Price of fiber optic grating pressure ring assembly

Fiber optic grating pressure sensors, including pressure ring assemblies, generally cost significantly more than standard FBG temperature sensors, often 50–80% higher, depending on design and packaging.

Fiber Bragg grating (FBG) pressure sensors convert pressure into strain using precision diaphragms or mechanical assemblies, such as pressure rings, and are engineered for high accuracy and durability in industrial environments . The price depends on several factors:

• Sensor type and packaging: Bare fiber sensors are cheaper, while packaged sensors with protective housings or hermetic sealing command higher prices .
• Pressure range: Sensors designed for 0–10 MPa are less expensive than those rated for 0–100 MPa due to increased engineering complexity .
• Material and coating: Stainless steel, gold-coated, or specialized metallization options increase cost .
• Customization and supplier: Custom FBG assemblies, including pressure rings, may require specialized fabrication, affecting price . Typical pricing estimates: While exact figures vary by supplier and configuration, industrial FBG pressure sensors often cost several hundred to over a thousand USD per unit, reflecting the precision engineering and protective packaging required . Bulk orders or multi-sensor arrays can reduce per-unit costs. For procurement, it is recommended to contact verified suppliers directly to obtain quotes tailored to your required pressure range, packaging, and environmental specifications. Suppliers in China, such as those listed on Alibaba or Made-in-China, offer competitive pricing and customization options for FBG pressure sensors .
