Siemens Building Technology 547-104A Room Pressure Monitor

The Siemens Building Technology 547-104A Room Pressure Monitor is a sensing and display component that measures and conveys the air pressure difference in regulated spaces. With a range of ±0.50" water column measurements with 0.5 per cent full-scale accuracy and small P1 configuration, it then measures the difference between the spaces and transforms it into readable output signals. It is used in HVAC systems where pressurisation of the rooms is necessary. It facilitates the maintenance of an adequate airflow balance prevents contamination, and maintains stable conditions by constantly tracking changes in pressure.
