Model PG551 was developed in response to applications requiring the simplicity of local pressure indication but the durability of a pressure transducer.  Model PG551 incorporates a rigid mounting stem and an integral electronic bar graph display which can be rotated 285 degrees for increased visibility.  Units are easily modified to "stem up" configurations for mounting below the extruder barrel.  Model PG551 incorporates an adjustable alarm setpoint to shut down equipment or warn operators of critical situations.
