Capacitive remote differential pressure / pressure transmitter

Capacitive remote differential pressure / pressure transmitter intelligent pressure (including negative pressure) transmitter can communicate with each other and the HART through it to set, monitor or with the host machine composed of on-site monitoring system. Intelligent field adjustment pressure (including negative pressure) transmitter is the company according to site requirements developed new products, from handheld devices to achieve zero field, configuration and other operations by pressing keys.
