LFM108 differential pressure transmitter is used to detect differential pressure or gauge pressure, and convert this differential pressure into proportional signal output. It can output 0~5/10VDC, 4~20mA or RS485 digital signal. This product is used in building energy management system to measure the precise pressure and flow required for building pressurization and air flow control. Also suitable for heating, ventilation and air conditioning (HVAC), energy management systems, VAV and fan control, environmental pollution control, static piping and clean room pressure, fume hood control, oven pressurization and furnace ventilation control.
Adopt high-precision MEMS sensor, wide temperature compensation, sensitive pressure response.
Set the zero calibration button to save installation time and facilitate later maintenance.
Strong stability and long service life.
Compact size for easy installation.
