Adjustable Mechanical pressure switch NT330 series
- Brand：NOIKE-AH
- Model：NT330
Specification
Adjustable Mechanical pressure switch NT330
Product Overview
The Adjustable Mechanical pressure switch NT330 is designed for reliable pressure monitoring and automatic control in industrial systems. Featuring a compact structure, wide pressure measurement range, and high repeatability, it provides dependable switching performance for a variety of pressure control applications.
The switch utilizes a bellows sensing element combined with a precision mechanical mechanism to detect pressure changes and automatically control electrical circuits. Adjustable hysteresis and silver-plated contacts ensure stable operation and long service life in demanding industrial environments.
Operating Principle
The Adjustable Mechanical pressure switch NT330 incorporates a built-in bellows sensing element and a mechanical switching mechanism.
When the system pressure increases or decreases, the bellows expands or contracts accordingly. This movement works together with the adjustable spring mechanism to generate mechanical displacement.
The displacement is transferred through an internal lever mechanism, which actuates the electrical contacts to open or close the control circuit, enabling automatic pressure monitoring and equipment control.
