3351HP type variable static pressure differential pressure transmitter

打印本文       小   中   大

For measuring liquid, gas or vapor liquid level, flow and pressure in high work pressure environment, and then change to 4 ~ DC 20mA signal output. BL1151/3351HP intelligent can communicate with the HART hand operator, through which it is set, monitoring or with the host computer to form a field monitoring system.
