Fiber optic temperature measurement systems

Fiber optic temperature measurement devices

Temperature control is crucial in many industrial processes.

Our fiber optic temperature devices type FOTEMP are designed to perform well in environments with microwave radiation and high-frequency interferences. They are not only suitable for high voltage applications, magnetic fields, and aggressive industrial settings but also provide accurate temperature monitoring to protect your supplies and assets.

Our FOTEMP devices come with customizable probes, sensors, and accessories to meet your specific needs. They can be calibrated from -200°C to +300 °C and seamlessly integrate with our monitoring software for comprehensive data logging and visualization.
