AI Technical Summary
In existing technologies, high-precision pressure transmitters suffer from low communication efficiency, limited scalability, and insufficient reliability, resulting in long calibration cycles, high energy consumption, and low production efficiency.
The pressure sensor multi-channel communication device based on CANFD works in concert with the main control module and the hardware addressing protocol conversion module. Combined with the high-speed extended frame structure of the CANFD bus, it supports near-parallel communication of multiple sensors. The device's reliability and scalability are ensured through a pluggable modular design and an independent channel automatic addressing and heartbeat mechanism.
It significantly improves calibration data throughput efficiency, enhances the space utilization and equipment capacity of the high and low temperature chamber, strengthens overall reliability and maintainability, and simplifies equipment configuration and management, making it more convenient.
