differences; the thermoelectric effect; the variation of electrical resistance with temperature; and the influence of thermal radiation. 1. Gas thermometers: Hydrogen or helium is often used as the temperature-sensing medium because their liquefaction temperatures are very low, close to absolute zero, resulting in a wide measurement range. These thermometers offer high accuracy and are commonly used for precision measurements. 2. Resistance thermometers: Classified into metal resistance thermometers and semiconductor resistance thermometers, both are made based on the characteristic that resistance changes with temperature. Metal thermometers primarily use pure metals such as platinum, gold, copper, and nickel, as well as rhodium-iron and phosphor bronze alloys; semiconductor thermometers mainly use carbon, germanium, etc. Resistance thermometers are convenient, reliable, and widely applied. 3. Thermocouple thermometers: A type of temperature-measuring instrument widely used in industry. They are made using the thermoelectric effect. Two different metal wires are welded together to form the measuring junction, while the other ends are connected to a measuring instrument to form a circuit. When the measuring junction is placed at the temperature to be measured, a difference in temperature between the measuring junction and the reference junction generates an electromotive force, causing current to flow through the loop. By measuring electrical quantities and knowing the temperature at one point, the temperature at the other point can be determined. It is suitable for applications involving significant temperature differences between two substances and is often used for high-temperature and low-temperature measurements. 4. Dial thermometers: These are dashboard-shaped thermometers, also known as room thermometers, used to measure ambient temperature. They operate on the principle of thermal expansion and contraction of metals. They use a bimetallic strip as the sensing element to control the pointer. The bimetallic strip is typically made by riveting a copper strip and an iron strip together, with the copper strip on the left and the iron strip on the right. Since copper exhibits significantly more thermal expansion and contraction than iron, when the temperature rises, the copper strip pulls the iron strip to bend to the right, causing the pointer to deflect to the right (indicating high temperature); conversely, when the temperature drops, the pointer deflects to the left under the drive of the bimetallic strip. 5. Glass tube thermometers: Glass tube thermometers utilize the principle of thermal expansion and contraction to measure temperature. Due to differences in the expansion coefficients, boiling points, and freezing points of the sensing media, common glass tube thermometers mainly include kerosene thermometers, mercury thermometers, and red ink thermometers. Their advantages are simple structure, ease of use, relatively high measurement accuracy, and low cost. The disadvantages are that the measurement range and accuracy are limited by the quality of the glass and the properties of the sensing medium. Additionally, they cannot transmit signals over long distances and are fragile. 6. Pressure thermometers: Pressure thermometers use the volume expansion or pressure change of liquid, gas, or saturated vapor in a sealed container upon heating as the measurement signal. Its basic structure consists of three parts: a temperature bulb, a capillary tube, and an indicator gauge. The advantages of pressure thermometers are: simple structure, high mechanical strength, and resistance to vibration. They are low-cost and do not require an external power source. The disadvantages are: limited temperature measurement range; significant heat loss and slow response time. 16. Mercury thermometers are a type of expansion thermometer and can only be used as local monitoring instruments. Using them to measure temperature is not only simple and intuitive but also helps avoid errors associated with remote transmission thermometers.

EZ AUTOMATION electrical component functions

① Sensor functions are often compared to the 5 major sensory organs of humans: photosensitive sensors - vision, acoustic sensors - hearing, gas-sensitive sensors - smell, chemical sensors - taste, and pressure-sensitive, temperature-sensitive, and fluid sensors - touch. ② Classification of sensitive elements: Physical category, based on physical effects such as force, heat, light, electricity, magnetism, and sound. Chemical category, based on the principles of chemical reactions. Biological category, based on molecular recognition functions such as enzymes, antibodies, and hormones. Typically, based on their basic sensing functions, they can be divided into ten major categories: thermal-sensitive elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic-sensitive elements, humidity-sensitive elements, acoustic-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements (some have also classified sensitive elements into 49 categories).
