Embedded multi-parameter monitoring system for Submersible electric pump

The multi-parameter measurement of submersible electric pump is an important part of monitoring data underground. The system measures the temperature, pressure, leakage current and vibration signals, which return through the power line carrier technology and data processing on the oil well. This article also focuses on the pressure sensor temperature compensation algorithm, using an anti-linear curve fitting to approximating, and effectively eliminates the error of silicon pressure sensor resulting from temperature changing. The system has brought about a striking effect in experiments of oil field.
