The Model 261C series micro differential pressure sensor is specifically designed for HVAC applications. It adopts Setra's unique variable capacitance technology, which consists of a stainless steel mold and a gold-plated ceramic fixed electrode to form a variable capacitance. When the pressure changes, the gap between the two plates changes, causing a change in capacitance value. Setra's unique detection circuit converts changes in capacitance values into linear DC electrical signals.

The Model 261C series inherits Setra's traditional features of high precision, fast response, and ultra-low range. At the same time, considering the requirements of pharmaceutical factories and clean rooms for micro differential pressure transmitters, on-site LCD display has been added near the dust-free surface, fully meeting the requirements of industry applications. It is an ideal choice for pharmaceutical factories, electronic clean rooms, and dust-free laboratories.

The Model 261 is widely used in pharmaceutical workshops, clean electronic factories, and infectious disease wards due to its excellent performance price ratio.
