ODP-B Fiber optic displacement sensor

Multi-purpose fiber optic displacement sensor

Opsens Solutions’ ODP-B fiber optic displacement sensor is designed to offer high precision in the most demanding environments. Combined with Opsens Solutions’  WLPI signal conditioning technology (# 7,259,862) and with the inherent advantages of fiber optics, the ODP-B delivers unprecedented repeatability, resolution and  reliability in the most adverse conditions such as high level of EM, RF, MR and microwave field environments.

The standard model comes with 10 mm or 25 mm linear stroke length and with one micron resolution. The new generation of displacement sensor (ODP-B sensor) is fully made of stainless-steel material and dielectric material to remove any corrosion and galvanic corrosion risk. Specialy design for ruggedized industrial application.

The ODP-B is compatible with all Opsens Solutions’ WLPI signal conditioners. This precise and robust sensor, available with different optical cables length is customizable according to customer specific applications or for OEM-type applications.
