COMET P2520 – 2-Channel WebSensor for 0-20mA

COMET P2520 – Ethernet WebSensor with 2 channels for 0–20 mA / 4–20 mA signals, ±0.1 % FS accuracy      

The COMET P2520 is a professional Ethernet WebSensor (P-Line) with two channels for 0–20 mA / 4–20 mA signals – the ideal solution for network‑based monitoring of process variables such as pressure, level, flow, pH, conductivity, or other analog sensors. The sensor converts analog current signals into precise digital values (±0.1 % FS from 0 to +50 °C; ±0.3 % FS from –30 to +80 °C) and transmits them directly via Ethernet – perfect for building automation, Industry 4.0, process control, or remote monitoring.

Each channel features a 24‑bit sigma‑delta converter for maximum resolution (1 µA) and an input resistance of only 20 Ω – minimal load for connected sensors. The measuring interval is 1 second. The P2520 supports all standard 0–20 mA and 4–20 mA sensors and comes with a traceable calibration certificate – ensuring the highest quality and traceability.

Via Ethernet (RJ45), the sensor integrates seamlessly into networks. Direct connection to the COMET Cloud (3 months free, then 1 credit/year) provides charts, exports, alarms, and remote access via app or browser. Alternatively, it supports Modbus TCP, SNMP, JSON, or XML for your own SCADA/BMS/IoT solution. Optional PoE (Power over Ethernet) operation – one cable for both data and power.

The robust housing (IP30) and operating temperature range from –30 to +80 °C make the P2520 a reliable partner for demanding industrial applications – indoors or outdoors. The sensor is maintenance‑free and ensures long‑term stability – made by COMET.
