The IFOS I*Sense™ 48K offers a cost effective, high-speed, lightweight and small footprint solution for monitoring up to 32 Fiber Bragg Grating (FBG) sensors.

Key features and benefits of the IFOS I*Sense are:

The I*Sense provides simultaneous data display and storage for all its channels with every FBG seeing the full bandwidth, offering high precision, remote monitoring, long life, large dynamic range, and high measurement range with multiple optical bands available for expansion. Different sensing elements can be deployed on a single optical fiber enabling a mix of strain, temperature and derivative measurements for e.g. displacement, tilt, pressure, chemical and biochemical measurements, to best meet varying customer needs at a series of discrete locations.
