Transmission Line Robots DLR SENSOR
If you're in need of transmission line robots dlr sensor to help with your business, please be free to buy with our factory. As one of the leading such manufacturers in China, we will offer you low price and unmatched services.
The Multi-Dimensional Conductor Sensor is a low-power, high-precision sensor based on 4G communication. It measures conductor sag, conductor galloping, and conductor wind deflection, as well as conductor temperature and conductor current.
It integrates a GNSS module for GPS positioning and time synchronization.
It includes a 485 expansion interface for measuring ambient temperature, humidity and light intensity.
Built-in rechargeable lithium battery: 9.6 V, 3 Ah. Battery expansion is available upon request.
Optional 2.4 GHz module for use as a 2.4 GHz terminal.
Built-in Rogowski coil for conductor current measurement. The coil output is amplified and converted into a proportional electrical signal. The system calculates the current via AD sampling and dedicated algorithms.
