This device combines advanced sensor technology with a user-friendly interface and comprehensive network functions, making it ideal for use in server rooms, industrial environments, and offices. In this article, we present the technical specifications, possible applications, and advantages of this innovative measuring device that takes temperature monitoring to a new level.

High-Precision Measurements with Pt100/Pt1000 Sensors

The Web Thermometer is equipped with a Pt100 temperature sensor, included in the delivery, which measures temperatures in the range of -50 °C to +180 °C. The measurement input supports an extended range from -200 °C to +650 °C, making it suitable for a wide variety of applications. Compatibility with Pt100 and Pt1000 sensors ensures high accuracy and stability, which is particularly advantageous in demanding environments such as industrial processes or server rooms. The terminal connection allows secure and easy sensor integration, simplifying installation and maintenance. This precision is critical for avoiding equipment damage, improving energy efficiency, and reducing operating costs.

User-Friendly Configuration via Web Interface

Operating the Web Thermometer is extremely simple thanks to an intuitive web interface. Without additional software, users can access real-time temperature data, analyze trends, and adjust settings via a standard web browser. The graphical display of temperature trends helps identify patterns and potential issues. This user-friendly interface allows for rapid commissioning and customization to individual requirements, making the device ideal for both experienced IT administrators and newcomers. Whether in network cabinets, server rooms, or production halls – the ease of use makes the Web Thermometer a versatile solution.

Comprehensive Alarm and Reporting Functions

A standout feature of the Web Thermometer is its ability to automatically trigger alarms when temperature thresholds are exceeded. Up to 12 individually configurable alarm messages can be set up and sent via email, SNMP trap, or Syslog. This functionality is particularly valuable in critical environments like server rooms, where temperature fluctuations can lead to costly failures. Additionally, the device includes a reporting function that sends regular summaries of the measurement data via email. These reports are ideal for audits, energy analyses, or documentation of operating conditions, and enhance transparency in monitoring.

Seamless Integration into Modern Networks

The Web Thermometer 1x Pt100/Pt1000 is fully equipped to meet the demands of Industry 4.0 and IoT applications. It supports modern protocols such as OPC UA, REST, and MQTT, enabling easy integration into existing automation systems. It also provides interfaces like SNMPv1, SNMPv2c, SNMPv3, Modbus-TCP, OPC DA, and Sensobase for integration into databases via ODBC. Developers can access the measurement data directly via TCP or UDP sockets to develop custom solutions. The HTTP interface additionally allows direct access to current readings, for example via JavaScript (AJAX), making it possible to embed values dynamically into other websites or applications. This extensive connectivity makes the device an indispensable tool for networked environments.

Long-Term Data Storage and Global Access

An integrated data logger stores temperature values for a period ranging from a minimum of 16 weeks to a maximum of 20 years, depending on the selected storage frequency (15 seconds to 1 hour). The data can be exported in various formats such as FTP, Excel files, or email attachments, enabling flexible post-processing. Connection to the W&T Cloud provides global access to the logged measurement data, meaning it is available anytime from anywhere. An internal, battery-buffered clock ensures accurate timestamps, which are further improved by synchronization with a time server. These features ensure reliable documentation and analysis of temperature trends.

Versatile Application Possibilities

The Web Thermometer 1x Pt100/Pt1000 with terminal connection is designed for a wide range of applications. In server rooms and network cabinets, it monitors ambient temperature to prevent overheating and extend hardware lifespan. In office environments, it helps optimize air conditioning, improving comfort while reducing energy costs. In industrial settings, the device is ideal for monitoring processes where precise temperature control is critical. In the context of Green IT, the Web Thermometer supports more efficient use of climate control systems in data centers by providing precise data to optimize cooling. The terminal connection enables secure and simple sensor integration, further enhancing the device’s flexibility.

Flexible Power Supply and Standards Compliance

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

Please note: NO power supply is included in the delivery.

Durability and Reliability

The Web Thermometer is designed for continuous operation and includes a five-year warranty. Its robust construction and support for DIN rail mounting make it ideal for industrial environments. The internal clock, buffered by a battery, ensures accurate timekeeping, further refined by synchronization with a time server. These features underscore the device’s long-term reliability and durability, even under challenging conditions.
