Hall effect position sensors are noncontact devices that function via an electrical potential (for example, a voltage) that is developed across an axis perpendicular to an applied current flow and the presence of a magnetic field

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance

Eddy current instruments are nondestructive testing (NDT) devices that induce detectable eddy currents in conductive materials.

Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.

Thickness gages are used to make precise dimensional measurements on a wide variety of coatings and materials including steel, plastic, glass, rubber, ceramics, paint, electroplated layers, enamels, etc

Electrical current sensors measure AC and/or DC current levels.

Flaw detectors are nondestructive testing instruments that can detect or measure defects in raw materials or finished products.
