Operating principle
Excitation light travels through a dielectric optical fiber to a fluorescent sensing tip. The instrument evaluates the temperature-dependent decay lifetime of the returning emission rather than relying on electrical resistance or voltage at the measurement point.
Installation approach
Probe geometry, routing length and fixation method must be selected around dielectric clearance, mechanical protection and the thermal interface. Confirm the installation drawing before winding or panel assembly.
Communication and system integration
The final specification depends on the selected model.
Connect the probe to a compatible INNO fluorescence-lifetime measurement instrument. The monitor supplies excitation, calculates temperature and exposes configured alarm or plant-system outputs.

Technical questions
Frequently Asked Questions
Is the sensing point electrically active?
No. The probe uses an optical signal path and contains no powered electronics at the sensing point.
Can the probe configuration be customized?
Probe geometry and fiber length are available according to project configuration. Request a confirmed drawing and datasheet for the selected model.
