...The CDL series pressure switches are characterized by their reliability over long periods and under adverse conditions. After extended periods of inactivity, they ensure safe operation only when the capacitor begins to outgas at the end of its life.

...The level switch NIS contains 1 to 4 membrane pressure switches and the same number of connected immersion tubes. As the liquid level rises, the air in the immersion tubes is compressed. With a pressure increase of up to 10 mbar (level difference of 100 mm H2O), a snap switch is activated via the membrane. If the level drops by up to 50 mm, the air in the immersion tube relaxes, and the switch resets. The NIS does not require its own operating voltage. Available in PVC-U and PP housings with EPDM or FKM seals. An ideal solution for overflow protection in tanks and collection pits.

...Mechanical Membrane Level Switch The mechanical switch MBA100 reliably measures the level in free-flowing bulk materials such as granules, powders, or feed. A switching process is triggered by light pressure from the bulk material on the stainless steel membrane – only 950 grams are sufficient for this. A microswitch is activated, which switches an electrical signal. The device itself does not require any power for its operation.
As a globally operating family business with over 10,200 highly qualified employees, the WIKA Group is a world leader in pressure and temperature measurement technology.
