MEMS-BASED FIBER OPTIC PRESSURE SENSOR FOR THE HARSHEST ENVIRONMENTS

Use with any of Opsens’ WLPI series of signal conditioners

•  Robust packaging

• High operating temperature   
  (>250°C)

• EMI/RFI immunity; intrinsically safe

• Excellent accuracy (0.1%)

• Small size (6.35 mm with housing,   2.5mm or smaller without housing,)

• Low thermal shift ( <0.01%FS/°C)

Opsens’ OPP-A/B are MEMS-based fiber-optic pressure sensors designed for demanding applications.  The OPP-A model comes with a robust metal housing for applications that require rugged sensor used in corrosive environment or for rough handling usage.  The OPP-B model is a bare fiber optic pressure sensor (no metal housing) for applications requiring minimally invasive in-situ pressure measurement.

Combined with Opsens WLPI signal conditioning technology† and with the inherent advantages of fiber optic, the OPP-A and OPP-B deliver long term accuracy, durability, low drift and high fidelity pressure measurements in the harshest environments such as in presence of EMI, RFI, high voltage, combustive/explosive and high temperature.

The OPP-A pressure sensor is available with different housing and cables options customized according to client specific needs. Also, the OPP-A can be built within a plastic housing whenever being used in presence of microwaves or in high voltage environment.
