Compact Mechanical Adjustable Pressure Switch - PN330

Product introduction

The pressure switch has built-in bellows and mechanical structure. When the system pressure rises or falls, the corresponding regulating spring and bellows generate extension or contraction displacement, and the lever pushes the switch to cut off or connect the control loop.
Compact structure, wide measuring range (0... 30bar), high repeatability, hysteresis adjustable, contact silver plated.
