Gas Detector Cartridge For Combustible/Flammable Gases Along With RS 485 Interface Sensor Board

ALVI Automation also trading as GasAlarm brings to you a revolutionary product in the field of Flammable/Combustible Gas Detectors.

Sensor Cartridge SC2 for combustible gases

SC2 sensor cartridge

Exchangeable sensor including digital value processing, temperature compensation and self-control for the continuous monitoring of the ambient air.


The PolyGard®2 Sensor Cartridge is used for the detection of combustible gases in non-Ex zones.


  • Digital measurement value processing incl. temperature compensation
  • Internal functional control with integrated Hardware Watchdog
  •  Data / measured values in μC Sensor Cartridge, therefore simple exchange of SC uncalibrated <> calibrated
  •  High accuracy, selectivity and reliability
  •  Low zero point drift
  •  Sensor with long life expectancy
  •  Hardware & software according to SIL2 compliant development process
  •  Modular technology (plug-in and replaceable)
  •  Easy maintenance and calibration by exchange of the sensor cartridge or by comfortable on-site calibration
  •  Reverse polarity protected, overload and short-circuit proof
  •  IP 65 version
  •  Conformity to
    o EN 50271
    o EN 61010-1
    o ANSI/UL 61010 1
    o CAN/CSA-C22.2 Nr. 61010-1

Flammable / Combustible Gases sensor – online transmitter / Detector / Analyzer / Monitoring , Non Ex-proof area

Combustible gases (flammable ) detectors / Sensor Transmitters by world-class German technology

Gas detector or sensor transmitter for online, continuous monitoring of all combustible or flammable gases as below. These transmitters offer industry standard analog output in current or voltage form, or digital signals like Modbus RTU with RS485 serial interface.

Optionally, these are also equipped with potential free relays.

These can be mounted on wall, ceiling, columns, ducts or pipelines. These can be a single gas or multi-gas detection transmitters.

Nonexplosion proof sensor or detectors can be installed at non-hazardous area classified areas like kitchen, canteen, building, store rooms, warehouse, cold stores, offices, theatre, mall etc.
