Brief Introduction of Lefoo Differential pressure transmitter 

Versatile LFM108 differential pressure transmitter ranges from 0~ +50 Pa to 0~ +10 KPa. And customized 34 kpa measuring span is available (HVAC compressor with differential pressure sensor HVAC, low-pressure end of gas energy industry ).

Digital differential pressure transmitter LFM31 with buttons and display is employed for measuring system air pressures, which is available for the user to select appropriate options when observes environmental air pressure changes, Versatile LFM32 Air pressure transmitters are available with the compound version of the outputs signal. While LFM30 is only available for one type from 0~5V,0~10V, 20ma, or RS485. 

The differential pressure transmitter uses the piezoresistive effect of the conductor silicon material of the differential pressure sensor/transducer to realize the conversion between the differential pressure and the electrical signal.

The low differential pressure transducer made by LEFOO pressure control is ideal for the application of monitoring the vacuum pressure, a gauge pressure of air with differential pressure, such as natural gas, and especially low pressure of non-corrosive gases.

DP 810 Differential pressure transmitter is capable of pressure measurement for media such as liquid, solution, oil, glue, chemicals, petroleum gas.

High exactness and long stability are vital for an energy-efficient, well-functioned air ventilation system. LEFOO comes in different models where the most advanced models help you save installation time and cabling through quick and easy assembly steps, which features as below:

1. One air differential pressure transmitter instead of two! Each transmitter holds two pressure inputs. High exactness measurement. High water-resistance functions. Lightning protection.

2. Easy installation, there is plenty of space in the cover and that it is easy to access the wiring.

Vertically or horizontally, No need to worry about placement or hassle during installation.  LEFOO differential pressure transmitters have mounts,  which gives you great flexibility.
