How Much Do You Know About The Working Principle And Characteristics Of Hot Metal Detectors?

How much do you know about the working principle and characteristics of hot metal detectors? As the name implies, a hot metal detector is a test instrument for identifying the leading edge and direction of hot metal motion. As a manufacturer specializing in the production of hot metal detectors, in the following content, we will help you better understand this equipment by introducing a series of factors such as their working principle and product characteristics.

The working principle of the hot metal detector: the hot metal detector receives the near-infrared light emitted by the high-temperature object, and directly focuses on the photosensitive device through the optical part, and the photosensitive device converts the optical signal into an electrical signal, which is processed by the controller and output. A switching signal is given to the control structure for automatic control purposes.

Hot metal detector product features: can work in harsh environments (such as high temperature, humidity, water mist, dust and other harsh environments). It can work continuously and reliably for a long time. The detector is a power supply, controller and output integrated type, which is easy to install.

We know that the scanning hot metal detector is an instrument with high sensitivity, short response time, wide vertical field of view, narrow lateral field of view and accurate positioning. It uses a lead sulfide detector. The spectral response produced by different photodetectors shows that the lead sulfide photodetector has a strong ability to detect hot metals. Here are three of its characteristics:

Feature 1, the scanning hot metal detector can work in harsh environments, whether in high temperature, humidity, water mist, dust and other harsh environments. Feature 2, can work continuously and reliably for a long time. Feature 3, the detector is a power supply, a controller, and an output integrated type, and is convenient to install.
