547-311A | Siemens | Pressure

The 547-311A is a Siemens integrity of a ventilation control system, the heart of a contaminant-free environment. Whether a room is at a negative pressure to prevent contaminants from escaping or a positive pressure to prevent contaminants from entering, the proper pressurization of a room is essential. To assure proper pressurization, a Siemens Room Condition Monitor (RCM) monitors pressure changes by measuring and displaying low differential pressures.
