FBGP Series FBG Pressure Sensor
(1)FBG Pressure Gauge
(2)FBG Earth Pressure Gauge
(3)FBG Osmometer
FBGP Series Pressure Sensor developed by Beijing Pi-Optics Co. Ltd can build the quasi-distributed sensing network(ten to hundreds of units). It has the advantages of high resolution(0. 01%FS), wide pressure measurement range(0~250MPa) and operation temperature range, anti-electromagnetic interference, anticorrosion, antibounce, anti-aging, and long lifetime during. It is the ideal component for the pressure measurement in geotechnical engineering.

FBGD Series Displacement Sensor
(1)FBG Displacement Sensor
(2)Contact Type FBG Displacement Sensor
FBG Displacement Sensor with 0.1m to meters of measurement range can be divided into pull type and probe type. It can accurately measure the distortion and slippage of the tunnel, dam and side slope.

FBGS Series FBG Strain Sensor
(1)Super-high accuracy FBG strain sensor
(2)Surface Mounted FBG Strain Sensor
(3)FBG Armor Plate Strain Sensor
(4)Point Weld FBG Armor Plate Strain Sensor
(5)Embedded FBG Strain Sensor
(6)Adhesive Type FBG Strain Sensor
FBGS Series FBG Strain Sensors developed by Pi-Optics can build the quasi-distributed sensing network (tens to hundreds units). It has the advantage of high resolution (<1ue), wide strain measurement range (+/-3000ue), anti-electromagnetic interference, anticorrosion, ant-bounce, anti-aging, long lifetime during. There are surface mounted and buried types. It can be wildly used at bridge, dam, oil pipe and other mechanical structure long time health monitoring, or used as sensitive component directly buried in the intelligence material

FBGT series Temperature Sensors
(1)Surface Mounted FBG Temperature Sensors
(2)Embeded FBG Temperature Sensors
(3)Immerged FBG Temperature Sensor
FBG Temperature sensor designed and developed by Beijing Pi-Optics Co., Ltd has the great feature of quasi-distributed sensor network(hundreds of units), high sensitivity(0.1'C~0.5'C), wide temperature measurement range (-100'C~+300'C), no zero point drifting, anti-electromagnetic interference, anti-corrosion, high temperature resistant. The sensors can be widely used in the civil engineering, electric power system and petrochemical industry.
