Product Description:

Performance Parameter

The pressure control of product consists of three parts: pressure gauge, photo-electric

sensor,electronic circuit. Pressure gauge is used for measuring pressure value,photo-electric

sensor is responsible for transmitting pressure start &stop signal to circuit board , then the circuit

board processes the signal of photo-electric sensor, to judge whether the controlled equipment is

closed or started. The control mode can be divided into two kinds: direct on/off control and signal


  The product control pressures by adjusting the red and green position indication, reference point

is not mechanical contact, but guarantee the stability and accuracy with Photo-electric principle.

In products such as ordinary pumps and air compressor, internal electronic circuit design can

directly control power which doesn’t exceed 2.2KW , without external control cabinet and

auxiliary relay.

Function of pessure controller for pumps  

This product is different from the conventional pressure switch:It’s combined electric contact pressure gauge combines the advantages of accurate readings, through photovoltaic technology control the installed equipments on-off freely. Product design components including: a stable and reliable electronic circuits , high-performance electronic relays, sensitive precise photoelectric sensor, electric contact pressure gauge plate, high-strength plastic sheet (or metal sheet).

To comparing with the traditional domestic and foreign products, we have the following advantages:

1, Arbitrarily set to start and turn off the value of stress value.

2, Precise control makes no problem in continued repetition on-off.

3, Working stress shows on dial makes observation more convenient .

4, Long working life, stable performance.

5, The minimum pressure can adjustable to zero pressure at start, control more convenient;

6, Free from pressure limited ,0-6KG / CM 2 ,0-10KG / CM 2 ,0-50KG / CM 2 ,0-500KG / CM 2, or higher;

7, Free from working condition limited, it can work in any places there is pressure.

8,Don’t need to install the pressure tank

You can enjoy more advantages in using our products.

Detailed introduction of solar energy & air source installation

1. If increasing the pressure with canned motor pump,then just have to install the automatic valve

2. If increasing the pressure with high-head self-priming pump and centrifugal pump, then must install the valve on the pump outlet,automatic switch should be installed on the pipeline which is behind the valve and away from the valve more than 1m ,so that the pressure switch can receive steady pressure and prevent the pressure gauge needle from shaking.


When supplying water from up to down,attention that the pressure should be less than 2kg. So it’s better to choose the pump with smaller pressure. If thepressure is too high, will make the switch frequently start, so that greatly reduce the service life of pressure switch, the service life of pumps and valves will also reduce.

3. Pressure switch selection, must according to the pump’s actual head to choose the pressure switch which is a little higher than the highest head of the pump.

Pressure switch adjusting mode:

After having installed the pump and pressure switch:firstly, set the upper limit of pressure switch to the highest, then start the pump and close all valves, check the value on the pressure gauge, if the pressure is higher than 2.5KG,set the upper limit around 2.5KG., if the pressure is lower than 2.5KG, upper limit setting must according to the actual water condition.

Adjusting mode:

Start the pump,adjust the upper limit of pressure switch to the highest, check the biggest value of pressure switch needle when the pump is working, then open the water valve which is on the highest floor, adjust the water consumption with the valve on the pump outlet, when the water consumption is suitable on the highest floor, keep the water consumption steady,watch the value of needle on the pressure switch, then set the upper limit value of pressure switch a litter higher than the value of this moment ,but lower than the value when the valve is closed, set lower limit to 0.3—0.4 KG..

Q:After the fire control room reset, the pressure switch of the regulatory alarm immediately appeared, how can not reset?
2, pressure switch problems, electrical contact Piece stick dead can not be reset, the pressure switch to the module line short circuit and so on.
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.
Q:Home booster pump pressure switch failure how maintenance
Flow switch failure. May be stuck by the garbage in the water. Remove the rinse. Or replace the water flow switch.
Q:What parameters are required for pressure switch selection?
Pressure switch selection required parameters: How much range is needed 2. Setpoint, upper limit alarm or lower limit alarm 3. Measure what media medium is in contact with the temperature
Q:How to connect the self-priming pump pressure switch
See you intend to put the pressure switch connected to the socket or in the middle of the pump line.
Q:Bora classic direction of the power pump pressure switch problem
Switch bad two times ah? I have a treasure to a classic, in July 2008 to buy, or I accompany him to buy it, the current driving more than 30,000 km, and you said that the pressure switch did not bad ah.
Q:Pressure switch on a pair of normally open point how to reach the alarm and direct Kai pump
B, when the double-contact pressure switch, the problem is simple, as long as a group of contacts wiring to the spray pump control cabinet, another group of contacts connected to the alarm host. Now the actual engineering applications, double contact pressure switch with more and more.
Q:What is the relationship between the pressure switch of the air conditioner and the blower resistance?
1, the pressure switch is to control the compressor and expansion valve and the pipeline between a pressure regulation.
Q:Pressure switch two sets of relay output and a single relay output What is the difference between it
Double relay output is the lower limit of the pressure and the upper limit of a relay were issued, that is, you can adjust and set the lower pressure and upper limit.
Q:Where the fire pressure switch is installed
The pressure switch is the main part of the fire sprinkler system and is installed in the wet alarm valve of the fire sprinkler system.
