The IFOS I*Sense D24K interrogator offers a cost effective, lightweight and small footprint solution for monitoring up to 160 Fiber Bragg Grating (FBG) sensors.

Key features and benefits include:

The I*Sense® D24K interrogator provides simultaneous data display and storage for all its channels with high precision, autocalibration, remote monitoring, long life, large dynamic range, and high measurement bandwidth. Different sensing elements can be deployed on a single optical fiber, enabling a mix of strain, acceleration, displacement, tilt, pressure, temperature, and other types of sensors including chemical and biochemical sensors, to best meet varying customer needs at single locations or a series of locations. Customized sensors are available upon the customer’s request.
