FA sensors

No longer available.
Replaced by the Endurance Fiber series.
The replacement is from the same manufacturer and therefore functionally and mechanically (almost) identical.

Brochure Endurance Fiber

The Endurance Fiber Optic Series offers high-temperature fiber-optic pyrometers to provide a robust solution for manufacturers looking to improve product quality and uniformity, reduce scrap rates, maximize throughput and minimize energy costs. The fibre-optic sensor allows this series to be used in hard-to-reach areas and high ambient temperatures to view critical process operations, as well as innovative tools to better understand production data. Multiple lens, focus options are available for different mounting distances. The built-in laser option can be used to check process alignment for local observation when the sensor is located in a hard-to-reach area.

Endurance Fiber Optic IR sensors have a rugged stainless steel housing designed to meet IP65 environments and the sensor can optionally withstand high ambient temperatures: up to 315°C without cooling.

With the Endurance software included, you can archive your process temperatures for data analysis and set up the sensor.

The Endurance Series is backed by the best-in-class 4-year warranty.

There will certainly be a suitable replacement or additional Fiber sensor for the Marathon FA from the Endurance Fiber sensors! Of course we are happy to assist you in making your choice. Please do not hesitate to contact us!
