MOVELASER Wind Speed Anemometry Mast Fiber Bragg Grating Sensor

Demodulator performance parameters Wind speed accuracy 5%～95%RH

1,Product introduction

Theoretical measuring point position: find the nameplate of the zero scale line on the end face of the pitch bearing or the connection between the blade and the bearing, and draw an extension line perpendicular to the zero scale line on the end face of the bearing with a box ruler and a marker, and extend through the baffle at the root of the blade to the distance from the bearing. The end face baffle is about 1% to 3% of the blade length, and must be installed on the cylindrical section of the blade, and pay attention to avoid end face bolts, mold joints and reinforcement surfaces (Note: In this example, 1.5m is taken. Counting from the board, it is generally about 0.7m, subject to the actual measurement), make a mark, and draw a "cross" line at the measuring point (sensor installation location) (as large as possible to avoid grinding off), and the measuring point is The datum divides the circle on the circumference 1.5m away from the bearing end face into three equal parts, and marks them respectively.

5,External interface of demodulator

LAN: network interface, which can be used for the connection of the device network; the network cable can be connected to the computer, and the device parameter setting, status observation and data transmission can be performed through the device client software.
CANopen: CAN interface, which transmits data externally through the CANopen protocol.
POWER: Power interface, which supplies power to the whole device.
1-16: Sensor interface, used to connect with different fiber grating sensors (the number of channels is customized according to customer requirements).
FIELDBUS: DB9 interface, supports external data transmission through Profibus, RS485, etc.
