Pressure protection is good for pressure transmitters or pressure switches.
Two different roles, at the same time both better
If your protection value is fixed, do not need to adjust, then the use of pressure switch more economical and practical. If your protection value changes frequently, today is 30MPa, tomorrow is 20MPa, then in this case, or with a pressure transmitter is good, but also with the pressure transmitter can display the pressure value, in the adjustment and use of an intuitive Sense, know what to put pressure is better. And with the pressure switch can only feel the.
Boiler steam pressure protection, two colleagues with the best results.
If you consider the cost of the problem can add one or two pressure switch.
Pressure switch can be directly connected to the protection circuit, low price, fast response, high reliability, simple structure;
If not show the demand, with the transmitter will only increase investment, reduce the effect;
Large power plants, petrochemical companies usually require protection of the circuit control points must use a separate signal switch. Need to use two sets together.
