The DPT55 embedded differential pressure transmitter is designed for precise differential pressure detection of air or neutral gases, offering a compact structure that allows for surface embedding or installation within switch boxes. Its 316L stainless steel panel features a smooth,dust-free, and corrosion-resistant finish that meets clean room standards. Users can easily configure measurement range, communication address, and other parameters directly on site.Equipped with sound and light alarm functions, the DPT55 allows on-site adjustment of alarm pressure points, delay times, and activation settings. Utilizing an imported micro-pressure sensing element with temperature compensation, it ensures high sensitivity, long-term output stability, and excellent temperature performance. The DPT55 is ideal for clean rooms, operating rooms, and dust-free laboratories, as well as HVAC systems, intelligent buildings, and similar applications.
