Rooster™ Pressure100 Monitor/Alarm

There are clean manufacturing and healthcare applications where it is essential to maintain a pressure difference between adjacent rooms. Positive pressure rooms are kept at a higher pressure than external surrounding spaces to keep contaminants from entering the protected area. Conversely, negative pressure rooms are kept at a lower pressure than the external environment to keep contaminants from leaving the contained space. The Rooster™ Pressure100 with color touch panel display from Degree Controls monitors differential pressure between two rooms, providing visual and audible alerts, digital alarm communication, and full-screen colorization to indicate room status. In addition, Pressure100 tracks humidity and temperature in real time and is easily installed to establish an effective containment solution for isolation rooms, hospital negative pressure rooms, clean rooms, and other controlled spaces. It is a logical choice for upgrading outdated “ball-in-wall” devices and magnehelic gauges.

The Rooster™ Pressure100 measures differential pressure by means of flow-through technology. The sensor element covers a pressure range of up to ±125 Pa (±0.5 inch H2O) and is calibrated, temperature compensated, and compatible with air and inert gases. Pressure100 detects changes in room pressure which could affect safety and product quality. By continuously monitoring airflow, Pressure100 also helps organizations meet compliance requirements, such as those applicable to pharmaceutical manufacturers. Users can assess their environments and generate support documentation for records and compliance reports with Pressure100’s data and event logging capabilities.

Typically, the Rooster™ Pressure100 display module is mounted near an access door, in the controlled room, with the pressure sensor mounted above it. Door switches can be wired into a binary input to detect when door(s) are open, and a dry contact occupied status input permits remote changing of pressurization alarm setpoints to “unoccupied” levels. Pressure100’s advanced feature set also includes two levels of password protection, configurable alarm behavior, and in-the-field firmware updates. 

Rooster™ Pressure100 is intuitive, easy to use, and provides the best value for pressure monitoring in critical environments. Some hospital clients have even expanded Pressure100 installations to areas which are not subject to compliance agencies, to give staff, patients, and visitors peace of mind.

ANSI/ASHRAE/ASHE Standard 170, Ventilation of Health Care Facilities defines pressure relationships, room air exchange rates, and humidity and temperature ranges for hospital spaces.
