Compressor control systems capable of increasing the reliability and uptime of air compressor systems that operate in harsh corrosive outdoor environments by redundantly sensing one or more operating parameters of the air compressor systems. Such a compressor control system includes a controller adapted to monitor at least a first operating parameter of a component of the air compressor system, at least first and second sensors that are physically separate and spaced apart from each other and that redundantly sense the first operating parameter of a component of the air compressor system, and separate and independent wiring harnesses electrically connecting the first and second sensors to the controller.

The present disclosure provides a device for monitoring oil pressure in an oil cylinder of a diaphragm compressor, including a piston rod and a strain gauge circuit. The strain gauge circuit includes a strain gauge component and a bridge circuit connected, and the strain gauge component is arranged on the surface of the piston rod. A strain gauge component is noninvasively arranged on the piston rod of the diaphragm compressor to measure the load of the piston rod, such that the oil pressure can be measured indirectly, and thus the oil pressure of the diaphragm compressor can be measured nondestructively. Nondestructive and noninvasive monitoring of the diaphragm compressor is safe and reliable, and can achieve accurate monitoring of the oil pressure especially in high-pressure working conditions.
