Precise, Compact and Cost-Effective

FiSpec FBG X1000

Compact, precise and fast fully-integrated FBG Interrogator with embedded light source, on-board processing and simultaneous streaming of up to 24 wavelength, strain or temperature values at up to 2kHz. Rugged engineering based on advanced materials ensuring first-class thermal, vibrational and polarization stability for accurate fiberoptic measurements.

Precision and Accuracy at your Fingertips

Ultra-precise Strain Sensing

The X1000 takes Strain Measurements with FiSpec Interrogators to the next level. With a typical precision better than 1μm/m (@1kHz, σ) even smallest stresses or loads become clearly visible.

Like all FiSpec Interrogators the X1000 simultaneously measures all FBG wavelength shifts along the optical fiber with high linearity and absolute accuracy.

Precision and Accuracy at your fingertips

Multipoint Vibration Sensing

With a maximum sampling speed of 2kHz the FiSpec X1000 enables you to anaylze even fast vibration patterns or react immediately on critical events. The high-speed streaming mode guarantees a simultaneous read-out of all FBG sensors with a stable timing without any dark times nor missing frames.
