Welcome to the OFSCN Official Technical Inquiry & Product Q&A section. As a pre-sales engineer, I am here to provide technical insights regarding our sensing solutions.

The OFSCN® Fiber Bragg Grating Liquid Level Sensor is a specialized application of our high-temperature FBG sensing technology. It is designed to detect liquid levels by identifying the temperature gradient or thermal response difference between the liquid and gas phases.

Technical Overview

The structure of this sensor is based on the OFSCN® 300°C Fiber Bragg Grating Temperature Sensor. Here are the key technical characteristics:

  • Sensing Principle: It utilizes the temperature difference between the liquid (such as liquid nitrogen, liquid oxygen, or hot water) and the surrounding air/gas. By placing multiple FBG points along the sensor, the liquid level is determined by the specific point where the temperature shift occurs.
  • Encapsulation: It features a seamless stainless steel tube encapsulation (standard 0.9mm diameter, customizable down to 0.5mm), providing excellent mechanical protection and chemical resistance.
  • Temperature Range: Capable of operating in extreme environments ranging from -200°C to +300°C, making it suitable for cryogenic liquids (Liquid Nitrogen/Oxygen) as well as industrial hot water.
  • Spatial Resolution: The spacing between measurement points (L2) is fully customizable based on your required liquid level detection accuracy.

Application Considerations

To provide a more precise technical recommendation for your project, could you please clarify the following:

  1. Medium Type: What specific liquid are you measuring (e.g., Liquid Nitrogen, industrial chemicals, or water)?
  2. Detection Range: What is the total height of the liquid level you need to monitor?
