INNO fibre optic temperature sensors ,temperature monitoring systems.
- Fiber Optic Temperature Sensors (FOTS) offer unparalleled performance in extreme environments where traditional sensors fail, primarily due to their complete immunity to electromagnetic interference (EMI), radio-frequency (RF), and high voltages.
- Their applications span critical industries from Energy and Semiconductor manufacturing to advanced Life Sciences, providing precise, real-time data for safety, process control, and quality assurance.
- The intrinsic safety, small size, and high accuracy of FOTS make them the superior choice for monitoring critical assets like transformers and switchgear, as well as for enabling sensitive medical procedures like MRI and RF ablation.

Data Centers & Energy Sector
In the Energy sector, reliability is paramount. From power generation to distribution, monitoring the thermal health of critical assets prevents catastrophic failures and costly downtime.
- Advantages: Fiber optic sensors provide real-time temperature data for bus ducts, cable trays, and battery storage systems in Data Centers without being affected by the high electrical noise. This proactive monitoring prevents thermal runaway and improves energy efficiency.
- Application: Continuous monitoring of critical connection points and power systems ensures operational continuity and protects high-value IT infrastructure from thermal damage.
Oil-Immersed & Dry-Type Transformers
The lifespan of a transformer is dictated by the temperature of its winding insulation. Direct, accurate measurement is the only way to safely optimize load and extend asset life.
- Advantages: FOTS are the only technology that can be safely embedded directly into the transformer windings during manufacturing. Their dielectric properties make them immune to the extreme high voltages and magnetic fields inside both oil-immersed and dry-type transformers, providing precise hotspot temperature data that simulated models cannot match.
- Application: Real-time hotspot monitoring enables dynamic load management, prevents premature aging of insulation, and provides critical data for condition-based maintenance, averting catastrophic failures.
Switchgear, Motors & Generators
Failures in medium and high-voltage switchgear, motors, and generators are often preceded by overheating at critical connection points. Early detection is key to preventing fires and outages.
- Advantages: Being immune to EMI and high voltage, fiber optic sensors can be placed directly on switchgear busbars, circuit breaker contacts, and inside the stator windings of large motors and generators. This provides a safe, direct measurement of temperature where arcing and faults are most likely to originate.
- Application: Continuous online monitoring of these critical points provides early warnings of loose connections or insulation breakdown, allowing for scheduled maintenance before a major failure occurs and enhancing personnel safety.
Industrial Process Control
In many industrial settings, precise temperature control in the presence of aggressive chemicals or intense electromagnetic fields is crucial for product quality and process efficiency.
- Advantages: The glass fiber construction is chemically inert and immune to the harsh conditions found in chemical reactors and industrial ovens. This ensures stable and reliable process control where traditional sensors would corrode or provide inaccurate readings due to interference.
- Application: Monitoring temperatures in chemical synthesis, food processing, and materials curing to ensure consistent product quality, optimize reaction rates, and improve safety.
Semiconductor Manufacturing
Semiconductor fabrication demands sub-degree temperature precision within extreme RF and plasma environments. FOTS are a critical enabling technology for advanced process control and yield optimization.
Plasma & Chemical Vapor Deposition (CVD)
- Application: Sensors are embedded in electrostatic chucks (ESCs) to provide real-time wafer temperature profiles during plasma etch and CVD. Their immunity to the intense RF fields ensures the stable process control necessary for uniform thin-film deposition and etching, directly impacting device performance and yield.
Induction & Microwave Heating
- Application: In processes like rapid thermal annealing (RTA) using induction heating or microwave plasma, FOTS provide the only means of accurate, direct temperature measurement. They are unaffected by the high-power electromagnetic fields that would instantly destroy or incapacitate electronic sensors.
Comparison: Fiber Optic vs. Traditional Sensors
| Feature | Fiber Optic Sensors (FOTS) | Thermocouples / RTDs |
|---|---|---|
| EMI/RF/Microwave Immunity | Complete Immunity. Inherently non-conductive and transparent to electromagnetic fields. | Highly Susceptible. Prone to noise, induced currents, self-heating, and catastrophic failure. |
| Electrical Safety | Intrinsically Safe. Dielectric material eliminates all risk of electric shock and arcing. | Potential risk of conducting high voltages to monitoring equipment and personnel. |
| Accuracy & Precision | High accuracy (typically ±0.2°C or better) and stable with no calibration drift. | Accuracy can be compromised by interference, lead wire resistance, and sensor drift over time. |
| Size & Invasiveness | Extremely small and flexible, allowing for minimally invasive placement in tight spaces. | Generally larger and more rigid, which can perturb the measurement environment. |
| Ideal Environments | High voltage, MRI, RF heating, microwave, plasma, explosive atmospheres. | Electromagnetically clean, stable, and non-hazardous environments. |
Life Sciences & Medical Applications
In the Life Sciences, accurate temperature monitoring is essential for patient safety, therapeutic efficacy, and research integrity, especially in the presence of advanced medical imaging and treatment technologies.
Magnetic Resonance Imaging (MRI)
- Application: FOTS are the only sensor type that is 100% MRI-safe. They are used for monitoring patient core body temperature, testing for RF-induced heating in medical implants (SAR monitoring), and for temperature control in fMRI research without causing image artifacts.
RF / Laser Ablation
- Application: During therapeutic RF and laser ablation for tumor removal, the small, fast-responding sensors are inserted into or near the target tissue. They provide critical real-time feedback to control the energy delivery, ensuring complete ablation of the target tissue while protecting surrounding healthy organs.
High-Intensity Focused Ultrasound (HIFU)
- Application: For non-invasive HIFU treatments, fiber optic sensors are used in phantom tissues to validate and calibrate the system. They accurately map the thermal profile at the focal point, ensuring the delivery of a safe and effective therapeutic dose.
