Manipulation manner null of the system for digital capacitance diaphragm gauge and the particular system which

摘要

The system and the method of controlling the sensor digitally. In a certain execution form, the digital controller for capacitance diaphragm gauge is imbedded the digital signal processor (DSP). The controller, sensor AFE (30) from through variable gain module, zero offset modules, and the analog - digital transmitter, receives the input which is digitalized. Scaling it does the controller, automatically the input which is received, with variable gain and adjusting zero offset modules. In addition the controller, in order to maintain appropriate temperature in the sensor, the heater assembly monitoring it does, adjusts. The controller utilizes the kernel module which allots the resource which is processed to the various tasks of gauge controller module.
