Ethernet temperature, humidity and CO₂ sensor with PoE Comet TA3645
Ethernet temperature, humidity and CO₂ sensor with PoE Comet TA3645
Comet TA3645 is a professional Ethernet monitoring unit designed for accurate measurement of temperature, humidity, and CO₂ concentration in industrial, laboratory, and technical applications. It combines two inputs for highly accurate Pt1000 temperature probes with one digital input for a temperature and humidity probe or a CO₂ sensor. This combination allows multiple environmental parameters to be monitored simultaneously using a single device.
The unit is particularly suitable for applications where extreme temperatures must be monitored while also maintaining control over ambient environmental conditions. Pt1000 probes enable measurements across a wide temperature range, depending on the selected probe type, making the TA3645 an ideal solution for cold storage facilities, freezers, cryogenic applications, laboratories, pharmaceutical environments, and industrial processes.
Thanks to Ethernet connectivity and PoE support, the device can be easily integrated into existing network infrastructure. Both power and data communication can be provided through a single Ethernet cable, reducing installation complexity and lowering deployment costs.
Measured values can be monitored through the built-in web interface or via COMET Cloud. Users gain continuous access to real-time data and can configure automatic alarm notifications whenever predefined limits are exceeded.
The TA3645 is designed for integration into professional monitoring, automation, and Building Management Systems (BMS). It supports Modbus TCP and SNMP communication protocols and offers secure communication via HTTPS, TLS, and SNMPv3. Support for both IPv4 and IPv6 ensures compatibility with modern enterprise networks.
A large backlit LCD display provides instant access to measured values directly at the installation site. The device also includes LED alarm indication and audible alarms for rapid detection of abnormal conditions.
