打印本文       小   中   大

3351GP type pressure transmitter for measuring liquid, gas or steam liquid level, density and pressure, and then change into 4 ~ 20mADC signal output. 3351GP intelligent pressure transmitter can communicate with the HART hand operator, through which it is set, monitoring or with the host computer to form a field monitoring system. 3351GP field adjustment type intelligent pressure transmitter is the company according to the requirements of the field of development and development of new products, can be separated from the hands of the operator, through the button to achieve the scene zero adjustment, configuration and other operations.
