★ Overview
The FB3351T intelligent pressure transmitter is a high-performance and highly reliable standard pressure transmitter that uses a silicon material sensor combined with a single-chip microcomputer. At the same time, the FB3351T pressure transmitter is based on the fieldbus HART protocol technology, which superimposes high-frequency signals on a 4-20mA DC output for remote communication, making it convenient for users to configure and set up on site.
The FB3351T pressure transmitter adopts a threaded direct installation method, which is easy to install and use. It is suitable for various occasions and media in industrial measurement and is an ideal pressure measuring instrument in the field of industrial automation.
