€296.00
Comet TA4621, the compact Ethernet sensor for two external Pt1000 probes, two independent inputs, measuring range minus 200 to plus 260 degrees Celsius, accuracy plus minus 0.2 degrees Celsius, CINCH connector, inter-channel calculations, backlit LCD display, acoustic and LED alerting, PoE
The Comet TA4621 is the compact Ethernet sensor for precise temperature measurement with two external Pt1000 probes. This model offers two independent inputs with an optimized measuring range from minus 200 to plus 260 degrees Celsius and an accuracy of plus minus 0.2 degrees Celsius. The probes are connected via practical CINCH connectors, so one device can simultaneously monitor temperature differences or two separate measuring points.
The Comet TA4621 features a backlit LCD display, full alarm signaling with LED and acoustic warning, and PoE support. Important functions include inter-channel calculations and software-based compensation of probe cable error. This makes the TA4621 ideal for demanding industrial processes, the simultaneous monitoring of two freezers, or integration into higher-level systems.
The Comet TA4621 offers a power supply of 5 to 24 volts or PoE. It has integrated backup memory and a modern web interface with IPv4 and IPv6 support, Modbus TCP, COMET Cloud, as well as fully encrypted communication via HTTPS, SNMPv3, and TLS. An integrated removable holder makes installation easier. The device belongs to the TAx6xx series, the new generation of Web Sensor 2.0 premium sensors.
The Comet TA4621 combines precise measurement, modern network communication, and local monitoring via LCD display, LED signaling, and acoustic alarm. Local monitoring without a PC is provided through the backlit segmented LCD display with four brightness levels, display of values, alarms, and IP address, tri-color LED signaling green yellow red, and acoustic alarm with local and remote mute option. The device is ideally suited for server rooms and data centers, laboratories and healthcare facilities, industrial plants, offices, schools, public buildings, and cleanrooms.
