Custom solutions for each application


With the Marine line, Sensitron develops a gas detection system certified by Lloyd’s Register according to MED/3.54. MULTISCAN++MED control panels and SMART S-MS MED detectors meet the EMC and environmental requirements of the marine sector.
MULTISCAN++MED control panels are also ATEX-certified and meet SIL2 functional requirements.
The SMART S-MS MED detector is designed to withstand the harsh conditions of the marine environment. It is equipped with a catalytic sensor or infrared sensor to detect flammable gases. The detector is also compliant to SIL 2 Hardware, SIL 3 Software and certified ATEX for Zone 1 with marking II2G Ex db IIC T5 Gb.

Linea Marine



SMART S-SS and SMART S-MS single sensor head and single output

The gas detection system consists of MULTISCAN++MED gas control panels and SMART S-MSdetectors, both purposely designed and certified to meet with the Marine requirements. The system has been certified by the Lloyd’s Register in accordance with MED/3.54 Regulation. The MULTISCAN++MED are advanced multifunction gas detection control panel designed to meet with the increasing requests for highly flexible systems. They come complete with specific software that makes them suitable to be used in SIL2 plants. A powerful microprocessor allows a wide range of self-testing facilities to take place to detect and localize possible failures. The system allows the connection of gas detectors and remote input/output modules via 2 closed loops. The control panels can manage and monitor up to 64 gas detectors. These can either be addressable detectors, daisy chained on the available loops, or analog type with 4-20mA transmission, connected via remote 8 input cards STG/IN8-S2. The system architecture includes 8 preset relays onboard the units and the possibility to have further 128 open collector outputs via remote STG/OUT16-S2 output cards. To these cards it is possible to connect 8-relays boards, should relay outputs be required.


Designed to meet with the harshest conditions of Marine environments, SMART S-MS MED line allows to monitor flammable gas contents both by employing catalytic or infrared technologies.

These detectors have been certified to SIL 2 Hardware SIL 3 Software capability and are ATEX certified for zone 1 as II2G Ex db IIC T5 Gb.

SMART S-MS line has also been Marine certified by Lloyd's Register.

  • Electronic with1 output RS+4-20 mA
  • 3-relay card Output
  • SIL2 Hardware &  SIL3 Software Certified
  • Certified by Lloyd's Register

Custom solutions for each application


 All devices connected to the loops feature galvanic isolation to protect the system from any electric noises coming from the field. A broad range of self-testing facilities are implemented to detect and localize possible faults.

The backlit graphic LCD display provides a precise indication of the gas concentration being measured. A RS232C serial port allows the PC connection to the CPU board for the panel configuration and supervision.

Report from the event memory or real-time printouts can be obtained by connecting a printer to the parallel printer port.

The panels are supplied in a robust metal cabinet.
