AtEx zone 1 outdoor remote Pulse Sens’O sensor – LoRaWAN


The Pulse Sens’O AtEx zone 1 remotely reads metering data from water, gas (such as Itron, Esther and Gazpar) or electricity in AtEx zone 1 sensitive areas. Pulse Sens’O AtEx zone 1 sensor allows you to make all your mechanical pressure switches communicate with each other in AtEx zone 1 explosive atmospheres. It transforms existing meters into communicating meters via a public or private LoRaWAN® network.

Different versions available:


  • LoRaWAN®, Class A
  • Easy to install and use
  • 3 pulse inputs or status reports.
  • SAFT LS17500 Lithium battery on holder.
  • Differential data compression.
  • IP55 or IP68.
  • 10 years of autonomy (data compression mode).
  • AteX Zone 1 certification according to marking:
    – Ex II 2 GD
    – Ex ib IIB, IIC T4 Gb
    – Ex ib IIIC T135°C Db
    – -20≤ Tamb≤ +50°C


  • In explosive atmospheres, read index values from gas, electricity, water or heat meters with pulse output; monitoring the charge curve.
  • Detection of leaks, fraud and tearing off .
  • Checking the condition of the mechanical pressure switches located in sensitive areas.
  • Fast and economical solution that transforms any pulse meter into a communicating meter.
