OVERVIEW / OPERATIONTHE BWB "RPS PILOT" IS A 3 WAY, NORMALLY CLOSED OR NORMALLY OPEN, AUTOMATIC, PRESSURE SENSING DEVICE. BY CHOOSING THE APPROPRIATE INLET, THE SENSOR CAN DETECT PRESSURE ABOVE (PSH) OR BELOW (PSL) ANY DESIRED PRESSURE SETTING. BY SELECTING THE CORRECT PISTON & SPRING COMBINATION (SEE PRESSURE CHART), AND EITHER LOOSENING OR TIGHTENING THE ADJUSTMENT CAP, THE SENSOR MAY BE SET BETWEEN 10 AND 10,000 PSI. IT IS NORMALLY INSTALLED ON A PROCESS VESSEL, PROCESSFLOW LINE, OR IN A CONTROL PANEL. THE SENSOR RECEIVES SENSING PRESSURE (PORT P) FROM THE COMPONENT WHICH IT IS MONITORING AND SUPPLY PRESSURE (PORT A OR B) FROM THE SAFETY SYSTEM WHICH IT WILL SHUT DOWN. FEATURES• DRY FILM LUBRICANT APPLIED TO THREADS TO INCREASE THE LOAD-BEARING CAPABILITIES; THUS REDUCING THE CHANCE OF GALLING
WHILE STILL MAINTAINING AN EXTREMELY LOW COEFFICIENT OF FRICTION. • CONTAINS ORINGS FOR ALL PISTON CONFIGURATIONS• DEADBAND +/- 5% OF SET PRESSURE (DEADBAND MAY BE AFFECTED IN HYDRAULIC APPLICATIONS)• SET POINT REPEATABILITY 1% OF SET PRESSURE• EXOTIC MATERIAL AVAILABLE UPON REQUEST• VITON SEALS STANDARD• OTHER ELASTOMERS AVAILABLE UPON REQUEST• DELRIN ADJUSTMENT CAP STANDARD (TEMPERATURES 185°F AND ABOVE STAINLESS CAPS ARE RECOMMENDED)• 316 STAINLESS STEEL CONSTRUCTION• WEIGHT : 4 LBS.
