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:Is the pressure switch used?: Pressure switch is a commonly used switching instrument, in a number of industries have a certain application. It controls the flow of traffic and block, this switch is very important. The following are the same as the " Reference: Baidu search Ai Chi mall, inside the knowledge base has a very comprehensive industrial learning materials and complete product solutions, but also to meet your procurement Please also please, thank you

Q:What is the difference between a pressure switch and a pressure transmitter?: Pressure switch: When the system pressure is higher or lower than the rated safety pressure, the sensor inside the disc instantaneous movement, through the connecting rod to push the switch connector connected or disconnected, when the pressure dropped to or rise rated recovery The switch is automatically reset, or simply say that when the measured pressure exceeds the rated value, the free end of the elastic element displacement, directly or after comparison to push the switching element, change the switching element on-off state , To achieve the purpose of controlling the measured pressure. The pressure switch uses elastic elements such as single-ring spring tube, diaphragm, diaphragm and bellows.

Q:Air conditioning pressure switch damage will be what failure: Usually the pressure switch is connected to the compressor power supply, if damaged, one situation is the compressor can not work, the other case the compressor will always work, even if the system pressure is too high, if the system pressure is too high, and compression Machine to continue working, then easy to damage the compressor.

Q:How is the pressure switch selected?: For electronic pressure switches, please confirm the following parameters Range 2. Switch range 3. Accuracy 4. The number of switches 5. Switch function: normally open normally closed (PNP or NPN output) 6. Interface size 7. Medium temperature 8. Electrical connection 9. Degree of protection Please note the difference between the two 1. Switch function: mechanical switch than the electronic switch more than a single pole double throw function 2. Load power: mechanical switch load than electronic to large, 3. Application: mechanical pressure switch can be directly connected to the circuit, or with the relay used, while the electronic pressure switch directly output switch signal, and the need for external power supply. 4. Price: mechanical pressure switch is cheaper than electronic

Q:Air compressor pressure switch on the edge of the hole leak, can be normal inflatable, but also their own power, that is, has been leak: Bad joints caused by the bar Turn off the power to release the internal compressed air removed after the RBI raw tape installed on it.

Q:I have a pressure switch on the cylinder where the air pump and pump are connected. When the pressure in the cylinder reaches 4KG, the pressure switch will be automatically disconnected and the pump will be shut down. The air pressure will drop to 2KG. The question now is: the pressure switch is 24V, the pump is 220V, please master guide how to connect this switch and air pump to control the off? Thank you Please try to say that some, I am not engaged in electronic electrical, afraid to understand do not understand. Also do not want to change the 220V pressure switch, because the hands of the cylinder is the original, screwed in the cylinder reserved hole, very small, as shown Or is this a pressure sensor? Seek expert guidance to provide programs: Look at the picture, are you a stress sensor? Asked I do not know Taobao to buy. The Seek guidance

Q:Import Touareg air conditioning pressure switch where: The role of pressure switch: by monitoring the pressure of high and low pressure to control the compressor work and stop (not an air conditioning compressor has been on), low pressure can not be lower than the specified value, high pressure can not be higher than the specified value, or cut off the compression Machine powered. High voltage switch also has a role: connected to the radiator fan high gear.

Q:Car 4-wire air conditioning pressure switch principle, 4 lines were then received there, and the role.: Low-voltage switch control air conditioning pump work or not, and high-voltage switch is to control the high-speed fan. Please refer to the 2 valve and 5 valve air conditioning system circuit diagram. Four-wire pressure switch works are the same, About two high and low pressure switch, the upper and lower pressure switch;

Q:Where is the pressure switch?: my machine is to use this pressure Table, the feeling can be right, no defense, you can try trial

Q:Santana air conditioning pressure switch is the four lines that then: On the dry bottle, the green color is 1, the air conditioner relay output line 2, is to the compressor power cord, red 1 is the output line, 2 is the cooling fan relay control line; Two high voltage switch two low voltage switch, high pressure control fan, low pressure control compressor, low pressure normally closed high pressure normally open; Pressure switch is the air conditioning above the double pressure switch, installed in the air conditioning on the high-pressure pipeline; Some models are equipped with two pressure switches, respectively, high-voltage switch and low-voltage switch, double pressure switch is equal to the two pressure switch integrated a switch, the role of high-voltage switch is too high pressure disconnect circuit protection compressor and Air Conditioning System. The role of low-voltage switch is when the pressure is too low or when the lack of refrigerant circuit breaker to open the compressor; Double pressure switch in the four lines are two high-voltage switch line, the remaining two are low-voltage switch line, four lines are generally two colors; To determine the pressure switch failure first use the air conditioning pressure gauge to measure the system pressure, the general failure is the system pressure normal compressor does not work, first check the compressor insurance and pressure switch is not power, there may be some failure is too high or too low pressure Can not disconnect the circuit in time to play a protective function, this failure is unlikely.
