Introduction to Digital Sensors

Guangzhou Zhongxin introduces digital sensors:
　 　 　 　
Some digital sensors, whose sensitive components are still analog, only undergo analog-to-digital conversion (A/D conversion) in the subsequent signal processing process to become digital sensors. For example, bridge circuit digital sensors. There are also some digital sensors, whose sensitive components themselves output digital signals.

The digital sensor outputs digital signals, which not only have a level 100 times higher than the analog type and are not easily disturbed, but also are transmitted according to the Bifbus field bus communication protocol. The communication speed is ten times that of ordinary RS485, and it is high-speed and has communication error correction ability, ensuring fast and reliable data. Due to the confidentiality of the agreement, on-site cheating is not possible.

The digital weighing sensor has a microprocessor inside, which can diagnose itself. Each sensor has its own address, and the instrument can monitor the output of each sensor online and perform intelligent processing. This not only greatly improves the reliability of the weighing system, but also easily solves some requirements that are difficult to achieve by simulating sensors, such as large tare weight, small scale, and bias detection. In addition, with its unique high-precision high-speed A/D conversion technology, comprehensive sensor digital compensation technology, and remote high-speed explosion-proof communication capabilities, the performance has exceeded the limits of analog sensors and reached the accuracy of OIML C6.
