Analog Output Signal

Analog - When a metal particle passes the active magnetic field inside the ring an analog voltage value of 1 - 9 V is generated, depending on the size, structure and properties of the metal particle. Metal detectors with an analog output are not recommended for the detection of small pieces of metal. They are predominantly used to inspect broken wires or to guide wires. The output signal is usually transferred onto a switching amplifier.

Dynamic Output Signal

When a moving metal particle passes through the active magnetic field of the ring the amplifier gives a very short output signal for at a couple of milliseconds. Detection of the metal depends on its size, structure, properties and orientation in the magnetic field. Minimum and maximum levels of sensitivity are set using the potentiometer. Since the dynamic ring is only available in NPN versions, its output signal will decrease once metal is detected. Ring detectors with dynamic switching performance have extremely high sensitivity and are used in metal separators for plastics.

Static Output Signal

In a static ring detector, no movement of the metal is required. These detectors are used to ascertain quantities or to control the ejection of larger metal parts. Once a metal particle passes through the magnetic field inside the ring, the amplifier generates a constant output signal for the duration of metal detection. Detection of the metal depends on its size, structure, properties and orientation in the magnetic field. The static ring detector is available in both NPN and PNP versions. In the PNP version the output signal will increase from 0V to +24V once metal is detected. Since static sensors can detect bigger metal parts, they are mainly used to count metal parts or to check if a special metal parts exists or not. This is done without causing any mechanical stress or contacting the product. Ring detectors with the dynamic output signal are recommended for the detection of small metal paticles.
