The ZN210/220 flange mounted differential pressure transmitter adopts single crystal silicon resonant sensor technology, which minimizes the effects of overvoltage, temperature changes, and static pressure, providing unparalleled long-term stability. Fieldbus is a bidirectional digital communication system, an innovative technology for configuring instrument control systems, and also a promising replacement product for the widely used standard 4-20mA analog communication in field instruments.
The JT series offers two fieldbus modes, FOUNDATION fieldbus low voltage mode and PROFIBUS PA equipment, to achieve collaborative work between Yokogawa Electric and other suppliers. In terms of software, the JT series uses two AI function blocks to calculate differential pressure and static pressure, thereby achieving flexible instrument configuration.
