Structural Features: The unit features a compact, sealed enclosure with an internal antenna. It includes LEDs for status indication and a button for manual operation.
Working Principle: The node measures the resistance of the connected RTD sensor, calculates the temperature, and transmits the data wirelessly using Frequency Hopping Spread Spectrum (FHSS) technology to a gateway.
Installation Requirements:
- Mount in a location with adequate radio signal strength.
- Connect the RTD sensor according to the wiring diagram (2, 3, or 4-wire).
- Configure the node parameters via the gateway.
Usage Notes:
- Ensure the RTD sensor type matches the configuration.
- Do not use non-manufacturer supplied parts, as this may void the safety rating.
- Monitor battery status via the gateway.
