CT Series

Affordable robust industrial pyrometers for applications with high surrounding temperatures

Affordable robust pyrometers for industrial applications with high ambient temperatures up to 2000  C

Small Head, Separate Control Box

The pyrometers of the Optris CT series are equipped with one of the world’s smallest infrared sensing head with a high optical resolution of up to 75:1. The separate control box offers a high variability due to selectable analog outputs as well as several digital interfaces. The CT sensors have unique advantages for the installation in applications with high surrounding temperatures, such as within the metal, ceramics or glass industry. The robust and ambitious design allows the sensing heads to be used for temperatures up to 250 °C (482 °F) without additional cooling. This advantage helps to reduce the costs for mechanical installations. The variety of different available spectral ranges makes the CT the ideal sensor for manifold application fields.
