COMET T7611 – PoE WebSensor for Temperature, Humidity, and Barometric Pressure

COMET T7611 – PoE WebSensor with external cable probe for temperature −30 to +105 °C, humidity, barometric pressure 

The COMET T7611 is the high‑performance PoE WebSensor (T‑Line) for simultaneous measurement of temperature, relative humidity, and barometric pressure – featuring a remote combined probe and Power over Ethernet (IEEE 802.3af). As a true remote thermometer‑hygrometer‑barometer with Ethernet interface, external probe, and PoE power supply, it is the ideal solution for flexible and professional monitoring in server rooms, technical areas, warehouses, clean rooms, greenhouses, production facilities, or meteorological stations.

The high‑precision capacitive polymer humidity sensor and excellent barometric pressure sensor ensure maximum accuracy and long‑term stability. The probe measures temperature up to +105 °C and humidity from 0–100 %RH. In addition to primary values, the T7611 automatically calculates all essential humidity parameters: dew point, absolute humidity, specific humidity, mixing ratio, and specific enthalpy – all instantly available via the integrated web interface or Modbus TCP.

The large dual‑line LCD can display temperature, humidity, pressure, or dew point and can be switched off for continuous operation. Via Ethernet (RJ45) with PoE, the sensor integrates seamlessly into networks – power and data through a single cable! Direct connectivity to COMET Cloud (3 months free, then 1 credit/year) provides charts, exports, alarms, and remote access via app or browser. Alternatively, Modbus TCP, SNMP, JSON, or XML can be used for your own SCADA/BMS/IoT system.

The robust housing and operating temperature range from –20 to +60 °C (probe up to +105 °C) make the T7611 a reliable device for continuous industrial use – indoors or outdoors. PoE simplifies installation, reduces wiring, and saves costs – no separate power supply needed!
