Products Description
DESCRIPTION
LFM108 differential pressure transmiter is used to detect diferential pressure or gauge pressure,and converthisdiferential 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.
