Product overview
The design principle of the CYG3002 digital intelligent pressure switch is manufactured using MEMS technology. The silicon piezoresistive pressure sensor with precise temperature compensation is a pressure-sensitive element. The elastic diaphragm is a silicon membrane when it works. The maximum displacement is in the order of sub-micron, so there is no wear. No fatigue, no aging. The service life is more than 107 pressure cycles. Highly reliable digital circuits are used to complete the signal processing from the sensor output to the switch output that can set the alarm pressure value arbitrarily, and to complete the intuitive digital pressure display that is convenient for user adjustment. That is, the digital pressure instrument and transmitter technology are organically combined to convert the pressure signal sensed by the pressure sensitive element into a switch signal output. That is, it integrates pressure measurement, display and control, making it easy to use.
The design of CYG3002 digital display intelligent pressure switch breaks away from the principle of analog signal comparison output used by traditional electronic pressure switches. It solves the problem that the output high and low levels are unstable due to the results of analog comparison, the relay frequently jitters, and the control accuracy is low, which gives the entire Control brings great inconvenience and other problems.
