SmartDisk™ Relief Device Manager™ optimizes the ‘total cost of ownership’ of Pressure Relief Devices. The Relief Device Manager collects pressure & temperature data directly at the pressure relief device, analyzes the information for characteristics that can be detrimental to prolonged service life and provides the user with alarms and warnings when it is appropriate to take planned maintenance action, as well as giving an immediate indication when a Pressure Relief Device was activated.
What is the SmartDisk Relief Device Manager?
In its simplest form, Series 1 and Series 2, Relief Device Manager comprises a processor with integral LCD display located adjacent to the Pressure Relief Device in an appropriate enclosure. The processor display normally indicates the raw input signals from the attached sensors but immediately switches to display an alarm (rupture) or warning condition on its own LCD screen in standard text format. Alarm and Warning status can be externally communicated as well using separate relays integral to the processor. Each Relief Device Manager System is customized. This ensures sensitivity to the unique application conditions that are being monitored. The standard SmartDisk Relief Device Manager processor & sensors are approved for use in Intrinsically Safe applications when appropriate barriers are installed. The SmartDisk Relief Device Manager can be extended to multiple pressure relief devices.
SmartDisk Relief Device Manager – Series 1 Designed for:
Applications where a Pressure Relief Device vents to a stable downstream, normally atmospheric pressure condition. In this configuration, the measurement of pressure at the inlet side of a rupture disk informs Relief Device Manager of the differential pressure across the device.
Information Collected:
(Based upon a combination of two analog inputs and one digital input)
- Pressure conditions at the Rupture Disk Inlet
- Temperature conditions at the Rupture Disk Inlet
- Burst Alert Sensor status (disk burst/unburst)
Information Provided:
- Disk Operating Ratio Exceeded
- Disk Cycle Life Exceeded
- Disk Too Hot
- Disk Rating Heat Affected
- Disk Burst
SmartDisk Relief Device Manager – Series 2 Designed for:
Applications where a Relief Device Manager vents to a variable downstream pressure condition. In this configuration, the measurement of pressure on both sides of the Relief Device is required to inform the Relief Device Manager of the differential pressure across the device.
Information collected:
(Based upon a combination of three analog inputs and one digital input).
- Pressure conditions at the Rupture Disk Inlet
- Pressure conditions at the Rupture Disk Outlet
- Temperature conditions at the Rupture Disk Inlet
- Burst Alert Sensor status (disk burst/unburst)
Information Provided:
- Disk Operating Ratio Exceeded
- Disk Cycle Life Exceeded
- Disk Dynamic Cycle Life Exceeded
- Disk Too Hot
- Disk Rating Heat Affected
- Disk Vacuum Limit Exceeded
- Disk Back Pressure Exceeded
- Back Pressure Present
- Vessel MAWP Exceeded
- Disk Burst
SmartDisk Relief Device Manager PackageFor Series 1 and Series 2, this comprises:
- Processor with display
- Enclosure appropriate to local electrical requirements (mounting configuration to be advised to BS&B)
- Pressure sensor(s)
- Temperature sensor
Additional items required are:
- Burst Alert® Sensor
- Rupture Disk Safety Head with appropriate connections for pressure and temperature sensors (or equivalent close coupled installation)
- Power supply 12 or 24
- Wiring requirements need to be specified at time of order.
