Detailed Description
DESCRIPTION
LFM33 Diferential Pressure Transmiter/Controller adopts high-precision MEMS digital pressure sensor,which candetect positive pressure,negative pressure or differential pressure.It can choose analog signal 4~20mA&0~10V orRS485 signal output.It has optional relay switch control and can independently set the relay switch action pressurepoint.It supports a variety of working mode settings to match the actual application requirements.The internal buzzerand LED indication can achieve pressure alarm and indication.Pressure unit switching and digital damping flterdegree can be set on site.It's widely used in air or neutral gas detection and control,and suitable for gas pressuredetection of various ventilation and air conditioning systems and equipment,and differential pressure detection offilter resistance in clean studios laboratories,and gas pipelines.
