Polyimide Transformer Winding Fiber Optic Temperature Probe

A slim, passive point probe for reviewed transformer winding and internal hot-spot installations.

POLYIMIDE-PROTECTED WINDING PROBE

Protect the Optical Path With Polyimide Construction

This probe uses a polyimide protective construction for selected transformer winding and internal temperature measurement points.

The probe does not provide a temperature output by itself. One compatible fluorescence channel is required for each point, and the complete installation must be coordinated with the transformer insulation and assembly design.

  • Polyimide protective construction
  • -40 °C to +260 °C range
  • 2.5 mm sensing tip
  • Passive, electrically isolated probe

Product Overview

The polyimide-enhanced transformer winding temperature probe is a passive fluorescence probe for a selected internal winding point. Its polyimide protective construction and 2.5 mm sensing-tip diameter support projects where a compact probe geometry is part of the installation review.

A probe provides the measurement point, not the complete monitoring function. Connect it to a compatible fluorescence instrument when the project also requires temperature display, alarming, logging or plant communication.

Where a Slim Winding Probe Fits

A compact sensing tip can be valuable where the winding build and insulation structure leave limited room for a measurement assembly.

  • Direct point measurement at a selected internal location.
  • Passive optical sensing path at the temperature point.
  • Project review required for final probe placement and route.

Coordinating Probe Placement With Transformer Insulation

The probe should be selected as part of the internal construction plan, not after the winding point is inaccessible.

  • Review the target point with the transformer designer.
  • Confirm fiber routing and protection through the build.
  • Select a compatible channel count for all planned points.

Passive Point Sensing With a Compatible Instrument

The fluorescent sensing tip measures one selected point. A compatible instrument supplies the optical excitation, processes the returned signal and provides the temperature output. See the standard fluorescence probe for the full measurement principle.

Slim Polyimide Winding Probe Construction

The compact protective construction is selected around available winding space, insulation coordination and the planned optical route.

Polyimide protective construction

The optical route uses the product’s polyimide protection for the selected internal installation.

Compact sensing tip

The fluorescent tip is positioned at the defined winding or internal temperature point.

Optical lead to host

The fiber route ends at a compatible fluorescence instrument selected for the project.

Frequently Asked Questions

Why use polyimide protection?

It provides a slim protective construction for the optical route in application-specific transformer installations.

Is this a complete transformer monitoring system?

No. It is a passive probe and requires a compatible instrument, optical connections and project-specific installation.

How many locations does one probe measure?

One probe measures at one fluorescent sensing tip.

What range is for this configuration?

The standard configuration supports -40 °C to +260 °C. Final performance must be confirmed for the selected construction.

Can the dimensions be customized?

Probe geometry and routing requirements can be reviewed, but final availability must be confirmed for the project.

What should the transformer manufacturer provide?

Provide winding drawings, target points, insulation environment, route constraints, temperature range and required probe quantity.

Configure a Polyimide Winding Probe

Send the transformer winding drawing, target points, temperature range, internal route and required channel count.
