Control system for oil product detecting instruments

The invention relates to a control system for oil product detecting instruments. The existing detection system for oil product detecting instruments is complex in structure and has fewer functions, other functions can only be achieved with the aid of other detection devices, and therefore, space is wasted, and the accuracy of detection is affected. The control system for oil product detecting instruments comprises a CPU, an A/D circuit, a signal amplifying and conditioning circuit, an error amplifying circuit, a front-end signal processing circuit, a signal amplifying and conditioning circuit, a storage device, a data transmission interface, a power supply circuit, and an alarm circuit. The A/D circuit, the storage device, the data transmission interface, the power supply circuit and the alarm circuit are connected with the CPU. The front-end signal processing circuit, the error amplifying circuit, and the signal amplifying and conditioning circuit are connected in sequence. The signal amplifying and conditioning circuit is connected with the A/D circuit. The control system of the invention has a simple structure, and an oil product detecting instrument manufactured by using the control system has a small size.
