2024-03-15 What is the principle of strain gauge? Strain Gauges is a sensor used to measure the strain generated when an object is stressed. Strain gauges are widely used in fields such as material mechanics, structural analysis, and pressure sensors. They have the characteristics of high precision, high sensitivity, and good stability. Common strain gauges include: resistance strain gauges, pressure strain gauges, fiber optic strain gauges, capacitive strain gauges, etc. The principle of strain gauge can be understood as the relationship between elastic deformation and resistance change. When an object is acted upon by an external force, the object will undergo elastic deformation, that is, the deformation will change with the action of the external force. At the same time, the resistor sheet is affected by deformation, and the resistance value will also change accordingly. This change can be measured and processed by accessing a circuit and connecting it to an electrical signal acquisition device to obtain the magnitude and nature of the force on the object. Its working principle also involves some physical principles, such as Hooke's law and strain-stress relationship. According to Hooke's law, the deformation of an elastic body is proportional to the force exerted on it. This relationship can be realized using strain gauges. The strain-stress relationship describes the relationship between the internal strain of an object and external forces. Strain gauges can indirectly obtain the stress on an object by measuring the strain value.

2024-03-08 What are the different types of load cells? Load Cells are a device used to measure and monitor the weight or mass of an object. They are widely used in industrial production, commercial retail, medical diagnosis, scientific experiments and other fields.

Pressure sensor: Uses the pressure exerted by an object on the sensor to measure the weight of an object. It has the advantages of simple structure and low cost. Resistive strain sensor: The force exerted by an object on the sensor is used to deform the strain gauge, thereby changing the resistance value of the sensor, thereby measuring the weight of the object. Capacitive weighing sensor: It has the advantages of simple structure and fast response speed, and is suitable for some fields that require high weighing response speed. When a force is applied to an object, the distance between the capacitors or the dielectric constant of the medium changes, thereby changing the capacitance value and thereby measuring the weight of the object. Magnetic induction load sensor: uses the weight of an object on the sensor to change the magnetic field inside the sensor to measure the weight of the object. Ultrasonic load cell: Calculate the weight of an object by measuring the propagation time of ultrasonic waves between the object and the sensor.

2024-02-29 How does load cell sensor work? Load cell sensor is a sensor device used to measure weight or mass, usually composed of a carrier, an elastomer and a sensing element. Its working principle is mainly based on the principles of elastic deformation and resistance change. First, when an object is placed on the sensor carrier, the carrier will undergo slight bending or compression deformation due to the gravity of the object. This deformation will be transmitted to the elastomer of the sensor, and the elastomer itself will have a certain deformation ability to adapt to the pressure of the object. Second, the elastomer is mounted with a sensing element, usually a resistance strain gauge or thin film sensor. When the elastomer deforms, the sensing element will also be affected and the resistance value will change. This change in resistance value can be converted into a voltage or current signal through a circuit, and then the final weight or mass value can be obtained through amplification, filtering, etc. In practical applications, load cells can output weight data by connecting to a display or controller, thereby achieving accurate measurement and monitoring of the weight of objects. Some common load cell types are: Resistive strain gauge load cell: Uses the resistive strain effect to measure the weight of an object. Commonly used ones include chip resistive strain gauge load cells and Beam Load Cells.

2021-10-29 How to install a load cell? How to install a load cell? The installation method of each load cell is unique because there are many types of sensors. When your application requires very high accuracy, long-term stability, custom specifications, or use in a changing R&D environment, please consult an engineer. In order to obtain accurate weighing results, please ensure that the load cell uses the specified weighing application. The load cell has a specified load direction, please do not apply lateral force, bending, or twisting motion on the load cell. Improper loading applications may reduce the life of the load cell and distort the correct measurement results. In pressure load applications, using a rigid design for the support structure of the load cell is better than a flexible design to achieve a uniform reduction of all supports. These supports can also distribute tension and provide a uniform contact surface. Mounting the load cell on the support structure and rigid substrate ensures that the load is evenly transferred from the bottom of the load cell to the support structure. The structure must also have the ability to support the force corresponding to the load. In order to comply with the installation of the load cell, it may be necessary to install auxiliary tools. You can ask the design engineer for help to determine the weight of each interference possibility. Special consideration needs to be given to weighing tanks, thermal expansion, monitoring levels, and horizontal movement of certain tank shapes and supporting structures to avoid measurement distortion. Your load cell support structure may require end stops to limit lateral deflection, and elastic bearings can also adjust the heat between the storag

The load cell is a conversion device used to convert a weight signal or a pressure signal into a power signal. The construction principle of the load cell is that the metal resistance has the property of obstructing the flow of current. Generally speaking, the more slender the metal

2021-08-18 The history of scales The history of scales If you go back in time and show an old street merchant a digital scale, he will not know what to do. However, throughout history, the importance of scale to the economy is as important as it is today, which is why people have been working hard - and continuing to work - to obtain more accurate measurement results. Ancient survey Distance Before the advent of standardized equipment, many measurements were based on a certain part of the body, such as the hands or feet-hence the "foot" of the Americans. When the standard ruler was introduced, these measurements became more accurate. Then, a known, repeatable standard will serve a specific geographic area. Later, the two parties reached an agreement to produce a standard metal rod with two marks, which was very carefully made. This distance is designed to represent a fraction of one-tenth of the distance from the equator to the North Pole. Recently, however, the definition of meters has become more accurate. It is defined as the distance that light travels in a specific, very small second. This distance is very standard and can be reproduced anywhere. Time Similarly, with the development of history, the measurement of time has become more accurate. The earliest measurements are based on the length of a day, or the amount of time between sunrise and sunset. The invention of the sundial has achieved higher accuracy, which can divide the day into multiple parts. The specially manufactured candles are designed to burn at a steady rate, which provides a more accurate method of timekeeping. Hourglas
