Sensitron SMART S MS Insatech

The Sensitron SMART S-MS is a Zone 1 fixed gas detector from the SMART S series and Sensitron's most customisable detector model. It detects flammable and refrigerant gases using catalytic and infrared sensors, and is the only model in the SMART S range to carry MED (Marine Equipment Directive) certification - alongside ATEX, IECEx, ECAS-Ex, Lloyd's Register Marine, and CCS certification.

Key Advantages:

  • Zone 1 / ATEX Category 2, IECEx and ECAS-Ex certified
  • MED certified — approved for use on EU-flagged vessels
  • Lloyd's Register Marine and CCS certified
  • Sensitron's most customisable detector platform
  • RS485 and 4–20 mA output as standard, with 3-relay output board
  • SIL2 hardware / SIL3 software certified

We deliver directly and globally to end-users, agents, and resellers.

Detectable gases

The SMART S-MS is available in sensor-specific variants. The gas type must be matched to the correct sensor at time of order.

Catalytic sensor: Flammable gases: methane (CH₄), LPG, butane, propane, and other hydrocarbons

Infrared (IR): CO₂, SF₆, and refrigerant gases

PID: VOC (volatile organic compounds)

The Only SMART S Detector with MED Marine Certification

For ship operators and shipyards specifying gas detection for EU-flagged vessels, MED certification under Directive 2014/90/EU is a requirement for safety-critical equipment installed on board. The SMART S-MS is the only detector in the SMART S series to carry MED certification - alongside Lloyd's Register Marine and CCS approval - making it the appropriate choice when both the high-customisation capability of the SMART S platform and formal marine type approval are required simultaneously.

Beyond marine, the SMART S-MS is equally suited to offshore platforms, industrial facilities, and other installations where Zone 1 classified areas require a configurable, high-specification detector with a broad certification portfolio. Its RS485 output as standard and 3-relay board support integration with both marine control systems and land-based building management and process control infrastructure.

MED, Lloyd's Register, and CCS - What the Certifications Mean for Buyers

For operators specifying gas detection for formally certified vessel installations, understanding which approvals are required is as important as selecting the correct sensor type. The SMART S-MS carries three marine-specific certifications in addition to its ATEX, IECEx, and ECAS-Ex approvals:

MED (Marine Equipment Directive, 2014/90/EU) - required for safety-critical equipment installed on EU-flagged vessels. MED certification means the product has been assessed against harmonised standards and is approved for use in the EU maritime regulatory framework. For shipyards and operators fitting out or retrofitting EU-flagged vessels, MED-certified equipment is not optional - it is a compliance requirement.

Lloyd's Register Marine - type approval from one of the world's leading classification societies. Lloyd's Register approval is recognised globally and is commonly specified by owners and operators managing internationally trading vessels, regardless of flag state.

CCS (China Classification Society) - type approval recognised for vessels classed under CCS, which covers a significant share of the global newbuild market. For operators or shipyards sourcing equipment for CCS-classed vessels, CCS-approved products are required.

If you are unsure which certifications apply to your vessel or installation, contact our team and we will advise based on your flag state, class society, and project requirements.
