Frequently asked questions
Which model should I choose?
The NV14P for level in silos and vessels. The NV10P as overflow protection in conveyors, screws and elevators. Choose the KM version (IP65) if the switch sits inside the equipment or in damp and dusty conditions. Use the selector.
How does a diaphragm switch work?
The material pushes a rubber diaphragm, which operates a microswitch. No electronics and no calibration.
How do I wire it?
Volt-free signal via microswitch, 125 VAC / 15 A or 24 VDC / 0.5 A, with a PG11 cable gland. Connects directly to your existing control system or contactor.
Can it be used in pressure vessels?
No. Diaphragm switches cannot compensate for positive pressure.
