Deltasens r&D interrogator
DeltaSens is the solution for multiplexing Fabry-Pérot sensors while maintaining high sensitivity and acquisition speed. In combination with our fiber-top technology, it supports the measurementof a broad range of physical parameters such as accelerations, pressure, humidity, temperature, and even gas concentrations.
DeltaSens provides a very affordable solution without compromising on
the sensitivity. The distance between the sensors and/or read-out can vary from centimeters up to several kilometers.
DeltaSens uses interferometry to measure multiple low-finesse Fabry-Pérot sensors, and therefore provides a reduced cost per sensor.
DeltaSens R&D system works seemless with 2600 series accelerometers.
17 kHZ sampling
Lan interface, remotely accessible
online data processing
no maintenance, easy to use
DeltaSens, based on optical fiber interferometry, offers a completely new way of multiplexing Fabry Pérot type sensors. Fabry-Pérot sensors are the most sensitive optical transducers with the smallest dimensions. With DeltaSens, a high sensitivity sensing network in a challenging environment becomes reality.
All sensors in the network are sampled simultaneously, such that synchronization-sensitive correlation studies can be performed. The signals of each sensor are based on measuring phase information of the sensor cavity sizes; by tracking this phase over multiple interferometric fringes a large dynamic range is achieved.
Using just a single readout to measure multiple MEMS based Fabry-Pérot sensors makes DeltaSens an affordable solution, without compromising on the sensitivity or bandwidth.
