New high-precision adjustable current sensor
New high-precision adjustable current sensor
With the accelerating process of social modernization, the requirements for mechanical automation are getting higher and higher, and the requirements for high-precision and high-intelligence instruments are getting higher and higher. In terms of angle measurement and control, scientists have been continuously researching and exploring. Traditional angle measurement sensors generally use resistance as the core electrical signal output part, and then perform simple processing to obtain the angle signal. However, this type of resistance angle sensor has a short working life for a long time due to the friction of the contact reed, and its anti-vibration and dust-proof performance is not good. After a long time, the resistance of the reed is damaged due to friction and the accuracy will drop sharply.
Scientists have been working to find a brand-new alternative product, and there have been angle sensors such as resolvers, but the accuracy and environmental adaptability are relatively poor. With the study of the magnetic field, the Hall effect and the giant magnetoresistance effect have been discovered one after another, which has greatly promoted the development of angle sensors. The latest angle sensor now uses the principle of magnetic sensitivity, uses an integrated chip for non-contact sensing of changes in the internal magnetic circuit, and then directly outputs a voltage signal corresponding to the angle after processing with an integrated circuit. The sensor has a programmable integrated processor inside, and a full bridge circuit is used to compensate for temperature changes. The environmental adaptability and stability are greatly improved compared with the traditional angle sensor, because the inside is the principle of non-contact magnetic sensitivity, so the life span is greatly improved.
Although the general magnetic angle sensor is sufficient for most industrial applications, but for some industries, such as aerospace, military industry, precision instruments, detection and alarm, etc., the accuracy requirements are higher, and the general accuracy cannot meet their requirements. okplazas.com, on the basis of the magnetic angle sensor, processed the signal of the sensor, and used a programmable microprocessor to perform finer processing in terms of accuracy and temperature drift, making the sensor temperature lower and stable better.
okplazas.com is now launching this sensor suitable for high-precision and high-intelligence industries, with imported quality and low price. The range and rotation direction can be customized, and the analog signal output and digital signal are optional. Please see the product description page for details.
