SENSECOM-IMNT

Remote impulse readings with data transmission via nationwide NB-IoT

  • Remote consumption reading of electricity, water, gas, etc. based on pulse sensors
  • Primary input
    • CNT0, CNT1 – voltage-free* inputs for pulse meter readings.
      • The CNT0 input can split the pulses into 2 counters according to the medium flow direction.
    • DIR – voltage-free* input used to differentiate the medium flow direction
    • DI – Voltage-free* digital input (without galvanic isolation), used e.g. for intrusion or flood detection.
  • Secondary voltage-free input
    • reading from a gas meter / water meter equipped with a voltage-free contact*
  • Power supply
    • lithium battery size “C” (type SAFT LS 14 3.6 V, 5.8 Ah).
    • Life >10 years at 1h readings with 12h message period
  • outdoor design, IP67
  • Models:
    • IMNT – 1x M12 grommet
    • IMNT2 – 2x M12 grommet
  • External NB antenna via SMA connector
  • Broadcasting to the NB-IoT nationwide network
  • Optional E2E encryption using AES256

*Alternatively open collector output limited to max. 0.5 V at max. 0.5 mA in closed state. The input is not galvanically isolated (n/a for battery models)
