Capteur étanche de comptage impulsionnel et mesures analogiques Toran’O AtEx zone 1 LoRaWAN - NKE Watteco

Sensor for remote reading of pulse meters and analog measurement Toran’O - AtEx zone 1 - LoRaWAN - NKE Watteco

Reference: 50-70-150

The Toran'O AtEx zone 1 IP68 sensor is used to report changes of state, pulse counting values and analog measurements of equipment in an AtEx 1 sensitive area such as water, gas, electricity or water meters. thermal energy, mechanical pressure switches, pressure transducers. The sensor does not require any physical connection; its data is sent over a private LoRaWAN radio network (requires a LoRaWAN gateway) or operated (requires a subscription). It can be used in a temporarily submersible area.

Description

Use

- In an explosive atmosphere, the index values of gas, electricity, water or heat meters having a Pulse output are raised. Monitoring of the load curve.
- Leak, fraud and tearing detection (3 entries).
- Status report on mechanical pressure switches placed in sensitive areas of GRTgaz sites.
- Associated with a pressure probe, measurements on the gas network.
