Ueda Seisakusho PS-105 Falling Pressure Switch

Description:

The Ueda Seisakusho PS-105 Falling Pressure Switch is used in industrial hydraulic and pneumatic systems to detect pressure decreases and provide automatic switching for equipment protection and process control. Commonly installed in hydraulic power units, industrial pumps, compressors, machine tools, and factory automation equipment requiring a falling pressure setpoint up to 4.5 MPa. Maintenance technicians, automation engineers, and system integrators use this pressure switch for preventive maintenance, low-pressure monitoring, and replacement of OEM pressure control devices. The PS Series is designed with an adjustable pressure setting and durable mechanical construction for continuous industrial operation.

Applications:

The Ueda Seisakusho PS-105 Falling Pressure Switch is commonly used in hydraulic systems, pneumatic control circuits, lubrication systems, industrial compressors, injection molding machines, manufacturing equipment, and automated process lines where a pressure drop must trigger an electrical switching action for alarms, pump control, or safety interlocks.
