Pressure Monitoring

Apreco’s enhanced cleanroom DPMA system provides an effective means of monitoring and regularly recording the differential pressures held within the Clean area. The Differential Pressure Monitor/Alarm system logs data enabling investigation of alarm conditions if required.

The operator interface is kept as simple as possible to minimise staff involvement, thus allowing staff to concentrate on their work, whilst the DPMA system looks after the working environment.

Through the touch display screen or PC interface, each sensor channel can be set to alarm at a specific set point. To eliminate unwanted alarms, each channel can be set to specific delay periods to eliminate spurious alarms.

During alarm periods, the controller will retain the pressure values recorded in its memory. This data can be either read directly through the display screen or with a suitable interface on a PC.

The display screen gives quick visual indication as to which area is in an alarm condition. An optional audible warning siren and alarm beacon can be supported by the system.

When an alarm has been registered, it remains latched until the differential pressure has been restored in all areas where there has been an alarm condition and the alarm has been acknowledged. This ensures that alarm conditions do not occur anonymously.

The FMS software has been developed to enable 21 CFR part 11 compliance. FMS is assigned GAMP category 4 as configurable software. The software is designed to meet the regulatory requirements of MHRA, BSI ISO 9000, US FDA, EU Tissue & Cell Directives (HFEA regulated).
