High Static Pressure Limit Controller
P-3610 High Static Pressure Limit Controller
• High sensitivity
• Fast response time
• Complies with ASHRAE recommendations
• Minimizes the possibility of ductwork damage
The P-3610 High Static Pressure Limit Controller is a low volume pneumatic controller designed to return a normally closed fan modulation device to its closed position when the inlet static pressure to the P-3610 rises above its set point. The P-3610 is designed to minimize the possibility of ductwork damage in the event of mechanical or control system failure by limiting the duct high static pressure buildup on the discharge side of the fan or the duct negative static pressure buildup on the suction side of the fan.
The P-3610 functions as a one-pipe bleed control device; its normally closed control port opens when a duct high positive static pressure is sensed, bleeding down the flow controller output line to the controlled device. A damper actuator, for example, receives this signal and closes the damper, thus reducing the duct static pressure. By reversing the barbed fitting on the high port with the venting plug on the low port, the P-3610 can be used as a high negative static pressure limit.
