Importance of Sensor Stability in Clean Rooms

The purpose of a clean room is to limit the number of particulates in a clean space. These particulates can be any type of sub-micron particles, such as dust, pathogens, chemical vapors, or moisture droplets. Clean room manufacturing areas are used by many industries to produce semiconductors, pharmaceuticals, medical devices, etc.

Maintaining a proper differential pressure between the clean room and the exterior area is the most crucial aspect of keeping the clean room “clean”. To understand why sensor stability is important to these critical applications, it is important to also understand why a pressure difference is needed.  Continue reading “Importance of Sensor Stability in Clean Rooms”

What are Room Pressure and Room Status Monitors?

Differential pressure between two rooms prevents dust, particulates, and pathogens from entering or exiting one room and going into the other. Depending on the relationship between rooms, one room will be under positive pressure when referenced against the other. This positive-negative pressure relationship between two spaces is the main idea behind clean rooms and isolation rooms. To ensure the differential pressure relationship is maintained, a measuring device must be used.

Magnehelic® Gages Monitoring Isolation Room Pressure

Room pressure monitors and room status monitors measure, display, and transmit the differential pressure reading between two rooms. In general, room pressure monitors only monitor differential pressure. On the other hand, room status monitors monitor differential pressure and additional parameters such as relative humidity, temperature, air change, or door status. They are both used in critical applications that require critical low differential pressure relationships.  Continue reading “What are Room Pressure and Room Status Monitors?”

Importance of Sensor Stability in Educational Facilities

Educational facilities, or public and private institutions devoted to teaching students, differ in physical size and level of education programs. These institutions can range from preschool to university levels, all of which need proper heating, ventilation, and air conditioning (HVAC) systems and indoor air quality.

While indoor air quality (IAQ) is important for everyone’s health, it is especially important for young children that are still developing their lungs. The United States Environmental Protection Agency (EPA) Science Advisory Board has completed multiple school studies that show indoor air pollution among the top five environmental risks to public health.  Continue reading “Importance of Sensor Stability in Educational Facilities”

Importance of Sensor Stability in Healthcare Isolation Rooms

Magnehelic® Gages Monitoring Isolation Room Pressure

The purpose of a healthcare isolation room is to prevent patients with contagious illnesses from spreading to others or to keep immunocompromised patients safe from exposure to airborne pathogens. As such, there exist two types of isolation rooms, either positively or negatively pressurized. 

Positive pressure isolation rooms are designed to keep pathogens and outside air from entering the room, i.e. air inside the room is forced outward and is typically used for immunocompromised patients. Like clean rooms, it is important to maintain proper positive pressure within the protective isolation room to keep the patients safe.
