Temperature plays a decisive role in modern building technology, industrial processes, and IT infrastructure. With the Wiesemann & Theis Web-Thermometer UV, a leading manufacturer of measurement and automation technology presents an innovative system for real-time temperature monitoring. This compact and highly efficient device was specifically developed for integration into sub-distributors, server rooms, and control centers. It combines precise sensor technology with the performance of modern IoT networks. Thanks to versatile communication protocols such as OPC UA, MQTT, and REST, the thermometer can be seamlessly integrated into existing building automation systems.

The Web-Thermometer UV measures temperatures in the range from –50 °C to +180 °C and, depending on the connected sensor, even up to +650 °C. This enormous range covers the requirements of industrial environments as well as precise climate monitoring in data centers or technical rooms. Using cloud-based temperature monitoring, users can access their data worldwide – whether at the workplace, in field service, or in the home office. Alarm messages are sent automatically via e-mail, push notification, or SNMP trap, so critical deviations are immediately reported. The precise measurement technology combined with a clear user interface makes the system a powerful tool for any temperature monitoring system.

The sub-distributor design allows space-saving mounting directly on the DIN rail. This allows the thermometer to be installed in electrical distribution systems, automation centers, or network cabinets without additional effort for wiring or configuration. The IoT temperature sensor operates with high resolution and stable signal processing. It delivers accurate values in real-time that can be evaluated via the web interface, via the local network, or via the cloud. The Web-Thermometer UV thus sets new standards in terms of reliability, flexibility, and user-friendliness.

Through its modular design, the measurement system fits perfectly into any digital infrastructure. Whether as a single temperature meter or as part of complex IoT monitoring solutions – the Web-Thermometer UV offers diverse application possibilities. Particularly in building automation, it helps optimize energy efficiency, control air conditioning systems according to demand, and reduce operating costs. With its robust construction, energy-efficient power supply, and five-year warranty claim, it is predestined for continuous operation. In this way, Wiesemann & Theis ensures that users receive precise, reliable, and secure temperature measurements at all times.

Technical Excellence and Practice-Oriented Design

The Wiesemann & Theis Web-Thermometer UV combines state-of-the-art measurement technology with a user-friendly design. All components were developed for durability and accuracy. The manufacturer's internal development guarantees high manufacturing quality and uncompromising precision. The device operates virtually maintenance-free and offers an intuitive user interface that allows configuration, monitoring, and evaluation to be carried out effortlessly. The underlying technology is designed to be understandable and clear for both IT managers and energy or building technicians.

A particular highlight is the integration into cloud environments. Via the secure connection, temperature curves can be stored, visualized, and evaluated long-term. Companies thus have the opportunity to document temperature histories, recognize trends, and activate early warning systems. In case of threshold violations, the temperature monitoring system automatically reports an alarm. This prevents expensive IT or production failures. The application diversity ranges from small technical rooms to large-scale energy management systems.
