Fb30 pressure switches are used to regulate tank pressure between two preset values on small (up to 175psi) electrically driven air compressors. Equipped with an unloader valve, they could prevent compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor. Both one and four-ports manifold style are available which provides easy mounting of valves and gauges.. 1) operating pressure range: 5bar-12 bar; 2) differential pressure range: 2bar 3) 20a, 240vac, 50hz 0.3kg, cartons

It can be used in plumbing system when it is necessary to make sure the pressure difference between two points does not exceed or drop below a specific value. The setting value can not be changed, which can ensure the flow setting value can not be changed. Features: Easy to install Good stability Adjustable ranges Accurately control flow No resistance effect on water system OEM capabilities include external adjustment knob with or without reference scale Monitoring and application: The pressure difference will increase with filtering, switch is on and output a signal when reached the pre-pressure value. If it automatically clean, the signal would be transmitted to controlling disk and then the controlling disk start to clean and open the waste valve. If worker to clean, the warning signal will be supplied. Pump status and feed back to automatic controlling system: The pressure difference is stable when the flow is constant, it would be changed when the system resistance is changed. The relation of pressure difference and flow, can refers to the pump performance data. So the differential pressure flow switch used for pump monitoring as well as the minimum flow control. When the actual pressure exceeds the set value, the switch output a dry contact signal for controlling system to indicate the pump has flow. The status light will indicates the pump status if it has. Heat exchanger flow controlling The differential pressure flow switch used for flow controlling is one of the most important application in HVAC system. It is the best substitutes of target type differential pressure flow switch. The reset flow is the minimum value used to check whether satisfy the requirement or not. The disconnect flow is protected instrument from decreasing flow. Following we take plate and extension-type heat exchanger and shell and tube type heat exchanger examples to introduce the characteristics of differential pressure flow switch. Plate and extension-type heat exchanger Plate heat exchanger with compact size and high heat transmission performance, has been widely used in cooling as evaporator and condenser. It is necessary to prevent plate heat exchanger from frost damage. A great deal of experimentation show that there is a possibility of freezing when the current flow less than the rated flow about 50%, so it is important to keep the current flow not less than 50% of rated flow. The pressure of 50% rated flow is the protection value of plate type heat exchanger, according to this value to choose differential pressure flow switch. We suggested to buy the fixed set point switch to ensure the value is right(the pressure difference can be tested by our professionals) Shell and tube type heat exchanger Shell and tube type heat exchanger used in cooling as evaporator and condenser. The unstable flow directly influence the mainframe., so it is important to control the flow to ensure mainframe work normally. The 70% pressure of rated flow is the lower limit of protection value, we can obtain it according to the pressure and flow curve or measure in scene. You can consult the professionals of the ACOL for specific method. We suggest to buy double set points adjustable differential pressure flow switch, one of them can be used to indicate the heat exchanger cleaning status. Set the reasonable pressure difference and choose the status light, when the waste is overmuch the status light is on to remind the customer to clean heat exchanger. Avoid energy waste because of the heat transfer effect drops and influence main engine work.

What is interactive whiteboard? An interactive whiteboard (iwb), is a large interactive display that connects to a computer and projector. A projector projects the computer's desktop onto the board's surface where users control the computer using a pen, finger or other device. The board is typically mounted to a wall or floor stand. What is interactive whiteboard used for? They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios and more. The interactive whiteboard industry has reached sales of us$1 billion worldwide by 2008; one of every seven classrooms in the world will feature an interactive whiteboard by 2011 according to market research by future source consulting. 186x165x12cm 58kg
