Stable measurements through long periods of operation.
new Light FS73 Multipoint Temperature Sensors for different applications
Detect and measure temperature gradients and hot spots easily with multipoint measurements.
Whether looking to monitor temperature gradients or require high voltage compatibility, our temperature sensors are designed to deliver exceptional performance in industrial settings.
Long Term Stability
FBG sensor's response is inherently stable over time, ensuring absolute measurements with no drift.

Passive and dielectric
Optical sensors operate with no active powering or current and can be fully built with dielectric materials.

Suitable for explosive and High Voltage environments
Multipoint measurements
Easy thermal gradient and hot spot detection with several measuring points connected to a single connector of the interrogator.

Cost effective solution for hundreds of sensors per optical interrogator
