  A pressure switch is a pressure switch control     device that runs a switch on or  switch-off action when a preset pressure value occurs. LEFOO   low pressure switches and high pressure switches are mainly used as the flow controller for fluid or gas in applications such as HVAC systems, water pumps, boilers, gas tanks. The Lefoo group was launched in 2000, Lefoo manufacture pressure switches for an extensive range of industries include -10000 pa to 10000 pa, and from 0~200 bar. Such as HVAC,  refrigeration, air, compressor and pump pressure, automatic water pump, vacuum, steam, differential pressure, float, miniature and vacuum, high pressure, level, and digital switches and sensors to meet the utmost needs of industrial application and harsh environment. Each LEFOO pressure control switch is high accuracy with numerous pressure ranges, flexible for any connections.

  Pressure Type: Ceramic core/oil-filled silicon core Pressure Range: -100kPa~60MPa Output: 4~20ma/ 0.5~4.5V/ 0~10V Pressure Accuracy: 0.25%F.S. / 0.5% F.S.   Pressure Measurement Types and Applications     To accommodate many different applications, manufacturers make many different types of pressure transmitter   for pressure measurements. Examples of these include water pressure, air pressure, medical gas, oil pressure, temperature, gas pressure, fuel pressure, differential pressure, and vacuum pressure. Some of the uses of these devices are more obvious than others.   Pressure transducer Classified by the Substance They Measure   Water pressure transducer (naturally) monitors the pressure of any water-based system. Quite commonly, they are found attached to tanks, where they monitor the pressure of the water within.   Gas pressure transmitter measures and displays gas pressure. They are especially prevalent in factories and manufacturing facil...

  Diaphragm Pressure Transmitter Pressure Type: Guage/ Absolute Diffusion silicon core + 316L thin diaphragm Pressure Accuracy ： 0.25%FSO / 0.5% FSO Electrical Connection: Parkard / Big Hessman / M12   Excellent silicon wafer, Wheatstone-bridge and pressure-sensitive diaphragm are sealed in a steel house filled with glycerine or silicone to encase the interior components of the sensor. diaphragm sensors are very sensitive to rapid pressure changes. -- they are commonly used in very corrosive environments or with extreme over-pressure situations.   Lefoo Sensor Selection Criteria, A good flat pressure sensor   should have the pros under below 1.
