Description

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 T620 series Pressure Sensors are fabricated using licensed and proprietary state-of-the-art laser manufacturing technologies and product designs. The pressure sensor configuration specified herein is the most common configuration. Other pressure ranges, sensitivities, resolutions, and form-factors are possible and can be customized under contract.

Key Features:

Accurate measurements to 150 psi. The T620 uses ultra-precision made FBGs written into the fibers’ core and a novel packaging architecture for producing a transducer configuration that enables measurements to 150 psi without loss of sensitivity or accuracy.

Self-Temperature compensation. Each T620 pressure sensor includes two internal FBGs and is self-temperature compensated for true plug and play operation in the field.

Excellent linearity. The proven opto-mechanical architecture of the T620 and the advanced fiber to steel bonding techniques used in producing this sensor yield a simple transducer configuration with both high linearity and repeatability.

Ready to be daisy chained. Well suited for projects that include the need to monitor pressures at one or many locations. Provided as double-ended connectorized sensors or in ready to install arrays of various lengths and with a flexible number of sensors. Available with up to 30 pressure sensors per sensing array. Typical arrays include daisy chaining with other sensors including T210-215 vibration, T220-240 surface and embedded strain, T310-330 acceleration, T510-520 tilt, and other FBG sensors.

Reliability by design. Ruggedized for demanding projects requiring field proven technologies that yield accurate and stable operation for the long-term. Designed by Civil Engineers for Civil engineering applications.

Applications:

Civil Engineering, Geotechnical, Energy, and R&D Monitoring
