1. A Wireless Sensor and Control Transmitter System for a hydraulic system controlled by a controller unit, comprising:

  • a master module unit having electronic circuitry that communicates with a hydraulic system controller unit and also communicates wirelessly with a field module unit, the field module unit further having electronic circuitry that communicates with one or more field electromechanical control devices or sensors, wherein the circuitry of the master module unit is capable of encrypting command signals from the controller unit into digital signals and wirelessly transmitting the digital signals to the field module unit, the field module unit circuitry is capable of decrypting the digital command signals received from the master module unit to reproduce the controller command signal and of transmitting the reproduced signal to the field electromechanical control devices or sensors, and the circuitry of the field module unit is capable of converting signals from the sensors into digital signals and wirelessly transmitting the digital signals to the master module unit, and further the master module unit circuitry is capable of converting the digital signals received from the field module unit to reproduce the sensor signals and transmit them to the controller.
