Process Instrumentation


The SITRANS TF280 is a WirelessHART temperature transmitter that provides all measured process values as well as diagnostic information, parameters and functions via radio. The device is powered by an internal battery and designed for ultra low power consumption. Its compact and rugged design makes it specially suitable for direct mounting on tanks and pipes in remote parts of plants, and on moving or rotating equipment for process monitoring or asset management applications.


  • Safe communication - very high security level for wireless data transmission

  • Practical push buttons - Three push buttons for setup, diagnostics, communication and security settings 

  • Optimized power consumption - Sleep mode for efficient battery life management

  • Flexible mounting - Extension cable for separate installation of the sensor

  • Physical HART maintenance port for commissioning
