FST500-203 intelligent pressure controller is a integrated instrument combined with pressure transmitting, live pressure digital display, 

control or alarm.  It's high performance makes itself can take over the old Hall and electrical switches.  Using 4-digital display to show 

live pressure value.  The product can be adjusted on zero point and is featured with strong resistance against overpressure, overflowing, and 

reverse direction protection. 

Applicable Scope
