FOP-MA Acoustic Fiber Optic Pressure Sensor

The FOP-MA Acoustic Fiber Optic Pressure Sensor is a miniature, all‑optic device designed for acoustic and microphone applications where minute pressure changes must be detected. It measures pressure from 0 to 2 psi, offers a resolution of 0.0075 psi dependent on the signal conditioner, and maintains an accuracy of ±1 % of full scale relative to atmospheric pressure. Frequency response reaches up to 30 kHz when paired with a Veloce 50 conditioner, and the unit connects via a standard ST connector. The sensor operates reliably between - 20 °C and 150 °C, making it suitable for harsh environments.

The sensor’s construction relies on single‑mode silica fibre, a polymer jacket for corrosion resistance and an ST optical connector, which together provide immunity to EMI and RFI. Such fibre‑optic designs are common in precision pressure transducers because they avoid electrical interference and allow operation in electrically noisy settings. Typical fibre‑optic pressure sensors of this class have a length around 150 mm and are packaged to protect the fibre from mechanical stress. The FOP‑MA follows these industry norms while delivering a compact form factor that eases integration into limited space assemblies.

Typical buyers include acoustic equipment manufacturers, automotive sensor integrators, aerospace test rigs and aerodynamic research facilities that require high‑frequency pressure data. Importers should confirm the required signal conditioner compatibility and verify the sensor’s operating temperature range matches the target environment. Trade terms are not disclosed in the listing; prospective buyers need to request MOQ, lead‑time and shipping conditions directly from Week Technology Ltd.

Week Technology Ltd. is located on the 16th floor of Building 3, Zhongke Mansion in Shenzhen, Guangdong, China. The company is listed as an imported supplier with a harbour trust tier, indicating that it meets basic compliance checks for cross‑border trade. Current platform data show a response rate of 0 % and no recorded response time, so buyers should anticipate a need for proactive follow‑up when initiating contact.

The supplier’s profile does not disclose production capacity, years in operation or specific client references. Week Technology Ltd. markets the FOP‑MA sensor as an all‑optic, EMI‑immune solution, and the listing highlights its suitability for demanding sectors such as aerospace and automotive. Importers should verify any claimed certifications or quality‑system documents before finalising a purchase.
