We developed this product is that we mainly consider the relationship between the pressure and flow rate, and combine

the data analysis, to achieve better control effect.

Structure: Combine photoelectric Principle with flow switch. It consists of water sensor, pressure sensor and control site.

Wide voltage design. Double control of pressure and water. Security is higher.

Function: Double control of pressure and water. Pressure control can be used alone. It has water shortage protection

function, water automatic judgment function, preventing sticking function, low voltage protection function.

Q: What is the principle of automotive air conditioning pressure switch: Hello! Pressure switch is to detect the pressure of air conditioning pipelines, and then the pressure signal sent to the air conditioning control system, play a role in protecting air conditioning compressors and piping! Only the pressure signal in the normal range, air conditioning can work properly!

Q: How does the pump pressure switch adjust?: Because the switching power supply, battery or battery current is large, but on behalf of the power supply can provide the current capacity, the actual work of the power supply current is not always the maximum power to provide the power supply, but depends on the pump load size; Large, need to provide power to the pump current is large; otherwise small. Give a very appropriate example: Assuming raised 50 kg of heavy things, need to eat 2 bowls of rice, and A appetite up to 3 bowls, B appetite up to a bowl, if A eat 2 or 3 bowls of rice this Something certainly no problem, but if replaced by B, can not lift the weight

Q: How does the pressure switch work?: A: No. Switching power supply with the main parameters of the pump is the most close to the output voltage and output current. To pump the normal work, you need to output voltage and pump the same voltage, such as 12V DC; power output current than the pump maximum working current

Q: SMC pressure switch "reverse" What does it mean? Negative output when?: In fact, the output signal is often open the meaning of normally closed

Q: Pc5 pump pressure switch how to adjust the pressure: If the power supply current ≤ pump maximum operating current, but there will be because the power supply power is not enough lead to micro pump parameters are not enough (such as flow, pressure smaller, etc.).

Q: After the power, display E1, to determine the sensor circuit problems, dismantling and found that one foot of the relay was blown off, replace the bad relay, and then power, show E4, to determine the pressure switch failure, I as a maintenance beginner, Once encountered such a failure, how to determine the pressure switch is good or bad, how maintenance?: Look at the instructions to determine that you device Measured with a multimeter

Q: No tower water supply pressure switch problem: To the two pressure to stop, to a pressure to start, I want him to 0.5 or lower pressure in the start how to tune? The pressure switch is an adjustment nut.: 0.5MPA Han concept you know no, the pressure can be vertical up nearly 50 meters, say how much your pressure tank, rust is not safe point!

Q: The three terminals of the fire pressure switch are not a common point, a normally open point, a normally closed point, the specific how to pick up the pump, how and fire linkage: The description of the pressure switch is correct, then open the point, with the input module to take the signal, through the fire mainframe linkage start the spray pump.

Q: Before we do fire linkage is only linkage signal valve, but suddenly see some of the drawings are also linked to the pressure switch, ask, what is the pressure switch with the shower signal valve is what ah! Do you need to activate the pressure switch after the linkage signal valve?: The linkage signal valve also need to linkage after the pressure switch, because the linkage valve to start the sprinkler system after the spray system will drop the pressure, the pressure switch will start the pressure pump to the sprinkler system

Q: Pump pressure switch 0.3 stop, 0.1 start. Want to tune to 0.3 stop, 0.2 start how to tune?: I also want to buy this pressure switch, if it is online to buy, can give a shop?
