Seacom Process Instruments supplies, installs and supports the Vaisala viewLinc Continuous Monitoring System in Malaysia for pharmaceutical facilities, cleanrooms, laboratories, hospitals, warehouses, cold-chain storage, semiconductor manufacturing and other critical environments.
viewLinc brings measurement devices, secure records, real-time trends, alarm management, audit trails and reports into one scalable environmental monitoring system. It can monitor temperature, relative humidity, carbon dioxide, differential pressure, dew point, door contacts and other parameters through suitable data loggers, probes, transmitters and input devices.
| System layer | Function | Typical components |
|---|---|---|
| Measurement | Senses conditions at each room, chamber, refrigerator, freezer or process location | Temperature, humidity, CO2, differential-pressure and other probes or transmitters |
| Local recording | Stores timestamped measurements at the monitoring point during normal operation and temporary communication interruptions | Vaisala VDL200 or Vaisala RFL100 |
| Communication | Transfers recorded measurements to the monitoring server | Ethernet and Power over Ethernet, or VaiNet wireless through the AP10 Access Point |
| Monitoring software | Provides real-time views, alarms, trends, reports, audit trails and user administration | Vaisala viewLinc Enterprise Server |
| Notification | Escalates threshold, device and communication alarms to responsible personnel | Email, SMS or voice services, browser notifications, signal towers and compatible relay devices |
A monitoring system is not a control system: viewLinc records environmental conditions and alerts personnel when limits are exceeded. Critical control, shutdown and immediate life-safety functions should remain within appropriately engineered control and safety systems.
| Monitoring requirement | Recommended direction | Why it fits |
|---|---|---|
| Wireless room temperature and humidity | RFL100 with AP10 | Long-range VaiNet wireless communication with battery-powered data loggers and local memory |
| Wired temperature or humidity point | VDL200 with a compatible probe | Power and data through Ethernet, onboard memory and replaceable smart probes |
| Refrigerator or cold-room temperature | VDL200 or RFL100 with an external temperature probe | Keeps the logger accessible while the probe measures inside the equipment |
| Ultra-low freezer or liquid-nitrogen storage | VDL200 with TMP115 or RFL100 with TMP115 | Supports wide-range temperature measurement down to cryogenic conditions |
| CO2 incubator | VDL200 or RFL100 with GMP251 and the required temperature/humidity arrangement | Combines percentage-level CO2 with the required chamber measurements |
| Cleanroom differential pressure | CAB100 with suitable differential-pressure transmitters | Centralises transmitters, power supplies and interface components in a serviceable cabinet |
| Analogue transmitter or door contact | VDL200 with ANP115 or a CAB100 input configuration | Brings current, voltage or Boolean signals into the viewLinc system |
| Existing DL-series installation | Review the installed logger, probe and interface before expansion | Maintains compatibility while planning migration to current VDL200 architecture where appropriate |
| Mixed wired and wireless facility | VDL200 plus RFL100/AP10 on one viewLinc server | Allows each monitoring point to use the connectivity best suited to its location |

| RFL100 | VaiNet wireless | Battery-powered temperature, humidity and CO2 monitoring | Warehouses, laboratories, cleanrooms and locations where new cabling is difficult |
| AP10 Access Point | VaiNet to Ethernet | Connects RFL100 data loggers to the facility network and viewLinc server | Wireless systems; one AP10 supports up to 32 RFL100 data loggers |
| CAB100 | Ethernet with wired field inputs | Centralised integration of differential pressure, analogue signals and selected hazardous-area interfaces | Cleanrooms, pressure cascades and instrument-dense installations |
| viewLinc Enterprise Server | On-premises or virtual server | Monitoring, alarming, reporting, audit trail and user management | GxP-regulated and critical multi-point or multi-site monitoring |
| Parameter | Typical locations | Important selection detail |
|---|---|---|
| Temperature | Rooms, refrigerators, freezers, cold rooms, incubators and cryogenic storage | Define the full temperature range, probe position, cable routing and required accuracy |
| Relative humidity | Warehouses, cleanrooms, laboratories and controlled production | Consider condensation, chemical exposure and calibration access |
| Carbon dioxide | Incubators, laboratories and controlled environments | Select the correct concentration range and provide suitable power and probe installation |
| Differential pressure | Cleanrooms, isolation rooms, laboratories and air-handling systems | Confirm direction, range, room-pressure cascade, tubing and zero-check requirements |
| Door status | Cold rooms, refrigerators, freezers and secure storage | Define normally open or closed operation and the required alarm delay |
| Analogue process value | Particles, flow, level, pressure and third-party transmitters | Confirm signal type, scaling, power supply, isolation and engineering units |
| Modbus measurement | Compatible Vaisala and third-party instruments | Review register mapping, licensing, network architecture and supported device configuration |
When correctly specified, configured, controlled and validated, viewLinc can support monitoring requirements associated with GxP, FDA 21 CFR Part 11, EU GMP Annex 11 and data-integrity practices. The complete implementation—not the product name alone—determines whether the system meets the facility's intended use and quality requirements.
Compliance depends on implementation: user requirements, risk assessment, system configuration, calibration, validation, procedures, training, security, backup and change control must all be addressed. A statement that software “supports 21 CFR Part 11” is not a substitute for a validated system and controlled operational process.
| Alarm element | Question to define | Why it matters |
|---|---|---|
| Threshold | What limits protect the product, process or room? | Alarm limits should be justified rather than copied automatically from operating targets |
| Delay | How long may a brief excursion continue before notification? | Appropriate delays reduce nuisance alarms without hiding meaningful events |
| Recipient | Who responds during working hours, nights, weekends and holidays? | Every alarm path needs an available, trained owner |
| Escalation | Who is contacted when the first recipient does not acknowledge? | Prevents an active alarm from remaining unattended |
| Response | What action must the recipient take? | Notification is useful only when linked to a documented response procedure |
| Review | How are excursions, acknowledgements and recurring alarms assessed? | Supports investigation, corrective action and continual improvement |
DL-series loggers remain installed in many operational viewLinc systems. If an existing site uses DL1000, DL1400, DL1700, DL2000 or DL4000 devices, expansion and replacement should be reviewed against the installed probes, interfaces, software version and validation status.
| Existing requirement | Legacy equipment | Current planning direction |
|---|---|---|
| Temperature channels | DL1016, DL1416, DL1000 and DL1400 | Consider VDL200 for new systems; verify probe and installation requirements before migration |
| Temperature and humidity | DL2000 | Consider VDL200 with a compatible humidity and temperature probe |
| Thermocouple inputs | DL1700 | Review channel count, thermocouple type and current supported architecture before replacement |
| Universal analogue inputs | DL4000 | Consider VDL200 with ANP115 or an appropriate CAB100 input arrangement |
| Legacy Wi-Fi monitoring | HMT140 | Use RFL100 with AP10 for current wireless projects after a coverage assessment |
A migration should not be treated as a simple model-number substitution. Confirm sensor placement, measurement range, accuracy, wiring, network ports, alarm logic, historical records, calibration process and validation impact before changing an operational monitoring point.
Seacom Process Instruments can support a viewLinc project from initial monitoring-point review through system design, wireless assessment, network coordination, installation, commissioning, alarm configuration, calibration planning and GxP validation documentation.
