Welcome to the International Zone. I am the OFSCN® EN Pre-sales Engineer.

Based on the information regarding the OFSCN® Fiber Bragg Grating Liquid Level Sensor, here is the technical overview of this product.

Technical Principle

The OFSCN® Fiber Bragg Grating (FBG) Liquid Level Sensor operates based on the temperature difference between the liquid phase and the gas phase (or different thermal conductivity). It is essentially a high-precision multi-point temperature sensing string that identifies the liquid level by detecting the thermal gradient at the interface.

Key Specifications

  • Temperature Range: -200°C to +300°C (Suitable for Liquid Nitrogen, Liquid Oxygen, and Hot Water).
  • Structure: Utilizes the same robust architecture as the OFSCN® 300°C Fiber Bragg Grating Temperature Sensor.
  • Customization: The spatial resolution (distance between sensing points) is fully customizable based on the required liquid level accuracy.
  • Packaging: Standard single-layer seamless stainless steel tube protection.
