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: How to determine the car air conditioning pressure switch is good, or bad? What are the steps and methods of operation?: Then take the table to see if there is no system pressure 0.5M, if any, directly with a multimeter Ohm file pressure switch off the situation, no resistance is good, there is bad ? The answer was

Q: Great Wall dazzling air conditioning pressure switch and the same as the car: 1, the pressure switch is to control the compressor and expansion valve and the pipeline between a pressure regulation.

Q: Switch mechanical pressure switch and electronic pressure switch what is the difference: Electronic pressure gauge and mechanical pressure gauge, of course, there are differences, such as electronic pressure switch KP46P-02-F1, mechanical KP1-3-01-03-PT, installation in different ways, different performance, the pressure switch is Applicable to the day line, STAR, small oblique arm machine robot industry, such as {Dongguan days where pneumatic} have to provide this pressure gauge

Q: Car air conditioning compressor pull, but the fan does not turn, with the pressure switch has a relationship? why?: Probably a circuit problem search Asked If the high voltage switch is faulty, will not cause air conditioning fan does not turn? To answer Generally not,

Q: What is the principle of automotive air conditioning pressure switch: Air conditioning pressure switch usually has three lines, a 12v. The other two are a high voltage switch, one is the atmospheric pressure switch, the pressure is too high will disconnect the compressor electromagnetic clutch, when the high pressure side of the pressure is higher than a certain value, high voltage switch It opens, so that the fan high-speed turn, not because of high pressure damage to the system

Q: What is the oil pressure switch?: Not called the switch, called the sensor more standard We often call the popular call sometimes call pressure switch

Q: Pressure switch dead zone adjustable, dead zone is not what it means. Please explain in detail Thank you.: Dead zone, DEAD ZONE, in the field of instruments, also known as the instrument of the insensitive area. The change in the amount of input does not cause a limited interval (also understood as sensitivity) of any appreciable change in the output of the instrument. The cause of the dead zone is the friction between the internal components of the instrument and intermittent.

Q: Only set the fire tank regulator, there is no regulator of the temporary high-pressure water supply system, the pressure switch how to set the pump pressure?: then look at how much the floor, the pressure switch is placed Alarm valve above, is the spray pump, not the regulator with the pump.

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.
