The gage design is flexible enough to allow for easy attachment to various substrates, making measurements on metal, concrete and other surfaces straightforward. The two FBG sensors that comprise the os5100 gage are located within the rugged hard-coat anod- ized aluminum enclosure which shields them from the elements and allows for installa- tions in harsh environments os5100 Displacement Gage with integrated junction box (shown without cover) This gage can be used alone or in series as a part of an FBG sensor array (which may nclude strain and temperature gages, accelerometers and other displacement gages) Cabling for such arrays is much less expensive and cumbersome than comparable elec- tronic gage networks. Cables can be joined directly inside the enclosure, eliminating the need for separate junction boxes. The os5100 delivers the many advantages inherent to all FBG based sensors, including EMI immunity - something vibrating wire gages can- With each gage, Micron Optics provides a Sensor Information Sheet listing the gage factor and calibration coefficients needed to convert wavelength information into engi- neering units. Micron Optics' ENLIGHT Sensing Software provides a utility to calculate and then record, display and transmit data for large networks of sensors.

Displacement Gage | os5100 g°°°g , Angle Bracket Mount - sa5101 The sa5101 Angle Bracket Mount provides convenient, secure attachment of the os5100 gage probe to your structure. Slotted holes in both the base and vertical leg allow alignment during installation The sa5102 Safety Disconnect is a magnetic breakaway device that helps to protect the os5100 Displacement Gage from dam- age if there is a risk of exceeding the travel limit. Should the substrates being monitored return within the proper range the sa5102 will automatically reconnect. The sa5103 Universal Joint compensates for misalignment...
