Six important notes on electronic pressure switches

Problem one: the working principle of the electronic pressure switch.
Working principle of electronic pressure switch: Is when the pressure in the system is higher or lower than the rated pressure, the safety of the discs in instantaneous induction electronic pressure switch, by connecting rod drive switch connector on or off, when the pressure drop to or the raising of the rated value when the disc is instant restoration, automatic reset switch, or simply, when the measured pressure exceeds rating, displacement of the free end of the elastic element, Push the switch element directly or after comparison to change the on-off state of the switch element to achieve the purpose of controlling the measured pressure. The elastic components used in electronic pressure switches are single coil spring tube, diaphragm, membrane box and bellows, etc. The switching components include magnetic switch, mercury switch, micro switch, etc.

Problem two: electronic pressure switch composition.
1 Sensor pressure differential pressure temperature liquid level collection component
2 Stable, low temperature drift amplifier circuit
3 A/D conversion module

Problem three: electronic pressure switch problem.
Anti-interference is a factor that affects the use of electronic pressure switches. Our company has devoted 4 years of research and development in this respect, and finally successfully overcome this problem. Details can be click: "Intertek" all electronic pressure switch introduction view.

Problem four: Comparison of electronic pressure switch and mechanical pressure switch.
Compared with mechanical pressure switch, electronic pressure switch has the advantages of high precision, good repeatability, long life, no contact, strong corrosion resistance, flexible and convenient setting, intuitive display, low temperature drift and so on. For more details, see our previous article: Comparison of Electronic and mechanical pressure Switches.

Question five: Comparison between electronic pressure switch and similar products.
1. The model recognition technology is adopted to overcome the abnormal pump swing caused by the action of the pressure switch when the pressure of the existing pressure switch is extremely low at an instant.
2. The process selection switch is added, and different thresholds can be set for the adjacent tank flow and the closed flow. The threshold set for the adjacent tank flow can be appropriately reduced, thus solving the problem that the pressure switch of the adjacent tank flow cannot be put into use.
3. A calibration button is added. As long as the "calibration button" is pressed during the calibration of the intelligent electronic pressure switch, the microcomputer will automatically memorize the current pressure value and take the value as the setting value of the "intelligent electronic pressure switch", so as to realize the test of the pressure switch.

Question six: electronic pressure switch related terms and introduction.
Has to introduce before the terminology of pressure switch electronic pressure switches and mechanical term is the same as the pressure switch, mainly is the pressure, precision of full scale (F.S), take off bad (dead zone), temperature, S.P.D.T (single pole double throw), D.P.D.T (double pole double throw), cap of a contact (normally open), the lower limit of the contacts (normally closed), Upper and lower bounds HL, upper bound 2, Lower bound 2, IP (Protection level).
