Lefoo Embedded Differential Pressure Transmitter LFM55

LFM55 embedded differential pressure transmitter is widely used for differential pressure detection of air or neutral gas. Users can customize the range, set the communication address and other functions according to the site; it has sound and light alarm function, and can set the alarm pressure point, alarm delay time, and alarm function on/off on site. It adopts imported micro-pressure core, with built-in temperature compensation, and has the characteristics of sensitive pressure response, long-term stable output, and excellent temperature performance. The panel is made of 316L stainless steel material, with a smooth surface without dust accumulation and strong corrosion resistance, which meets the clean room standards. It can be widely used in clean rooms, operating rooms, dust-free test rooms, and is also suitable for heating, ventilation and air conditioning (HVAC), smart buildings and other applications.
