HW group Sensors and the PHTemp‑485T7410 – Triple Measurement Sensor for Industrial and IT
The HW group PHTemp‑485 T7410 is a high‑performance, versatile sensor that simultaneously measures temperature, humidity, and barometric pressure. Combining highly precise measurement technology with a robust design, it is specifically engineered for demanding applications in industry and IT infrastructures. Whether in server rooms, data centers, or the food and pharmaceutical industries, this RS‑485 sensor offers a modern, reliable solution for continuous environmental and climate monitoring.
With a temperature range of –30 °C to +80 °C, relative humidity from 0–100 % RH, and an air pressure range of 600–1100 hPa, the PHTemp‑485 T7410 covers all relevant climate parameters. Measurements are taken with high accuracy: ±0.4 °C for temperature, ±2.5 % RH for humidity, and ±1.3 hPa for pressure. In addition, the sensor calculates key climate indicators such as dew point, absolute and specific humidity, and enthalpy, enabling deeper analysis of air quality.
The RS‑485 interface with terminal block allows direct integration into monitoring devices such as HW group Poseidon2 4002 or Poseidon 2250. Communication uses an ASCII protocol, making it easy to integrate into existing control and data acquisition systems. An integrated LCD display provides instant on‑site readouts of all measured values, making data readily accessible for operators.
The PHTemp‑485 T7410 is not only precise but also energy‑efficient: it requires just 10 mA of current during operation and can be powered either through Poseidon devices or via external power sources between 10–35 V DC. Its rugged IP40 housing protects sensitive components from contamination and mechanical influences, while its compact dimensions (168 × 90 × 40 mm at 168 g) make installation easy in control cabinets, server racks, or production environments.
