FBG interrogation monitor for diagnostics and monitoring
FBG interrogation unit FIU – 44 - 1.55 – 40 – x - A4 up to 4 kHz provides registration of optical signals from unified sensor heads based
on Fiber Bragg Gratings (FBGs) with a sampling frequency up to 4 kHz per second for one channel.
Data processing and visualization can be performed by the built-in computer with specialized software.
The distinctive features of the interrogation unit for process control are:
- the ability to transmit data via the Modbus protocol through various interfaces (Ethernet, RS485, RS232) to the user system;
- simultaneous measurement of a number of physical quantities (temperature, strain, pressure, load, etc.);
