The T615 is an Accurate and Sensitive Single-Mode Fiber (SM) based Fiber Bragg Grating (FBG) based Packaged Pressure Sensor with integrated atmospheric pressure referencing for operation to 290psi (20 bar).

The patented novel transducer mechanism yields a reliable high sensitivity and absolute accuracy optical sensor. Ready for direct use in many applications. Calibration service available upon request. The T615 sensor handling and installation are fast, easy and intuitive. Delivers the advantages inherent to FBG sensors.

The T615 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 are possible and can be customized under contract. The T615 is self-temperature compensated and uses precision-made FBGs in a novel packaging architecture for producing a transducer configuration that enables measurements at a rate of up to 100Hz to 290psi with accuracy below 1% FS, and resolution of 0.1%FS. The customer can select the pressure range from our available listed options and the sensor will be built accordingly. The proven opto-mechanical architecture of the T615 and the advanced processing techniques used in producing this sensor yield a simple transducer configuration with both high linearity and repeatability. The sensor-to-liquid-surface integrated air vent and single or dual optical fiber pigtails cabling system make the T615 well suited for projects that include the need to monitor liquid pressures at one or many locations. Flat or cone-head M40 porous stone configuration options for the filter installable on the pressure head. Ruggedized for demanding projects requiring field-proven technologies that yield accurate and stable operation for the long-term. Suitable for operation in harsh environments to monitor the height of the liquid level in rivers, lakes, and the sea, the pore water pressure in soil, the liquid level in industrial tanks, and other applications.
