Mechanical pressure switch NT11 series

Product Overview
The NT11 series mechanical pressure switch is connected to a precision spring with a built-in piston. When the pressure changes, the amount of spring expansion and contraction changes accordingly. When the pressure reaches the set value, the preset mechanical structure will be triggered and a switch signal will be issued. Piston type pressure switch, which consists of piston sealing ring, piston cylinder, etc., can withstand system pressure of 30MPa.
Shell material: galvanized steel and (304) stainless steel.
Pressure sensitive component raw material: Rubber is imported and made from Germany.
For special user needs, protective covers and sealed connectors need to be added as a complete set before leaving the factory. For example, pressure switches on construction excavators need to be equipped with protective covers and sealed connectors. The pressure switches produced by our factory have successfully replaced imports and are widely used in ships, railways, and engineering machinery.

Applicable Medium

Working medium: water, oil, and compressed air.

Product Features

The compact pressure switch is designed for OEM applications and is an ideal choice for remote control systems for engineering machinery, marine valves, and other equipment that require high pressure resistance. The ultra long volume pressure ratio can be set by the factory or currently available
Field regulation.
