The HW group Temp‑485‑Pt100 Cable3 is a rugged, high‑precision temperature sensor designed specifically for demanding industrial applications and sensitive environments. Featuring an external Pt100/Pt1000 probe connected via a 2‑meter cable, it enables flexible installation directly at the measurement point. With an extended temperature range from –50 °C to +200 °C, the sensor is suitable for both industrial processes and pharmaceutical and food industry applications.

The IP65 protection rating for the converter and IP67 for the stainless‑steel probe ensure reliable operation even in dusty or damp conditions. Thanks to its RS‑485 interface with ASCII protocol (9600Bd 8N1), the Temp‑485‑Pt100 Cable3 transmits precise data securely and stably over long distances. Full compatibility with HW group Poseidon2 devices ensures seamless integration into existing monitoring networks, including alarm functions and data logging.

With a low power consumption of only 2 mA in operation and a maximum of 60 mA during data transmission, the Temp‑485‑Pt100 Cable3 is energy‑efficient and ideally suited for continuous operation in industrial and commercial applications. The compact converter housing (114 × 65 × 35 mm) and external stainless‑steel probe ensure reliable temperature measurement even in hard‑to‑reach areas.

Typical applications include monitoring machinery, production processes, and storage conditions, as well as controlling server rooms and HVAC systems. In regulated industries such as pharmaceuticals and food processing, the sensor is especially valuable for audit‑compliant measurements, meeting stringent hygiene and quality assurance requirements.
