What is the difference between a pressure sensor and a pressure switch?
The pressure sensor can continuously change the pressure value into an analog or digital signal to the controller, the function is more perfect, but the price difference is several times. We use some of the water pressure switch dozens of dollars to a hundred dollars, the sensor needs at least six seven hundred one.
Pressure switch is simple, generally transferred to a fixed value, at least there is a difference, according to the circuit wiring, can be higher than this pressure or less than when the controller to an electrical signal, and then make a judgment.
The pressure switch is a simple self-control electrical switch, commonly used in simple electrical equipment for the detection of pressure signals, the output is the switch, such as water heater on the water pressure switch, when the water pipe to reach the pressure switch action Value when the pressure switch action, the water heater to get the signal before starting work to prevent the water heater dry.
The pressure sensor is to convert the pressure value into the corresponding analog or digital electrical signal, as the pressure automatic control device input signal, the pressure automatic control device according to the input signal and the original set control the corresponding output device control pressure to achieve accurate Automatic control of the purpose of pressure.
