Designe dedicated for easy field operation

Network communication ability

Compact and lightweight. LCD touch screen interface
enables immediate access to measurement status.
Optical sensor signal can be converted into physicalquantity and displayed.

Capable of Wi-Fi connection (optional) in addition toLAN connection allows for command control and filetransfer etc., to expand its network connection ability.

* Conversion factor can be acquired from each SD card that comesalong with PF20 to transfer to it.

Easy additional deployments
of FBG sensor capacity
It accomplishes addition of FBG sensor deployments
conveniently as a result of multiplexer to expand
measurement channels up to 16CH.

Easy operation
Easy operation available through the use of “InstallNavigation” system without complicated manual
configuration.

2Higher sampling rate
Capable of data acquisition with 1ms max. highsampling rate.

Various measurement modes
Various measurement modes are available represented
by Triger function, Timer function etc.

FBG data logger features•Support feature for FBG sensor installation: Install navigation• It navigates FBG sensor installation though the use of “InstallNavigation” which conventionally has been difficult to achieve byuser.
• The feature achieves automatic optimization of configurations for
installed FBG sensor without complicated manual configurations.
• The feature allows for high reliable measurement due to its
capable of self-verification and diagnosis of installed FBG sensor.

•Variety of measurement features
Timer function

Easy output recognition from FBG sensor• Programmable timer
Maximum 4 parameters can be programmed for start
time of measurement and measurement time.

• Interval timer
User can set measurement time and its interval.
ex:10 minutes measurement time every one hour interval.

Trigger function

Physical quantity

Arbitrary FBG sensor output can be configured as a formof trigger output.

TimeWaveform•Variety of interfaces

Data can be stored for near trigger signal measurement*User can measure timer function coupled with trigger function.

• LCD touch panel in full color allows operation without having PC at field.
• Wi-Fi connection is available in addition to LAN connection allows for field operation throughout PC andtablet-type device.
• It features FTP server for the file transfer in addition to TCP/IP socket communication to allow for datatransfer from SD card.
