The INNOFZ 3-channel fiber optic temperature transmitter is engineered specifically for three-phase power transformer winding temperature monitoring. Using fluorescent point-type optical sensing, the system delivers electrically isolated, interference-free temperature measurement directly at the winding hot spot — positioning it between single-point modules and large multi-point hubs as the right-sized solution for three-phase applications.
Wichtigste Merkmale
- Fluorescent point-type optical sensing — zero metal in the sensing path, fully immune to electromagnetic and high-voltage field interference
- Purpose-built 3-channel layout matched to A/B/C three-phase winding monitoring, avoiding the cost and complexity of larger multi-channel systems
- Direct embedding inside transformer windings for true hot-spot temperature capture
- RS485 output for direct integration into substation SCADA / DCS / transformer condition-monitoring platforms
- Rugged, insulated construction rated for long-term operation in high-voltage transformer environments
Systemkomponenten
- Fiber Optic Temperature Transmitter (Demodulator Unit) — core processing unit that demodulates the fluorescent optical signal into a real-time temperature value
- Fluorescent Temperature Sensing Probe — installed at the winding measurement point; signal varies with local temperature
- Fluorescent Optical Fiber — insulated optical link between probe and transmitter, safe inside energized windings
- Display Module — on-site local readout of all monitored channels
- Monitoring Software — multi-point data logging, trend analysis, alarm thresholds, and remote system integration
Anwendungen
- Three-phase power transformer winding hot-spot temperature monitoring
- Oil-immersed and dry-type transformer condition monitoring
- High-voltage switchgear contact and busbar temperature monitoring
- Motor stator three-phase winding temperature monitoring

Häufig gestellte Fragen
Why choose a 3-channel transmitter instead of a single-channel or large multi-channel system?
Three-phase transformers require monitoring at three winding points (A/B/C). A 3-channel transmitter matches this requirement exactly, avoiding the extra cost of a single-point module installed three times over, or the unnecessary capacity of a large multi-point hub designed for many sensors.
Can this transmitter be reconfigured for more or fewer channels?
Yes. Channel count is one of the customizable parameters — see the Technical Parameters table above, and the Customization & Service section for available configuration options.
How is the temperature actually measured at the winding?
A fluorescent probe is embedded at the winding hot spot. Its optical response changes with temperature, and this signal travels through the insulated fiber back to the transmitter, which converts it into a digital reading without any electrical connection at the measurement point.
What support does INNOFZ provide for non-standard installations?
INNOFZ offers pre-sales consultation on probe placement and winding layout, custom probe and fiber specifications, and after-sales calibration support — detailed in the Customization & Service section above.
