COMET T7613D – Web Sensor for Temperature -30 to +105 °C, Humidity, and Pressure

COMET T7613D – PoE Duct-Mount WebSensor for Temperature –30 to +105 °C, Humidity, and Barometric Pressure 

The COMET T7613D is the professional PoE duct-mount WebSensor (T-Line) for precise measurement of temperature, relative humidity, and barometric pressure directly in air ducts – with integrated sensors and Power over Ethernet (IEEE 802.3af). As a true remote thermometer‑hygrometer‑barometer for HVAC systems, ventilation, air conditioning, cleanrooms, production halls, or meteorological applications, it is the ideal solution for continuous monitoring of air quality in ducts and pipelines.

The high‑precision capacitive polymer humidity sensor and the excellent barometric sensor ensure maximum accuracy and long‑term stability. The sensor measures temperature up to +105 °C and humidity from 0–100 %RH. In addition to primary values, the T7613D automatically calculates all key humidity parameters: dew point, absolute humidity, specific humidity, mixing ratio, and specific enthalpy – all directly 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 turned off for continuous operation. Via Ethernet (RJ45) with PoE, the sensor integrates seamlessly into existing networks – power and data over a single cable! Direct connection to COMET Cloud (3 months free, then 1 Credit/year) provides graphs, exports, alarms, and remote access via app or browser. Alternatively, Modbus TCP, SNMP, JSON, or XML are available for integration into your own SCADA/BMS/IoT solution.

The robust housing with duct‑mount design and the operating temperature range of –20 to +60 °C make the T7613D a reliable partner for continuous use in ventilation systems. PoE makes installation simpler, cleaner, and more cost‑effective – no separate power supply needed!
