The HW group Temp‑485‑Pt100 Box2 is a robust, high‑precision temperature sensor designed for demanding industrial and IT monitoring applications. Featuring an RS‑485 interface, a high‑quality Pt100/Pt1000 platinum probe, and an IP65‑rated housing, the sensor delivers maximum reliability in environments exposed to moisture, dust, and mechanical stress. Whether for production‑critical processes, server rooms, or pharmaceutical cold chains, the Box2 provides continuous, accurate temperature data.

The measurement range of this sensor unit spans from –30 °C to +70 °C with an accuracy of ±(0.25 + 0.002|t|). The stainless‑steel tip of the Pt100 probe ensures long‑term stability and corrosion resistance, even in harsh industrial settings. RS‑485 communication via terminal block enables interference‑free and reliable data transmission and integration into systems — even over long distances.

With its compact dimensions (145 × 62 × 35 mm) and weighing 107 g, the Box2 is suitable for wall mounting in technical rooms, production facilities, or HVAC systems. Easy connection to HW group Poseidon2 devices offers the advantage of direct network integration, including data logging, threshold alert systems, and remote monitoring.

The low power consumption of only 20 mA also makes the Box2 a cost‑effective solution for continuous operation in industrial and IT environments. Its rugged IP65 construction protects against dust and water jets, ensuring dependable operation even in open or humid installations.
