The HW group Temp‑1W‑UNI Pt100 is a professional Pt100 temperature sensor designed for precise temperature measurement across a wide range from –50 °C to +200 °C. With its high‑quality Pt100/A probe and a 2‑meter flexible silicone cable, this sensor ensures reliable results even in demanding environments such as industrial facilities, outdoor installations, or research laboratories.

A key feature of this sensor is the integrated 1‑Wire UNI converter (Converter 2xPt100 1W‑UNI), which enables accurate digital data transmission even under harsh conditions. This technology ensures that measurement values are transferred directly and without signal loss to the connected monitoring system. Using the standardized RJ11 connector, the Temp‑1W‑UNI Pt100 integrates seamlessly with HW group devices such as Poseidon2 or Ares.

Another major advantage of the system is its expandability: in addition to the integrated Pt100/A probe, a second Pt100 or Pt1000 probe can be connected. This allows for simultaneous monitoring of two measurement points, which is especially useful for process control, environmental engineering, or complex industrial applications.

Thanks to its robust design, the Temp‑1W‑UNI Pt100 is ideally suited for use in production halls, outdoor facilities, or scientific laboratories where precise temperature measurement is essential for the success of sensitive processes.

Technical Specifications of the HW group Temp‑1W‑UNI Pt100

• Measurement range: –50 °C to +200 °C
• Precision Pt100/A probe with 2 m silicone cable
• Integrated 1‑Wire UNI converter for digital data transmission
• RJ11 connector for easy integration
• Connection option for a second Pt100 or Pt1000 probe

Integration into HW group Monitoring Systems

Via the RJ11 interface, the sensor connects directly to HW group devices such as Poseidon2, Ares, or STE2. Once connected, the sensor is automatically detected, requiring no extensive setup. Recorded temperature values can be monitored in real time, and alarm alerts can be triggered when defined temperature thresholds are exceeded or undershot.

In combination with the SensDesk.com IoT portal, centralized online management becomes possible. Users can monitor multiple locations simultaneously, analyze historical temperature data, and automatically generate reports. These features are particularly valuable for regulated industries and quality‑critical processes.
