The precise measurement and monitoring of temperature values are of crucial importance in modern industry, building technology, and IT infrastructure. With the Wiesemann & Theis Web-Thermometer 8x, a leading German manufacturer presents a powerful temperature monitoring system developed specifically for complex environments and multi-point measurements. This solution combines advanced sensor technology, web-based visualization, and real-time data transmission in a single compact IoT system. By operating up to eight temperature sensors simultaneously, even large facilities, server rooms, or technical networks can be efficiently and reliably monitored.

The system uses state-of-the-art IoT temperature sensors with support for Pt100 and Pt1000 to cover a wide range of applications. The device measures values from -50 °C to +180 °C and, with optional expansion, even up to +650 °C. This flexibility enables precise monitoring in both standardized building structures and industrial high-temperature processes. With its stable and corrosion-resistant housing, the Web-Thermometer 8x is designed for long-term continuous use and provides consistent measurement results for many years.

For modern infrastructure, access to data from anywhere is crucial. Cloud-based temperature monitoring allows global data insight and centralized process control. Once a temperature alarm is triggered, a notification is automatically sent via e-mail, SNMP trap, or Syslog. Companies benefit from full transparency in their operations—whether in food cold chains, server rooms, or industrial production processes. In addition to monitoring, the device also supports long-term data logging — thanks to the integrated temperature data logger with a storage capacity of up to 20 years.

The Web-Thermometer 8x from Wiesemann & Theis offers the perfect balance between functionality, network integration, and ease of use. The browser-based web interface provides technicians and facility managers with instant access to real-time data streams, charts, trend analyses, and event logs. Since no additional software installation is required, integration is particularly easy, even in existing network environments. This combination of ease of operation, robust technology, and precise data acquisition makes the Web-Thermometer 8x a professional solution for the industrial, IT, and energy sectors.

Technological Advantage through Multi-Sensor Precision

The main advantage of the Web-Thermometer 8x lies in its ability to record eight independent measurement points simultaneously and evaluate them in parallel. In industrial scenarios, this multi-channel capability allows the simultaneous monitoring of several process sections or devices. Server room administrators can use a single device to measure the temperature distribution at various rack positions and identify critical hotspots in real time. This reduces overheating risks while increasing cooling efficiency.

Each channel can be configured individually for specific sensor parameters. Different sensor types can be combined, calibration factors stored, and alarm thresholds defined separately. This flexibility makes the system ideal for heterogeneous infrastructures—such as in building technology, laboratories, or automated production facilities where different temperature zones must be continuously monitored.

Powerful IoT Integration and Data Security

The Web-Thermometer 8x is designed as a fully integrated component of modern IoT architectures. It transmits measurement values in real time and can be easily integrated into existing systems for building, energy, or process automation. Through MQTT and OPC UA, the device communicates directly with SCADA systems or cloud platforms. This opens up a wide range of automated applications—from adjusting cooling power in data centers to controlling industrial heating processes. With the REST interface, custom applications or data evaluations can be developed to embed the collected data into existing systems.

Data security is a top priority at Wiesemann & Theis. All data transmissions are encrypted via TLS connections. User accounts, roles, and access rights ensure that only authorized users can modify configurations or view measurement data. Local backup mechanisms of the temperature data logger ensure that sensor values are not lost even during network outages. This decentralized approach ensures maximum reliability in any network topology.

Application Fields of the Web-Thermometer 8x

• Server rooms and data centers: Distributed temperature measurement at multiple rack positions.
• Industrial plants: Process-oriented temperature monitoring at different production stages.
• Building technology: Centralized climate data recording across several zones.
• Energy industry: Monitoring transformer stations, pumps, or substations.
• Agriculture: Temperature control in greenhouses and livestock facilities.
• Logistics and transport: Cold chain monitoring to ensure product freshness.
• Healthcare and pharmaceuticals: Compliance with storage temperatures for medicines and samples.
• Research and laboratory technology: Temperature analysis for experimental setups and long-term studies.
• Automation and smart building: Energy-efficient control via networked sensors with cloud connectivity.

Efficiency and Analysis in Continuous Operation

The Web-Thermometer 8x is designed for 24/7 operation. Its power supply via Power over Ethernet reduces installation costs and enables central power monitoring. The electronic stabilization of the device ensures consistent measurement precision under all environmental conditions. Since each sensor can be individually calibrated, the system is highly adaptable. All measurement points can be displayed graphically in real time via the web interface, and built-in filters make statistical evaluation easier.

The built-in temperature data logger stores data sets for decades, allowing the entire temperature history of a system to be traced. These data provide the basis for energy analysis, maintenance strategies, and efficiency optimizations. Metrics can also be exported or processed directly in higher-level management systems. Wiesemann & Theis places great importance on intuitive use, ensuring the system supports every user—from service technicians to data analysts.
