All models on this page share the same COMET measurement accuracy — the right choice comes down to how the reading needs to reach your system:
The industry-standard analogue current loop for PLC/SCADA integration over long cable runs. See 4-20mA Temperature Transmitters.
Voltage output for BMS and controllers that read 0-10V rather than current loops. See 0-10V Temperature Transmitters.
Network-connected WebSensors with built-in web server, email/SMS alarms and optional Power over Ethernet. See Ethernet and PoE Temperature Sensors.
Wireless sensors for sites without run-in Ethernet cabling, with local display and optional COMET Cloud logging. See WiFi Temperature Sensors.
Serial outputs for direct PC/PLC connection (RS232) or multi-drop industrial networks (RS485). See RS232 and RS485 Temperature Transmitters.
Built-in models measure at the sensor body itself — the simplest install for ambient/room monitoring. Remote-probe models connect to an external Pt1000 or T+RH probe on a cable, letting the electronics sit outside the measured environment — the right choice for ducts, compressed air, ovens or any space too harsh or inaccessible for the sensor body itself.
A sensor (RTD, thermocouple or similar) detects temperature; a transmitter converts that raw signal into a stable, standardised output — 4-20mA, 0-10V or a digital protocol — that can travel long distances to a PLC, BMS or SCADA system without signal loss. Every COMET model on this page combines both in one unit.
4-20mA and 0-10V are the standard choices for PLC/BMS analogue inputs over long cable runs. Ethernet and PoE suit networked sites needing remote web access and email/SMS alarms. WiFi suits sites without existing network cabling. RS232 suits a direct single-device PC/PLC link; RS485 suits multi-drop industrial networks with several sensors on one bus. See the comparison above.
