About PCI Space Pressure Monitors
Positive and negative space pressurization is very important for the control of airborne pathogens and particulate contaminants. Positive space pressurization isolates people or processes in a space from exposure to contamination from outside sources. Negative pressurization contains the contamination to the controlled space thus protecting people or processes outside. In most instances these positive or negative conditions must be constantly maintained. PCI Space Pressure Monitors (SPM Series) are designed to monitor the pressure differential (positive or negative) between two rooms or spaces in a building and activate an alarm when the differential pressure deviates from the setpoint. PCI SPM Series sense true pressure to establish the differential, unlike systems that use thermal means or hot wires to measure air velocity through a "calibrated" passageway between the controlled and the reference spaces. Such systems only imply that a pressure differential exists. PCI SPM Series use the newest state-of-the-art industrial grade, high accuracy, ultra-low pressure sensing cells. This new sensor technology not only assures exceptional accuracy but long-term stability as well. PCI SPM Series are ultra-sensitive, stable and reliable, and are capable of measuring and alarming to within 0.5% of full scale and displaying the pressure to 0.0001 inches of water column (0.0249 Pascal). Therefore, the SPM Series can meet the most stringent requirements of hospital areas such as patient isolation rooms and operating rooms, as well as research facility laboratories, pharmaceutical sterile fill enclosures, semiconductor fabrication facilities and most cleanrooms. Each SPM consists of a controlled space sensor, a reference space sensor, and a space pressure monitor panel. The space sensors are designed to be installed in standard single gang electrical boxes usually placed in the room walls. The monitor panel is placed in the wall of either room in a triple gang double deep electrical box. Standard 0.25 inch control tubing is run within the wall from the sensors to the monitor panel.
