Price of Fiber Bragg Grating Dynamic Demodulator

The price of a Fiber Bragg Grating (FBG) Dynamic Demodulator typically ranges from several thousand to tens of thousands of USD, depending on specifications, customization, and quantity.

Pricing Overview

FBG dynamic demodulators are highly specialized optoelectronic devices used to convert reflected wavelength signals from FBG sensors into precise data for temperature, strain, pressure, or vibration measurements . The cost of these devices is influenced by several factors:

• Customization and Channel Count: Devices can support multiple channels (up to 32 or more) and high-frequency sampling (up to 100 Hz or higher). More channels and higher sampling rates increase the price .
• Sampling Frequency and Precision: High-precision demodulators with wavelength repeatability of ±1 pm or better are more expensive due to advanced optics and electronics .
• Software and Integration: Advanced software ecosystems for remote management, closed-loop control, and secondary development interfaces can add to the cost .
• Quantity Ordered: Bulk orders reduce unit cost, while single or small-quantity orders are more expensive .
• Delivery and Calibration: Shipping, calibration, and installation services may also affect the final price .

Typical Price Range

• Portable or standard laboratory-grade FBG demodulators: Approximately $5,000 to $15,000 USD per unit, depending on features and channel count .
• High-end, multi-channel, high-frequency dynamic demodulators: Can reach $20,000 to $50,000 USD or more, especially for fully customized industrial or research applications .

Recommendations for Buyers

1. Specify Requirements: Clearly define the number of channels, sampling frequency, wavelength range (e.g., C-band 1525–1565 nm), and intended application.
2. Request Quotes: Contact manufacturers like DCYS, OFSCN, or BWS-Tech with detailed specifications to obtain accurate pricing .
3. Consider Bulk Orders: If multiple units are needed, inquire about discounts for bulk production.
4. Check Warranty and Support: Ensure calibration, installation guidance, and warranty terms are included, as these can affect overall cost . In summary, FBG dynamic demodulator prices vary widely based on technical specifications, customization, and order size, with typical costs ranging from $5,000 to over $50,000 USD per unit. Buyers should provide detailed requirements to manufacturers to receive precise quotations.
