Sensor To Detect Plastic Only

Plastic granulate sugar oil aqueous media directly or through a container wall.

Sensor to detect plastic only.

Similar to the question pesticides detection sensor there isn t a specific sensor to look for glasses or plastic polymers. They do not detect non metal targets such as plastic wood paper and ceramic. The rectangular housing plastic for inductive sensor by bernstein is a robust plastic case with a size of 27x10mm and 60x36mm. Unlike photoelectric sensors this allows a inductive proximity sensor to detect a metal object through opaque plastic.

Dr zia s tiny 2 5 mm by 2 5 mm sensor is able to be swirled through a liquid and detect concentration levels as low as two parts per billion using a test that takes less than 10 minutes. Inductive sensors detect metal objects contactless and wear free. Metals are conductive while plastics ceramics are not. You have to do some logic that both type of sensors are on then it is metal only capacitance sensor is on it is plastic or glass.

The question is vague but here is my train of thoughts. Typical applications are in the wood paper glass plastic food chemical and semiconductor browse capacitive linear position sensors datasheets for ifm electronic gmbh. Still you could go for indirect methods like reflectivity infrared signature by black body radiation. In contrast to inductive sensors which only detect metallic objects capacitive sensors can also detect non metallic materials.

Inductive proximity sensors can only detect metal targets. Google for omron or ifm proximity sensors learn and find something you want and purchase. If you want to go more complex than 1. Even though you cou.

Capacitive sensors for level detection use a spherical field to detect the product bulk material or liquid e g. Or you want to distinguish diffeent types of plastic say pvc vs. Balluff s patented hybrid capacitive technology sensor series detects water based conductive media through thick glass and plastic walls while compensating for moisture foam and material build up.
