Vaisala viewLinc provides continuous monitoring, alarming and reporting for temperature, humidity, CO₂, differential pressure and other critical parameters in GxP-regulated and demanding industrial environments.
The Vaisala viewLinc Continuous Monitoring System is a complete environmental monitoring, alarming and reporting platform for pharmaceutical facilities, biotechnology production, cleanrooms, laboratories, warehouses, hospitals, blood banks, cold rooms, freezers and other critical environments.
At the centre of the system is viewLinc Enterprise Server 5.2, the current on-premises software platform. It receives measurements from Vaisala data loggers, transmitters and compatible Modbus devices, then provides real-time displays, multi-stage alarms, secure records, audit trails and automated reports.
viewLinc operates independently from process-control and building-management systems, preserving a separate monitoring record for quality and compliance. Validated data can also be made available to authorised external systems through optional OPC UA or the viewLinc API.
| System Layer | Function |
|---|---|
| Measurement Probes and Transmitters | Measure temperature, relative humidity, CO₂, differential pressure, dew point and other required parameters |
| Data Loggers | Record measurements independently and transfer data through Ethernet, PoE, Wi-Fi or VaiNet |
| Network and Access Devices | Provide secure communication between field devices and the monitoring server |
| viewLinc Enterprise Server | Stores records and manages monitored locations, alarms, events, reports and user access |
| Users and Alarm Recipients | Review dashboards and reports, acknowledge alarms and perform authorised system functions |
| External Systems | Receive authorised viewLinc data through optional OPC UA or API integration |
viewLinc is designed for regulated environments where monitoring records must remain complete, attributable, reviewable and protected from unauthorised change.

| EU GMP Annex 11 | Validation documentation, security, audit trails, data retention and controlled access support regulated computerised systems |
| Data Integrity | Secure records, device memory, audit trails and role-based permissions help protect measurement history |
| Calibration Traceability | Compatible devices are available with calibration traceable to SI units through national metrology institutes or accredited laboratories |
| Validation | IQ/OQ protocols and optional GAMP-based GxP documentation support documented system implementation |
| Audit Readiness | Historical, alarm, event and audit-trail reports provide accessible evidence for quality review and inspections |
| Alarm Method | Typical Use |
|---|---|
| On-Screen Alarm | Immediate notification for users viewing the system |
| Detailed alarm information delivered to selected recipients | |
| SMS or Voice | Escalation to mobile or telephone recipients using configured services |
| Signal Tower | Visible and audible local indication in production, laboratory or warehouse areas |
| Relay Output | Activation of compatible beacons, diallers or external alarm systems |
| Escalation Schedule | Progressive notification when an alarm remains unacknowledged |
The Vaisala VDL200 is the current secure PoE data logger for temperature, humidity, CO₂, analog and Boolean monitoring. Probe combinations support rooms, refrigerators, freezers, incubators and other critical equipment.
The established Vaisala DL Series remains an important part of many viewLinc installations. These compact loggers provide autonomous recording at the measurement point and are available for temperature, humidity, thermocouple and universal-input applications.
DL Series devices are particularly relevant when expanding an existing viewLinc system, maintaining compatibility with an installed logger fleet or addressing a specialised measurement that requires a dedicated logger type.
Vaisala DL2000
Temperature and relative-humidity data logger for rooms, warehouses, laboratories, stability areas and controlled storage environments.
Vaisala DL1000 and DL1400 Series
High-accuracy temperature data loggers for refrigerators, freezers, cold rooms, incubators, chambers and other critical equipment.
Vaisala DL1700
Multi-channel thermocouple logger for wide-range temperature monitoring, validation, mapping and specialised process applications.
Vaisala DL4000
Universal-input logger for integrating compatible current or voltage transmitters and additional measurement parameters into viewLinc.
