Wie funktionieren Laser-Distanzsensoren?

Laser-Distanzsensoren messen Abstände mithilfe eines Laserstrahls, der von einer Oberfläche reflektiert wird. Aus der Laufzeit oder Phasenverschiebung des Lichts berechnet der Sensor den exakten Abstand.
Proxitron Laser-Distanzsensoren ermöglichen präzise Messungen auch bei hohen Temperaturen oder großen Entfernungen und werden u. a. zur Positionskontrolle, Dickenmessung und Regelung von Materialflüssen eingesetzt.

What is a pyrometer and when is it used?

A pyrometer measures surface temperature without contact by detecting the emitted thermal radiation. In industrial processes – particularly in metal, glass, and steel production – this technology is crucial for quality assurance.
Proxitron pyrometers are designed for measurement ranges up to 1 800 °C and withstand the same harsh conditions as our infrared and light barrier systems.

What are optical sensors and where are they used in industry?

Optical sensors detect objects, movement, or position using light – usually in the visible or infrared range. In industrial applications, they are used for product tracking, position detection, and quality control.
Proxitron optical sensors are specially designed for high ambient temperatures up to 600 °C and operate reliably in rolling mills, production and assembly lines, as well as in automation systems.

What is an HMD sensor (Hot Metal Detector)?

An HMD sensor detects hot metal contact-free by measuring its infrared radiation. In steel and rolling mills, HMD sensors are used to monitor the position, presence, and movement of glowing material.
Proxitron HMD sensors are designed for extreme environments and ensure precise detection at temperatures above 1 000 °C, making them essential for safe and efficient process control.
