The T310 is a high-shock proof, wide frequency range, high-accuracy single-mode Fiber Bragg Grating Packaged Accelerometer for use in environments from -20°C to +80°C.
Available in a wide range of optical specifications. Packaged to eliminate influences from the ambient environment, the patented transducer mechanism yields high sensitivity to resonance frequency ratio. Ready for direct use in many applications. Calibration service available upon request. The full-scale (FS) accuracy, resolution, and precision specifications are guaranteed only when used with FAZ TECHNOLOGY instruments. The T310 sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG based sensors.
The T310 series Accelerometers are fabricated using licensed and proprietary state-of-the-art laser manufacturing technologies and product designs. The sensor packaging described herein represents the most popular configuration and can be customized.
Measurements down to 0 Hz (static) The T310 uses ultra-precision made FBGs written into the fibers’ core and a patented packaging architecture for producing a transducer configuration that enables measurements to 0 Hz without loss of sensitivity or phase flatness. At 0 Hz the sensor operates as a tilt sensor.
Advanced performance, form-factor and multi-axis options available. The T310 accelerometer configuration specified herein is the most common configuration. Other frequency ranges, sensitivities, resolutions, shock levels, and form-factors available, including integrated component packaging for two and three axes accelerometers.
Ready to install on 3 axes and be daisy chained. Well suited for projects monitoring accelerations at one or many locations. Sensor body provides holes for mounting it on any of the three orthogonal axes. Delivered as double-ended connectorized sensors or in ready to install arrays of various lengths and number of sensors. Up to 30 accelerometers per sensing array. Typical arrays include daisy chaining with other sensors including T210-T250 strain, T510-T520 tilt, and T810-T820 temperature sensors.
Reliable and field proven. Designed and ruggedized for demanding projects that require filed proven, accurate and stable operation for the long-term. Extensively used in marine, geotechnical, civil engineering and other commercial projects since 2012.
Applications in Structures, Machines, Geotechnical, Security, and R&D MonitoringT320 / General Purpose Accelerometer Calibration
Each T310 FBG Accelerometer can be provided with our optional factory Calibration Certificate. The table below provides an illustrative example of the typical data included in the certificate:
The following calibration formula can be used to convert the sensor wavelength output to vibration. The T310 sensor is not temperature compensated and therefore the FBG offset will need to be adjusted to the current value prior to use by performing a 0g measurement. Alternatively the sensor output can be analyzed in the frequency domain by means of the Fourier Transform and in this case the use of the offset value can be omitted. The values in the table below are representative examples.
T310 Accelerometer Transfer function example: Serial Number ID 11090-01 Ref @ 0dB = 5.00pm/g
The T310 accelerometers are tested on a shaker table using flagship FAZT I4G ultra precision sensing interrogators and compared to a B&K 4506B reference sensor. The testing setup has an effective testing range of 30-2000 Hz. Sensor performance between 0-30 Hz is flat.
Customer specific sensor tests:
Application specific customized testing can be performed upon request. Engineering lab service charges may apply. Custom work requires a Scope of Work document and a mutually agreed upon project timeline.
T310 Accelerometer Dimensions:
The sensor’s standard dimensions are provided herein.
It should be noted that while most often the customers’ application related physical requirements can be met by our standard accelerometer configuration, the internal patented transducer mechanism can be adapted to yield dramatic changes in outside dimensions and to pass various levels of ruggedization to meet and exceed even the most demanding field installation requirements. The T310 sensor is ROHS, REACH, CE, and ATEX compliant.
