Highest Quality and Cost-effective

FiTemp TPK1

The TPK1 sensor is based on an optical quartz silica fiber with fiber Bragg gratings (FBG) housed within a PEEK tubing. It is optimized for use in conjunction with a NEO FBG Interrogator. A single thin sensing cable can encompass up to 30 individual temperature sensing points, offering sensitivity and accuracy. Due to its inherently passive nature, it is particularly well-suited for use in electrical, high-voltage and explosive environments. The flexible sensor can be easily inserted into intricate channels with small bending radii or mounted along curved surfaces.

Pinpoint Precision

Advanced fiber Bragg grating sensors

Our FBG sensors at 850nm are extremely small, measuring only 1-2mm in length.
This short length facilitates more precise sensor positioning, enabling
high spatial resolution of strain and temperature profiles.
Due to their small cores, light can be guided without losses
even in small critical bending radii down to 5mm.

Uninterrupted Precision

Electromagnetic Immunity

Unlike traditional sensors, which can be affected by magnetic fields, our fiber optic technology ensures consistent and accurate measurements without disruption. This makes them ideal for applications in industries such as aerospace and energy where magnetic interference is a concern. With the reliability and precision of our fiber optic sensors, you can count on stable performance in even the most demanding environments.
