DIAS Non Contact IR Pyrometer DT4L

The Digital Pyrometers PYROSPOT DT4L are specifically designed for industrial purpose. The devices are suitable for temperature measurement from –40 °C to 1000 °C on many different nonmetallic or coated metallic surfaces. The solid body allows usage even under rough environmental conditions.

Applications: Large sheets of glass or metal exiting an oven, fabric and paper, or continuous piles of material along a conveyor belt. 


Tax /GST included

The temperature linear standard output signal of 0/4 to 20 mA allows easy implementation in existing measuring and controlling systems. The device is equipped with a galvanically isolated RS-485 interface, which allows parameterising and software evaluation even in bus systems. All parameters are adjustable via push-buttons and display directly on the device. Also by using the comfortable parameterising and evaluation software PYROSOFT Spot the parameters can be easily adjusted to the application.

Typical application areas:
• Paper and packaging industry
• Kiln engineering
• Glass and ceramics industry
• Food industry
• Chemical industry
