smart/ECS Multi Gas Sensor

JES Tunnel Safety offer the Smart/ECS, an IoT-enabled gas sensor that can detect up to four gases: (CO, NO, NO2, SO2 – other gases on request).

Features

• Smart IoT enabled gas sensor
• Electrochemical measurement of gas concentration with up to 4 gas sensor modules
• Pre-calibrated gas sensor modules for different gases and measuring ranges, including CO, NO, NO₂, SO2
• Installation in-situ in the tunnel’s driving area or extractive with hose adapters
• Stainless steel housing 1.4404 (AISI 316L)
• Sensor protected against splashing of water and powerful water jets used for tunnel washing
• IP rating IP69K
• Optional LCD in housing cover
• Integrated web server for visualisation, configuration, data logging, remote maintenance
• Connection to tunnel control system by
  • MODBUS/TCP (Ethernet)
    
  • MODBUS RTU (RS-485)
    
  • Analogue and relay outputs (optional)
  • OPC UA (Ethernet)
• Optional smart/HUB IoT operating and control unit with touch display

System Set-up

• Smart IoT sensor for up to 4 gas sensor modules
• Exchangeable, pre-calibrated gas sensor modules
• Connection either to tunnel control system or optional oper-ating and control unit smart/HUB

Operation

Gas monitoring during normal operation is used to control the tunnel ventilation at normal operation. If and with how much power artificial ventilation by jet fans is operated depends on the measured visibility and gas concentration.

Electrochemical gas sensor cells induce currents proportional to the prevailing gas concentration. With these currents and the measured temperature, the gas sensor modules calculate the gas concentrations.

Advantages
