Continuous Monitoring System

Vaisala’s continuous monitoring system is a total solution — with data loggers, software, service and IQOQ validation. The system provides a user-friendly interface and accurate data loggers. Designed for regulated and critical environments, the system can be customized for enterprise-wide operations.

Key Benefits

Compliant w​ith major regulatory regimes
The system ensures data integrity with an audit trail, access controls, encryption, and authority levels that fulfill regulatory requirements. Compliance is simplified with validatable software, mapping/qualification capabilities, encrypted data and audit trail, optional, protocols and GxP documentation, ICH-compliant calibration options. Reports comply with GxP guidelines and standards, as well as FDA 21 CFR Part 11, EU Annex 11, ICH​​, etc.
Industry-best sensors, proven performance
Choose from a wide selection of transmitters, data loggers and probes. Options include wall, duct, and remote probe mounting capabilities. Temperature measurements range from -196 °C … + 1000 °C and humidity measurements to 100%RH. Measurements are traceable to SI units through national metrology institutes.
Operates independently, scales easily
For quick, simple validation, the system operates independently of other control and monitoring systems. Scale up easily—from one or two measurement points to thousands. With eight language versions the software is ideal for multi-site use and global monitoring. The system can manage multiple time zones and report in the local time.
Fully configurable
With a variety of alarm notifica​tion options and reports, the system is fully configurable to meet your needs. Data is logged continuously and autonomously at the point of measurement ensuring it is never lost to power or network downtime. Devices are easy to network through any combination of connectivity options, including Ethernet, PoE, or Wi-Fi.
Fully supported
Service options comprise full life cycle support, including installation, validation, and calibration-- either on-site or in our accredited calibration laboratories. Select a support plan that maximizes your system’s availability, lifespan, and performance. Support includes 24/7 access to multiple options: eLearning, user guides, online, and phone.
Designed for usability
viewLinc's software interface has been optimized for ease of installation and use. Reporting options include preconfigured reports that are easy to customize and can be delivered automatically or on user-selected schedules.

viewLinc Software
The Vaisala continuous monitoring system features the viewLinc Enterprise Server software and monitoring devices. The system provides alarming, real-time trends, and configurable reporting. Ideal for both light and heavy industrial environments, as well as GxP-regulated applications, the system integrates a wide selection of data loggers, transmitters and connectivity options to monitor temperature, relative humidity, dew point temperature, CO2, differential pressure, door switches, and more. The viewLinc software is backward compatible and able to use data created with older versions of viewLinc. All Vaisala DL-series data loggers are backward compatible with all versions of the viewLinc software.
Data Loggers
Monitoring system data loggers include several probe and mounting options and offer flexible wired or wireless connectivity, including Wi-Fi and PoE. Measurements are traceable to SI units through national metrology institutes or ISO/IEC 17025 accredited calibration laboratories. Measurement ranges: Temperature measurements from -196 °C to +1000 °C; humidity measurements to 100%RH. Dew point measurements from vacuum to 100 bars; ambient to -80 °C dew point. CO2 measurement from 0 to 20% for demand controlled ventilation and safety applications. There are intrinsically safe devices for hazardous/explosive areas. Vaisala's OPC Server software can also be used to integrate the DL-series data loggers with non-Vaisala systems.
Services and documentation
Vaisala’s team of engineers, metrologists and technical support experts are committed to ensuring that your continuous monitoring system functions flawlessly for many years. The system comes with a full suite of service options; from calibration services — onsite or in one of our accredited calibration laboratories — to installation, validation services, and support plans. We offer comprehensive documents, including IQOQ protocols and a GAMP-based GxP documentation package.
