LFM55 Differential Pressure Transmitter is widely used in differential pressure detection of air or neutral gas. The product installation takes up small space, and can be embedded in system surface or installed inside switch box. The product panel is made of 316L stainless steel. The surface is smooth and dust-free and has strong corrosion resistance, which meets clean room standard. Customers can setup measurement range, communication address and other functions on site. The product has sound and light alarm function, and can set the alarm pressure point, alarm delay time, and alarm function on/off on site. The product adopts imported micro-pressure sensing element with temperature compensation, and has the characteristics of sensitive pressure response, long term output stability, and excellent temperature performance. The products can be widely used in clean rooms, operating rooms, dust-free laboratories, also suitable for HVAC, intelligent buildings and other applications.
