Project Overview
This project applied fluorescence-based fiber optic temperature sensing to selected measurement locations in a very low-temperature experimental setup.
Fiber optic probes were used to measure temperature at defined points, while optical fibers transmitted the sensing signals to external temperature monitoring equipment.
The arrangement provides compact point temperature measurement through an electrically isolated optical sensing path.

- Low-temperature sensing application
- Optical signal transmission
- External temperature acquisition
Low-Temperature Measurement Requirement
Very low-temperature experiments can require temperature measurement at small and defined locations where conventional electrical sensors may introduce wiring, isolation or installation constraints.
The project required direct point temperature measurement with a compact sensing element and an optical signal path.
Fiber optic temperature probes were therefore used to measure selected low-temperature locations while keeping the monitoring electronics outside the sensing area.
Fiber Optic Point Measurement Arrangement
Fluorescence-based fiber optic probes measure temperature at defined sensing points in the low-temperature setup.
Each probe corresponds to an individual measurement location, allowing selected points to be monitored independently.
Optical fibers transfer the sensing signals between the probe locations and the external monitoring instrument without conductive electrical sensor wiring at the measurement points.
- Direct point temperature sensing
- Compact probe structure
- Independent measurement locations
- Non-conductive optical signal path
Probe Selection & Optical Connection
Probe type, fiber length and optical connection arrangement were selected according to the measurement location and low-temperature application requirements.
The optical path connects the sensing point to the external temperature monitoring equipment while allowing the measurement electronics to remain outside the low-temperature area.
Different probe structures and channel configurations can be selected according to the required measurement points and equipment layout.
Temperature Acquisition & Multi-Point Monitoring
Signals from the installed fiber optic probes are collected by the external temperature monitoring instrument.
Individual measurement points can be assigned to separate optical channels so that temperatures at different low-temperature locations can be viewed independently.
For experimental setups requiring additional sensing points, the monitoring configuration can be expanded according to the required number of channels.
Project Result
The completed arrangement provides direct fiber optic point temperature measurement at selected locations in a very low-temperature experimental environment.
Fiber optic probes, optical connections and external monitoring equipment form a complete measurement path from the low-temperature sensing points to the temperature acquisition interface.
This configuration provides a practical reference for cryogenic equipment, low-temperature experiments and other applications requiring compact, electrically isolated point temperature sensing.
