The Null Zone
Magnetic Sensor

So simple, it's genius. The NZMS ferrous debris sensor is a breakthrough that feels obvious—once you see it. Proof that revolutionary ideas are still out there, waiting to be discovered.

Meeting Industry Needs for Reliable Debris Detection

Ferrous debris plagues mechanical lubrication and fuel systems. Traditionally, it has been difficult to detect and was only monitored in critical, high-reliability applications. There has long been a need for a cost-effective, rugged, ultra-reliable, and highly sensitive ferrous debris sensor.

To meet this demand, KasperAero has invented a new sensor category: the Null Zone Magnetic Sensor (NZMS). This patent-pending design enables the creation of an exceptionally elegant and sensitive debris sensor. At its highest sensitivity, NZMS technology redefines the role of debris sensors across a wide range of applications.

Designed for Precision. Built for Scale.

Engineered for Mass Market Production

Sensors starting at just $25—final cost varies with configuration and quantity.

Indiscriminate Operation

Whether the collected debris is a single large chip or an accumulation of ferrous dust, operation is reliable and repeatable.

Ultra High Sensitivity

At the most sensitive, KasperAero NZMS Debris Detectors are capable of sensing 0.015 grams of 10-micron ferrous debris.

Adaptable By Design

For higher capture efficiencies, magnet strength can be increased to suit the application requirements with no effect on sensor operation.

The Language of Detection

The industry hasn't settled on a terminology. The following are all synonyms:

Magnetic Chip Detector (MCD)
Electronic Chip Detector (ECD)
Ferrous Debris Sensor
Wear Debris Sensor
Contamination Sensor
Particle Sensor
Foreign Object Detector
Condition Monitoring Sensor

While these names vary, they all point to the same class of devices. But here’s what no one has ever called them:
Metal Dust Detectors (MDD).

Because until now, no sensor has been capable of detecting micron-sized ferrous dust. Now, with our breakthrough Metal Dust Detector (MDD), you can catch the earliest signs of wear—before even the smallest particles do damage.
