COMET T4511 – WebSensor for External Pt1000 Probe -200 to +600 °C

COMET T4511 WebSensor Pt1000 Ethernet 

The COMET T4511 is a professional Ethernet WebSensor (T-Line) designed for external Pt1000 temperature probes – the ideal solution for high-precision, network-based temperature monitoring in industry, process control, refrigeration systems, laboratories, warehouses, heating, ventilation, and air-conditioning applications. With a measuring range from –200 to +600 °C and an accuracy of ±0.2 °C, it is perfectly suited for demanding applications where standard sensors reach their limits.

The sensor supports all common Pt1000 probes (sold separately) and converts temperature readings with the highest precision into digital values (resolution 0.1 °C). The large dual-line LCD clearly displays current values and can be switched off during continuous operation. Via Ethernet (RJ45), the T4511 integrates seamlessly into networks – with direct connection to the COMET Cloud (3 months free, then 1 credit/year) for charts, exports, alarms, and remote access via app or browser.

The T4511 supports Modbus TCP, SNMP, JSON, or XML for integration into your own SCADA/BMS/IoT solution. The robust housing (IP30) and the operating temperature range of –30 to +80 °C make it a reliable partner for demanding industrial use – indoors or outdoors. Optionally, it can be powered via PoE – just one cable for both data and power.

The sensor is maintenance-free, long-term stable, and supplied with a traceable calibration certificate – ensuring top quality and traceability. Ideal for applications using Pt1000 probes in low-temperature, process, or high-temperature environments.
