FLUORESCENCE-BASED POINT TEMPERATURE SENSING

Standard Fluorescent Fiber Optic Temperature Probe

Designed for direct point temperature measurement in high-voltage, EMI, RF, microwave and other electrically sensitive environments. Probe structure and fiber length can be configured for different measurement locations.

  • Fluorescent fiber optic temperature sensing
  • Electrical isolation for high-voltage measurement
  • EMI / RFI immune temperature measurement
  • Configurable probe diameter and fiber length
  • Compatible fiber optic monitoring instruments

Product Overview

The Standard Fluorescent Fiber Optic Temperature Probe is designed for direct point temperature measurement where electrical isolation, EMI immunity or compact probe placement is required.

A fluorescent sensing material at the probe tip responds to excitation light transmitted through the optical fiber. The return optical signal is processed by a compatible temperature transmitter or monitoring instrument to provide temperature data.

Probe dimensions, fiber length, protection and connection options can be selected according to the measurement location and operating environment.

Key Benefits

Point Temperature MeasurementMeasures temperature directly at the selected sensing location.
Electrical IsolationNon-conductive optical sensing path at the measurement point.
EMI / RFI ImmunityOptical signal transmission is unaffected by electromagnetic interference.
Small Probe StructureSuitable for compact or restricted measurement locations.
Configurable Fiber LengthFiber length can be selected according to the installation distance.
Multi-Channel CompatibilityCan be used with compatible single-channel or multi-channel monitoring instruments.

Probe Design & Working Principle

Probe Construction

Fluorescent Sensing Tip

Provides point temperature measurement.

Optical Fiber

Carries excitation and return optical signals.

Protective Sheath / Coating

Selected according to the installation environment.

Connector

Matches the selected temperature transmitter or monitoring instrument.

Optional Extension Cable

Extends the optical connection where additional routing length is required.

How It Works

Excitation Light

The transmitter sends excitation light through the optical fiber.

Fluorescent Probe Tip

The sensing material at the probe tip responds to the excitation light.

Return Optical Signal

The fluorescence return signal travels back through the optical fiber.

Temperature Data

The transmitter processes the optical signal and converts it into a temperature value.

Excitation Light Fluorescent Probe Tip Return Optical Signal Temperature Data

Temperature is determined at the location of the fluorescent sensing tip, providing direct point measurement without an electrical sensing element at the measurement point.
