In modern building automation and networked infrastructure, precise monitoring of ambient temperatures is essential, whether in server rooms, network cabinets, or industrial environments. The Web Thermometer UV from Wiesemann & Theis is a highly advanced measuring device specifically developed for integration into sub-distribution systems.

With its compact design, powerful Pt100 sensor, and extensive network capabilities, it offers a reliable solution for temperature measurement and logging. This article highlights the technical features, versatile applications, and advantages of this innovative device, which integrates seamlessly into building automation systems and takes temperature monitoring to a new level.

Precise Temperature Measurement with Pt100 Sensor

The Web Thermometer UV is equipped with a high-quality Pt100 temperature sensor that measures temperatures in the range of -50 °C to +180 °C. The device's measuring input supports an extended range of -200 °C to +650 °C, making it suitable for demanding applications in industry and IT. Pt100 sensors offer high accuracy and stability, making them ideal for environments where precise temperature data is crucial. The special sub-distribution design allows for easy integration into existing systems, simplifying installation and expansion of building automation systems. This precision is essential to prevent equipment damage, increase energy efficiency, and reduce operating costs.

Intuitive Operation and Network Connectivity

The Web Thermometer UV is extremely user-friendly thanks to its intuitive web interface. Without additional software, users can access real-time temperature data, analyze trends, and adjust settings via a web browser. The graphical display of temperature trends makes it easier to detect patterns and potential issues, making monitoring more efficient. This user-friendly interface allows for quick commissioning and adaptation to individual requirements, making the device ideal for both experienced technicians and beginners. The compact sub-distribution design also allows for space-saving installation, which is especially beneficial in tight network cabinets or sub-distributions.

Flexible Alarm and Reporting Functions

The Web Thermometer UV offers comprehensive alarm and reporting capabilities. Up to 12 individually configurable alarms can be set up, which automatically send notifications when defined temperature limits are exceeded. These alarms can be sent via email, SNMP trap, or Syslog, which is particularly useful in critical environments such as server rooms, where rapid responses to temperature fluctuations are required. Additionally, the reporting function allows for regular sending of temperature summaries via email. These reports are ideal for audits, energy analyses, or documentation of operating conditions and enhance transparency in monitoring. Support for advanced security requirements also ensures that sensitive data remains protected.

Seamless Integration into Industry 4.0 and Building Automation

The Web Thermometer UV is fully equipped to meet the requirements of Industry 4.0 and building automation. It supports modern protocols such as OPC UA, REST, and MQTT, allowing for simple integration into existing automation systems. Furthermore, it offers interfaces like SNMPv1, SNMPv2c, SNMPv3, Modbus-TCP, OPC DA, and Sensobase for database integration via ODBC. Developers can access the measurement data directly via TCP or UDP sockets to develop custom solutions. The HTTP interface allows direct access to current measured values, for example via JavaScript (AJAX), to dynamically integrate them into other websites or applications. This extensive connectivity makes the device an indispensable tool for networked environments and building automation.

Long-Term Data Storage and Global Access

An integrated data logger stores temperature data for a minimum of 16 weeks and up to 20 years, depending on the selected storage interval (15 seconds to 1 hour). The data can be exported in various formats such as FTP, Excel files, or email attachments, allowing for flexible further processing. Integration with the W&T Cloud enables worldwide access to stored measurement data, allowing access anytime and anywhere. An internal battery-buffered clock provides precise timestamps, which can be further refined by synchronizing with a time server. These features ensure reliable documentation and analysis of temperature trends, which is particularly beneficial in building automation.

Versatile Areas of Application

The Web Thermometer UV is designed for a wide range of applications. In server rooms and network cabinets, it monitors the ambient temperature to prevent overheating and extend hardware lifespan. In office environments, it supports optimization of air conditioning systems, increasing comfort and reducing energy costs. In industrial environments, the device is suitable for monitoring processes where precise temperature control is critical. In the context of Green IT, the Web Thermometer helps increase the efficiency of cooling systems in server rooms by providing accurate data for cooling optimization. The sub-distribution form factor makes it particularly suitable for expanding building automation systems, as it integrates seamlessly into existing infrastructures.

Flexible Power Supply and Standards Compliance

The Web Thermometer is powered via Power-over-Ethernet (PoE), supporting both phantom power over data pairs and power over unused wire pairs. Alternatively, an external power supply can be used, expanding deployment options in environments without PoE infrastructure. The device is standards-compliant for use in office and industrial environments, offering high immunity to interference according to EN 61000-6-2 and low emission levels according to EN 55032:2015 + A1 Class B, EN 61000-3-2, and EN 61000-3-3. These features ensure reliable and uninterrupted operation, even in demanding environments.

Please note: No power supply is included in the scope of delivery.

Durability and Reliability

The Web Thermometer UV is designed for continuous operation and comes with a five-year warranty. The robust construction and special sub-distribution form factor make it ideal for use in industrial environments and building automation systems. The internal clock, buffered by a battery, ensures precise timekeeping, which is optimized by synchronization with a time server. These features emphasize the device's durability and reliability, even under demanding conditions.

An Indispensable Tool for Temperature Monitoring

The Web Thermometer UV from Wiesemann & Theis is a state-of-the-art solution for precise temperature monitoring in a wide range of scenarios. With its Pt100 sensor, integrated data logger, and extensive network capabilities, it provides a flexible and reliable solution for server rooms, offices, and industrial applications. The sub-distribution form factor allows easy integration into building automation systems, while support for modern protocols such as OPC UA, REST, and MQTT, along with cloud connectivity via the W&T Cloud, make it ideal for the demands of Industry 4.0.
