Explore High-Temp Sensor →Permanent circuit breaker temperature monitoring of critical current-carrying joints where overheating leads to switchgear failure.
Explore Busbar Sensor →High-density, low-cost-per-point fiber optic temperature monitoring for data centers, UPS rooms and mission-critical electrical assets.
Explore Monitoring System →Fluoroptic temperature measurement uses the temperature-dependent fluorescence decay of a phosphor crystal at the fiber tip — pure optical, immune to electricity and magnetic fields.
A pulsed LED excites the phosphor at the optical fiber temperature probe tip. No electrical signal travels down the fiber.
Decay time of the emitted fluorescence is strictly temperature-dependent — the foundation of fluoroptic temperature sensor technology.
Our fiber optic temperature transmitter measures decay time and converts it to temperature with ±0.5°C accuracy.
Values are streamed via RS485 Modbus RTU to SCADA/DCS — complete optical fiber temperature sensing system.
Because the signal is purely optical — no copper conductor, no metal housing around the sensing element. This makes our fiber optic thermometer ideal for transformers, MRI scanners, microwave cavities and any high-voltage or high-RF environment where traditional optical temperature sensors with metallic parts cannot be used.
From sensor selection to SCADA integration — engineered by our application team, delivered as a complete fiber optic temperature measurement system.
Direct transformer winding monitoring — the foundation of dynamic loading and predictive maintenance with fluorescent fibre optic transformer winding temperature probes.
View Solution Details →Conventional transformer temperature gauge or PT100 sensors can't survive inside windings. Top-oil gauges only reflect indirect readings — the real hot spot may be 10–15°C higher, accelerating insulation aging.
Armored fluorescence probes embedded between windings during manufacturing or retrofitted via oil valve. Multi-point transformer thermal monitoring integrated with SCADA/DCS via RS485 Modbus RTU.
Permanent, battery-free fiber optic temperature measurement system for switchgear at the highest-risk points — bolted joints and contact surfaces.
View Solution Details →Overheating at busbar joints is the #1 cause of switchgear failures. Wireless sensors suffer from battery life and RF issues; infrared has blind spots and requires inspection windows.
Fully dielectric fluorescence probes installed directly on contact points and busbars for continuous switchgear monitoring with configurable alarm thresholds — safe for live installation.
For environments where traditional sensors fail — strong magnetic fields, RF, microwave heating and medical imaging including MRI fiber optic temperature sensor applications.
View Solution Details →Metallic sensors distort MRI images, heat up in RF fields, and introduce safety risks in microwave chambers. Legacy monitoring often leaves the process blind.
