pressure switch
Thread Content
Has anyone ever used a pressure switch with upper and lower limits, one normally open node and one normally closed node? Which manufacturer is better?
Sor, Nagano, Yokogawa, Taiping, ITT,
I think ROUSEMOUNT is useful
Pressure switches are not expensive to import. E+H and Rosemount are all good, but E+H is relatively cheaper.
E+H is very good, the manufacturer recommends it well, and the results are good.
French Burton is also good. . . . . . . .
The technical content of the pressure controller is not very high. If it is not micro-pressure, it can be made domestically (to expand domestic demand). The selection depends on the measured medium, temperature and other parameters.
The upper limit of pressure is 0.5MPA and the lower limit is 0.45MPA. Can a pressure switch be used for pressure control?
Nagano, Yokogawa, E+H, Rosemount, E+H are very good, cheap, cost-effective, and good in use.
When choosing a pressure switch, you have to provide the medium and temperature. If the medium is clean and the temperature is not high, it will be cheaper to choose a domestic or imported switch that is used in more commonly used fields (such as DWYER commonly used in the HVAC industry). If the conditions are harsh, it is better to choose SOR, UE, BARKSDALE, etc.
The American UE is pretty good. We have used it a lot, but there is a problem. Its equipment is not suitable for use in micro-differential or micro-pressure situations.
We have used Shanghai Far East, which is also good. Now it’s UE’s
Most of us here use UE, and the quality is pretty good.
Sanwu's is very good and cost-effective
