Flexible Exhaust Pipe 47686128001 Flex Hose Bellows Tube for Rotary Screw Air Compressor

Detailed Product Description

Switch Logic vs. Sensor Signal

A pressure switch is a threshold device: when pressure reaches a setpoint, internal contacts open or close to energize/de-energize a circuit. This differs from a transducer that sends a variable signal to a controller. The 47686128001 is commonly mounted on the separator tank, discharge line, or receiver tank, directly influencing when the compressor loads, unloads, or stops. Its mechanical action—diaphragm or piston responding to pressure—makes it robust but subject to wear and contact burnout.

Key Benefits

• Setpoint Control: Switches at adjustable pressure thresholds for precise start/stop and load/unload management.
• Motor Protection: Prevents over-cycling and over-pressure conditions that stress the drive system.
• Direct Action: No controller required for basic on/off pressure control in many systems.
• Adjustable Range: Dial or screw adjustment allows tuning to site air demand.
• Also Called: pressure switch, compressor pressure switch, air pressure switch, pressure cut-out switch, pressure control switch, pressure transducer switch.

Common Applications

• Rotary screw air compressors with pressure-based motor control
• Separator tank, discharge line, and air receiver installations
• Industrial plants, workshops, and compressed air stations
• Compressor electrical maintenance and spare-parts inventory
