Six important points regarding electronic pressure switches: Point 1: The working principle of electronic pressure switches. Working principle of the electronic pressure switch: When the pressure in the system is higher or lower than the specified safe pressure, the disc inside the electronic pressure switch moves instantaneously. This movement, through the connecting rod, causes the switch contacts to close or open. When the pressure returns to the specified normal value, the disc returns to its original position instantly, and the switch resets automatically. In simple terms, when the measured pressure exceeds the specified value, the free end of the elastic element moves, directly or after comparison, to act on the switch element and change its on/off state, thereby achieving control over the measured pressure. The elastic elements used in electronic pressure switches include single-coil helical springs, diaphragms, bellows, and corrugated tubes. Switching elements include magnetic switches, mercury switches, microswitches, etc. Question 2: The components of an electronic pressure switch. 1. Sensor components for measuring pressure differences, temperature, and liquid level. 2. Amplification circuits that are highly precise, stable, and exhibit low drift. 3. A/D conversion module.

Interference resistance is the most important factor affecting the use of electronic pressure switches. Our company has dedicated 4 years to research and development in this area, and has finally succeeded in overcoming this challenge.

Question 4: Comparison between electronic pressure switches and mechanical pressure switches. Compared to mechanical pressure switches, electronic pressure switches offer advantages such as higher precision, better repeatability, longer lifespan, no contacts, superior corrosion resistance, flexible and easy setting, intuitive display, and low temperature drift. For more details, please click to read the article we previously shared: Comparison between electronic pressure switches and mechanical pressure switches. Question 5: Comparison of electronic pressure switches with similar products. 1 Model recognition technology was employed to overcome the issue of abnormal pump shutdown caused by the operation of the existing pressure switch when the pressure drops to extremely low levels. 2. A process selection switch has been added; different thresholds can be set for the bypass tank process and the sealed process. The threshold set for the bypass tank process can be lowered appropriately, thereby resolving the issue of the pressure switch not functioning in the bypass tank process. 3 A calibration button has been added; when calibrating the smart electronic pressure switch, simply pressing the “Calibration Button” causes the microcomputer to automatically remember the current pressure value, which is then used as the set value for the “smart electronic pressure switch”, thereby enabling the calibration of the pressure switch. Question 6: Terms related to electronic pressure switches and an introduction to them. We have already introduced the terms related to pressure switches earlier; the terms for electronic pressure switches are similar to those for mechanical pressure switches. The key aspects include voltage tolerance, accuracy, full scale (F.S.), break-before-make difference (dead zone), operating temperature, S.P.D.T (single pole double throw), D.P.D.T (double pole double throw), upper limit contact (normally open), lower limit contact (normally closed), two contacts for upper and lower limits (HL), two contacts for the upper limit, two contacts for the lower limit, and IP (protection rating).
