Electromagnetic CPC Sensor Model:EMW
Overview
New Concept— Detection by Electromagnetic Wave.
The furnace can operate safely because there is no need for sensors or other structures inside it.
Electromagnetic CPC sensors are new kind of sensor. They emit electromagnetic waves from antennae embedded in the furnace wall and use the transmission time taken for the waves reflected from the strip edges to return to the antennae to measure the strip position.
Feature
- The system operates safely because there is no interference with the strip and equipment inside the furnace.
- No maintenance is required.
- Dirt (dust and fumes) in the atmosphere inside the furnace has no effect. There are no consumable parts.
- The sensors are compact and light, for easy installation in a small space.
- Construction costs are low.
Detection operating principles and equipment configuration
Electromagnetic waves from the antennae are reflected from the strip edges and the transmission time taken for the waves to return is used to measure the strip position. Even if dirt or other contaminants reduce the reception sensitivity, the transmission speed of the waves does not change, so the measurement is unaffected.
