LFM108 Differential Pressure Transmitter
PRODUCT FEATURES
Description
LFM108 differential pressure transmitter is used to detect differential pressure or gauge pressure,and convertthisdierential pressure into proportional signal output.It can output 0-5/10V,4-20mA or RS485 digitasignal.This product isused in building energy management system to measure the precise pressure and flowrequired for building pressurizationand air flow control.Also suitable for heating,ventilation and air conditioning(HVAC),energy management systems,VAVand fan control,environmental pollution control,static piping andclean room pressure fume hood control,ovenpressurization and furnace ventilation control.
