  LEFOO can design and manufacture all kinds of pressure, temperature, flow control switches, sensors, transmitters and other products according to the requirements of the application system operation.   As industry leading pressure transducer manufacturers, Lefoogroup will offer you high-quality pump pressure switch, a variety of pressure sensing products, different pressure transducers and transmitters that are compatible with a variety of liquids and gases.   Like ordinary products, the brand has a very large impact on the pressure transducer price. Generally, imported pressure sensors have a great advantage in the brand due to their strong pressure transducer manufacturers. The prices of imported brands of pressure transducers are generally higher, while domestically produced pressure sensors have a large advantage. The pressure transducers of Lefoo pressure control are more cost-effective than imported ones. LEFOO provide pressure differential monitor, peristaltic pu...

While LFM30 is only available for one type from 0~5V,0~10V, 20ma, or RS485.   The   differential...

  Pressure monitoring is the basic and most important measurement in oil&gas production. The process of oil transfer requires filling abundant water and sand into an underground oil layer to increase pressure while generates an extensive vacuum above the oil layer. The high-pressure side will force huge amounts of petroleum into the vacuum zero pressure side that can introduce the oil flow from even from the 10km depth underground.   However, the risk of burning and explosion of petroleum and natural gas is proportional to ambient pressure and temperature in the underground processing grounds. Even gasoline refined from petroleum is a flammable and explosive liquid in the transfer and transportation process. Hence the reliable and precise monitoring pressure transducer transmitter and gas pressure switch  control devices like pneumatic pressure switch are quite vital in the whole process of production, transportation, and selling.   Lefoo pressure transmitters an...

  The current HVAC system generally circulates the air to achieve the purpose of energy-saving, which will cause the indoor oxygen low concentration, and poor breathing may cause chest tightness, nausea and other symptoms.   LEFOO's carbon dioxide dp transmitter can monitor carbon dioxide in the air. Concentration, temperature and humidity transmitter can monitor the temperature and relative humidity in the air, temperature and humidity transmitter can also be used to monitor the storage conditions of medical equipment, T2000 can be used for medical gas leak alarm.   LEFOO differential pressure products like medical pressure sensors  can monitor the change of indoor air pressure and can be used to detect the gas pressure in the clean ward of the negative pressure ward. Some influenza viruses will be more active indoors with low relative humidity and high temperature, and the survival period will be longer.   LEFOO provide pressure differential monitor, different...

  (LF40H)Cut in and off Pressure: 1.5bar / 2.5bar (LF40L) Cut in and off Pressure: 0.1 / 0.2 bar Good working stability Excellent durability and pressure resistance Water supply pressure control for the water purifier   Water Pressure Switch LF42H Water Pressure Switch LF42L The automatic pump control switch for water pump  consists of a robust pom plastic casing, spring trigger, pom plastic transmission lever, micro-movement insert 4.8*0.8, material brass and tin-plated, silicone rubber sheet( thinnest position is 1mm height), and it is completely sealed by squeezing the rubber sheet. The action process of the device is like this. The diaphragm transmits pressure to the transmission lever, and the transmission lever triggers the action of the microswitch.   The LF42H (high-pressure protection) will off the electric water pump pressure switch when liquid pressure reaches the pre-set high-pressure threshold to prevent overflow of the water system. The LF42L(low-pressu...

  Digital water pressure sensor  are frequently used for inlet and outlet water pipe pressure measurement in clean water systems at public utilities.   WATER PRESSURE SENSOR AND WATER PIPE PRESSURE MEASUREMENT Water pressure sensors are frequently used for inlet and outlet water pipe pressure measurement in clean water systems at public utilities. Some water systems are fed by the gravity flow of the water, usually, lift stations pump the water to a higher elevation to provide reliable gravity flow. Water pressure in the pump well, water tower needs to be monitored by a water differential pressure sensor to control the predetermined water flow rate at the pump input, which turns off the pump at a minimum flow rate to prevent empty run damage. Also, pump well and water tower that undergoes a large release of water require water supplement.  Pressure sensors for water pumps offer reliable pressure measurement for the pump and the observer can determine when to adjust a...
