A room pressure monitor is a device that monitors and measures the pressure of a given space in reference to another space. This value is called "differential pressure."

Room pressure monitors are used in "critical spaces" where contamination must be avoided. Critical spaces include hospital rooms, isolation rooms, operating rooms, cleanrooms, pharmaceutical manufacturing areas, vivariums, and data centers.

Some critical spaces such as data centers require monitoring more than just pressure to keep equipment running at peak performance. Pharmaceutical plants and other involved manufacturing facilities typically need to control the humidity, temperature, and particle counts of their spaces. Finally, a growing body of research is showing that hospitals can reduce infections by monitoring additional room parameters beyond just differential pressure.

Founded in 1967, Setra Systems, Inc. is a leading designer and manufacturer of pressure, acceleration, and weight sensing devices. Setra has devoted its engineering and research efforts to the development of transducers and systems based on the highly accurate variable capacitive transduction principle. Setra’s founders, Dr. Y.T. Li and Dr. S.Y. Lee, are Professors Emeritus of Engineering at MIT and the co–developers of the variable capacitance transduction principle, the innovative force sensing technology which is the heart of Setra’s products. Setra is ANSI–ASQ History Image ISO 9001:2008 certified through our registrar, National Quality Assurance (NQA). This prestigious certification requires Setra to maintain a documented quality system to ensure customer satisfaction through controlled design, manufacturing, and employee training programs. Setra Technology Park owned by Setra Systems, Inc., is located on a scenic 23 acre site in Boxborough, Massachusetts. Setra’s building is approximately 100,000 square feet and houses the executive offices, sales offices, and manufacturing facilities. In addition, Setra has additional manufacturing capacity in China at our wholly owned subsidiary, Danaher Sensors and Controls.
