This topic discusses the **OFSCN® Ceramic-encapsulated Fiber Bragg Grating (FBG) Temperature Sensor**, which is specifically engineered for temperature monitoring in environments requiring electrical insulation.

### Technical Overview

Unlike traditional metal-encapsulated sensors, this product utilizes ceramic tube packaging to ensure insulation under specific voltage conditions, making it ideal for electrified equipment or high-voltage environments where metallic components might pose a risk.

**Key Technical Specifications:**

- **Encapsulation:** Single-layer ceramic tube (can be reinforced with seamless steel tube nesting if needed).
- **Standard Dimensions:** Default outer diameter (OD) is 2.0 mm, with a customizable 3.0 mm OD version available.
- **Temperature Range:** Highly customizable, supporting a maximum range from -270°C up to +800°C.
- **Default Length:** 20 cm (customizable from 10 cm to several decimeters).
- **Fiber Connector:** Default FC/APC; other types like ST, LC, SC (PC or APC) are available upon request.

### Applications

1. **Electrified State Monitoring:** Real-time single or multi-point temperature detection for power electronics, transformers, or busbars.
2. **Temperature Compensation:** Serving as a reference sensor to eliminate temperature-induced errors in strain and stress measurement systems.
