Used to measure liquid, gas or steam level, density and pressure, and then put it into a 4 ~ 20 mA DC signal output. FY1151/3351 DP intelligent and hand hold is mutual communication HART, through it Settings, monitoring or and upper units into site monitoring system. FY1151/3351 DP field adjustable intelligent difference pressure transmitter is the company according to the requirements developed new products, but from the hand exercise, through the key way realization site for zero, configuration, operation.
