  A pressure switch is a control device that runs a switch on or switch-off action when a preset pressure value occurs. LEFOO pressure switch  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 switch control   is high accuracy with numerous pressure ranges, flexible for any connections.   Lefoo Low Pressure Switch HVAC, Lefoo High Pressure Switch HVAC A mechanical adjustable pressure switch applies a spring-tr...

  LEFOO LFT2800 pressure transmitter is widely used in the measurement of fluid medium pressure in test systems such as fire protection, water treatment, water supply systems, air compressors, pneumatic devices, and factory automation. This type of Oil-filled pressure transmitter has excellent anti-corrosion and anti-wear performance, adopts ASIC technology, MEMS technology, digital compensation, and can be used in various complex environments.   Features:   * Oil-filled silicon core with high overload capacity   * Excellent corrosion and wear resistance   * Using ASIC technology, digital compensation   * Can be used in a variety of complex environments   If you are looking for a reliable pressure transmitter manufacturer , please contact us.   We can also provide kinds of differential air pressure sensor   for sale, if you are interested, please contact us.  

  Consists of magnetic spiral movement and a rubber diaphragm as the sensitive element to measure the pressure. LEFOO pressure differential monitor  LFB-1 is a kind of elastic strain gauge that displays the pressures of tested gas by pointer and scale. The positive pressure type, negative pressure type, or differential pressure type are optional.   Specification of Differential Pressure Gauge LFB multiple ranges are optional, minimum 0 ~ 30Pa to maximum 0 ~ 210KPa   two sets of pressure ports (side, back) + 3 mounting modes = free and flexible application.   Excellent accuracy, reasonable price.   Environment temperature -70 ~ 60°C   Rated pressure -68 ~ 103KPa   DP gauge, Dwyer Magnehelic replace   The function of a differential pressure gauge   The media chambers of a differential pressure gauge are separated from each other by the pressure element. If the two pressure measurements are the same, there is no movement through the pressur...

  Peristaltic pump is a dosing pump designed based on the peristaltic principle. It is most suitable for precise transfer and control of liquids, solutions, pastes... Brief Introduction Of Lefoo Peristaltic Pump Peristaltic metering lab pumps are a type of liquid transfer pump used for pumping a variety of fluids such as oil, detergent, beverage, sauce chemical solution. Hence these pumps are also called the chemical dosing pump   As peristaltic pump manufacturers , LEFOO pressure control possesses scalable technology applied in peristaltic dosing hose pump to meet different process needs. Using our cheap peristaltic pump , the hose is the only part that needs to be replaced. Like our stepper motor peristaltic pump which is not only inexpensive but also quickly replaceable on site.   The cheap peristaltic pumps   is also known as a peristaltic hose pump or soft pipe pump, LEFOO peristaltic metering pumps are powered by a 24V DC motor or stepper motor, durable hose, r...
