As a recognized manufacturer of high-quality monitoring components, W&T stands for technical innovation, reliability, and quality. The Web Thermometer NTC is the result of this expertise – well thought-out in every detail and designed with a focus on practicality and longevity. W&T places particular emphasis on sustainable production and energy-efficient electronics that meet the highest environmental standards.

The devices are developed, tested, and assembled in Germany. This guarantees short delivery routes, maximum quality assurance, and professional support. For operators of critical infrastructures, reliability is just as important as functionality – a demand that the web thermometer series from Wiesemann & Theiss fully meets. With a guaranteed lifetime of several years, robust components, and a future-ready system architecture, the Web Thermometer NTC ensures long-term operational security.

IoT-Based Real-Time Temperature Monitoring

The NTC Web Thermometer uses the latest IoT technologies to capture temperature data in real time and transmit it seamlessly to a central platform. All measured values are immediately available via the integrated web interface. Alternatively, the device can be connected to external visualization or process control systems via API interfaces. Thanks to support for IoT protocols, the web thermometer can easily be integrated into smart building or Industry 4.0 systems.

The cloud-based architecture enables global access to current measurement data. Through secure connections, users can analyze temperature trends, review alarm histories, or use export functions. The graphical visualization in the browser or app allows temperature histories to be displayed clearly – a major benefit for operators who want to take preventive measures early.

Precision NTC Temperature Sensor – High Accuracy Across a Wide Range

The core of the web thermometer is the highly sensitive NTC temperature sensor. It is characterized by excellent response time and minimal deviation (<0.3°C). Combined with the device’s digital signal processing, this ensures extremely precise measurement results. The sensor covers a wide temperature range from -45°C to +75°C, making it suitable for both ambient monitoring and industrial production processes.

Thanks to the intelligent calibration technology of the NTC sensor, temperature fluctuations are immediately detected and traceably documented. This is particularly important in sectors such as research, food production, or pharmaceuticals, where even minor temperature deviations can have critical consequences. With this precision, the device supports compliance with legal documentation requirements and standards.

Cloud-Based Temperature Monitoring and Alarm Management

The Web Thermometer NTC is connected to a highly secure, cloud-based database, allowing users global access to their temperature data. The cloud services enable safe storage of measurement data for up to 20 years, with full retrieval at any time. Trends, curves, and alarm logs can be analyzed in detail. This long-term data logging forms the foundation for predictive facility management and energy optimization.

One of the key features is its comprehensive alarm management. Up to 12 temperature alarms can be individually configured. When predefined thresholds are exceeded or undershot, the system automatically sends a warning via email, app, or SNMP trap. This allows operators to respond immediately in case of malfunctions. The alarm architecture is designed to minimize false alarms while ensuring maximum response security.

Integrated Temperature Data Logger for Long-Term Recording

The device features a built-in temperature data logger that automatically records all measurements. Users can specify second, minute, or hour intervals to collect data in line with their analysis requirements. The stored values can be exported in CSV or XML formats and integrated into other applications. With precise timestamps, the logger ensures reliable tracking of all temperature fluctuations.

This feature is particularly useful for operators of cold storage rooms, server infrastructures, or warehouses subject to strict documentation regulations. Research institutions also benefit from accurate, long-term data acquisition. Thanks to an integrated battery buffer, all data remains safe even in the event of a temporary power loss.
