The OPP-C pressure sensor is compatible with all Opsens Solutions’ WLPI (Patent #7,259,862) signal conditioners. This compact and very robust probe can be customized to specific customer requirements. The fiber optic extension cable can be a maximum length of 3 kilometers.
Opsens Solutions’ OPP-C, MEMS-based fiber-optic pressure sensor, is perfectly tailored to meet the challenges of pressure monitoring Applications in submerged and/or harsh environments.
The OPP-C sensor delivers long term accuracy, durability and high fidelity pressure measurements with a pressure operating range of up to 1,000 PSI.
It’s the prefect piezometer: Completely sealed, with a stainless steel body and diaphragm, the OPP-C is designed to work in adverse conditions of temperature, pressure, and toxic or corrosive atmospheres. It can be grounted in place if needed.
With the inherent advantages of fiber optic, it is not subject to interference from electromagnetic interference, vibrations and lightning that may be present in the sensing environment.
