Where to Buy Optical Force and Pressure Sensors

As part of the HBK pantograph monitoring solution for predictive maintenance of pantographs and overhead powerlines, the FS66HDL Heavy duty force sensor is an optical force sensor fully rated for railway applications. The HBK pantograph monitoring solution is a fully optical measurement solution to be installed on regular operating trains, directly on the pantograph. It is based on load and acceleration optical sensors that are passive and safe for accurate measurements on high-voltage levels. Additionally, make the system hybrid by integrating information from vehicle bus signals and GPS to build a graphical map of the infrastructure and its maintenance plan. By using this system, instead of periodic track interruption for maintenance, the owner can continuously assess the overhead power line condition and, plan for maintenance on demand.

The T620 is a high-accuracy and sensitivity single-mode fiber (SM) based Fiber Bragg Grating (FBG) based packaged pore water pressure sensor for operation to 150 psi.

Available in a wide range of optical specifications. Packaged with two internal FBGs to eliminate influences from the ambient environment, the novel transducer mechanism yields a high sensitivity and absolute accuracy optical sensor. Ready for direct use in many applications. Calibration service available upon request. The T620 sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG sensors.

The TFP10 is an all-fiber micro Fabry–Pérot (uFP) sensor for use in applications to 700 °C. Using laser micro- machining technology, the Fabry–Pérot sensing element is hermetically embedded in the core of the host single-mode optical fiber. The advanced design yields an all-fiber, ultra- compact, very-sensitive, and high-accuracy sensor ideally suited for precise strain or pressure measurements to 700 °C.

The TFP10 sensors have been applied to a large number of tests and measurements in the field and are reported to be uniquely positioned among the best fiberoptic high temperature sensors available today.

FBG based pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal.
