JW1151 / 3351DR micro differential pressure transmitter

JW1151 / 3351DR micro differential pressure transmitter for measuring the pressure inside the furnace and other small differential pressure, and then into 4 ~ 20mA DC output. Intelligent differential pressure transmitter also can communicate with the HART each other through it to set, monitor or with the host machine composed of on-site monitoring system. JW1151 / 3351DR site adjustment smart differential pressure transmitter according to site requirements is the company developed new products, from handheld devices to achieve zero field, configuration and other operations by pressing keys. 1.
