Advantages and disadvantages of intelligent pressure switch and mechanical pressure switch

Such as title, today to talk about the advantages and disadvantages of these two kinds of pressure switch, with the development of science and technology, the progress of technology, intelligent pressure switch has entered the eyes of your customers, but also more and more involved in. Intelligent pressure switch with the previous mechanical pressure switch on the contrast, what are the advantages and disadvantages of these may be confusing customers.

Intelligent pressure switch

First display accuracy

Intelligent pressure switch: 0.3%FS, 0.5%FS, 1%FS, 1.5%FS

Mechanical pressure switch: panel display

Second repeatability error

Intelligent pressure switch: less than or equal to 0.5%FS

Mechanical pressure switch: less than or equal to 1%FS, less than or equal to 1.5%FS

Third seismic resistance

Intelligent pressure switch: good shock resistance

Mechanical pressure switch: relatively poor seismic performance, because it is oil filling

Fourth set operation

Intelligent pressure switch: power up, zero pressure state can be operated by buttons, set the range is the full range of

Mechanical pressure switch: the need to pressure to the specified pressure, the use of screwdriver set, set the range: 20%-80%FS

Fifth contact type

Intelligent pressure switch: PNP, NPN/ solid state relay; this type of contact will not produce the arc, contact carbon deposition, etc.

Mechanical pressure switch

Intelligent pressure switch

It said the advantages of the intelligent pressure switch, then it's disadvantages, first of all, wiring complexity is greater than or equal to 4 roots, the need to use the power supply, there may be a strong interference.
