 A voltage transducer is a device used to measure the voltage value in a circuit. It can convert the voltage signal to be detected into a signal (such as current, voltage, or frequency) that has a certain relationship with it and is easy to measure and process according to a specific ratio, thereby enabling accurate voltage monitoring. It is widely used in industrial automation, power systems, electronic equipment testing, new energy vehicles, and other fields. What are the main categories of voltage transducers? There are many types of voltage transducers . The following is divided according to the measured voltage type, sensing technology, and output signal type. Division of measured voltage type According to the measurement of different voltage types, it can be divided into DC voltage transducers, commonly used in battery systems, solar energy, and electric vehicles, and AC voltage transducers, used in power grids, industrial equipment, and household appliances. According to sen...

Hall effect current transducers are usually composed of Hall elements (a semiconductor material), magnetic circuits, and signal conditioning circuits. There are two main types of Hall effect current transducers : open-loop and closed-loop. They are widely used in power monitoring, motor control, and circuit protection. Principle of Hall Effect The Hall effect is a physical phenomenon caused by the interaction between current and magnetic field. When current passes through a conductor perpendicular to an external magnetic field, a potential difference, namely the Hall voltage, is generated in the direction perpendicular to the current and magnetic field. The voltage is proportional to the current flowing through. Therefore, the current data can be obtained by measuring the voltage. Advantages of Hall Effect Current Transducers High Precision and Stability Hall effect current transducers are known for their high precision, with a basic accuracy of up to 1.0%. And some Hall effect current...

Current sensors mainly use the principles of electromagnetic induction and the Hall effect to detect and measure the current flowing through a conductor and convert it into a corresponding proportional output signal (such as voltage, current, or digital signal). The following are common types of current sensors: Resistor Shunt The resistor shunt connects a precision low-resistance shunt resistor in series with the current path. When current passes through, according to Ohm's law, V = IR. The voltage is proportional to the current. By measuring the voltage value, the magnitude of the current can be known. The advantages of the resistor shunt include high accuracy, fast response speed, low cost, and ease of use. However, its disadvantage is that the device itself does not have an electrical isolation function and is not suitable for measuring large currents and high-frequency alternating currents. Current Transformer A current transformer is a device that works on the principle of e...

Class D audio amplifier mainly uses pulse width modulation (PWM) technology to achieve high-efficiency audio signal amplification through switching devices. Features of Class D Audio Amplifier High efficiency Because class D audio amplifiers work in switching mode, they can efficiently control the output without consuming a lot of power in the amplifier circuit. The working efficiency can usually reach 90% or more. Compact size Due to their high efficiency, class D audio amplifiers almost completely avoid wasting electricity in the form of heat, thereby reducing the need for components such as heat sinks. Secondly, most audio amplifiers utilize compact filters and integrated designs to minimize the overall size of class D audio amplifiers. Good sound effect The switching frequency of class D amplifiers is usually between tens of kHz and hundreds of kHz, which is much higher than the frequency range audible to the human ear. Therefore, the noise level of class D amplifiers is low and t...

The airflow sensor is a device that collects and measures the air flow rate in a pipeline or system in real time. Its function is to provide accurate and reliable flow information, supporting industrial production, medical equipment, and environmental protection facilities, thereby ensuring the stability and safety of airflow in various scenarios, including chemical and medical applications. The following content will introduce the importance of airflow sensors according to different application scenarios. Manufacturing In the production and manufacturing process of many products, it is necessary to accurately monitor the airflow (such as nitrogen, ammonia, inert gas, etc.) in real-time to achieve the safety of industrial automated production, improve production efficiency, and reduce losses.
