PW130 Low pressure switch with customizable range

PW130 series low pressure switch are made of thin film (low pressure) or piston (high pressure) measuring elements and can be used for gas or liquid pressure detection. When the pressure reaches a set point, the moving part triggers a spring supported micro switch. Panel mount. Can measure neutral gas, air, lubricating oil, oil and other media.

The mechanical low pressure switch is a purely mechanical deformation that causes the micro switch to act. When the pressure increases, the different sensing pressure components (diaphragms, bellows, pistons) will be deformed, and will move upwards. Through mechanical structures such as railing springs, the uppermost micro-switch will finally be activated to output electrical signals. PW130 series pressure switches can provide different pressure, differential pressure, vacuum and temperature ranges, and can also provide different connection methods, various materials and pressure sensing element types. It is precisely because of this flexible selection method that PW130 series pressure Switches can be widely used in various places, such as chemical, petrochemical, oil refining, oil field, drilling platform, oil pipeline and pharmaceutical and other industrial processes
