Designed to meet the toughest industrial standards, the SMART S-SS series gas detectors are used in classified areas (zone 1 and, if equipped with the dust adapter, zone 21).

The infrared sensor is used to detect flammable substances, refrigerant gases and carbon dioxide; it is not susceptible to poisoning and has high selectivity. The sensor is housed in a stainless steel head with a diameter of 47.5 mm. The detector has a 12-24 Vdc power supply, a 4-20 mA signal output and an RS485 signal.

The SMART S-SS is equipped with a display (LCD or LED) to monitor the concentration in real-time and Hall effect sensors for non-intrusive calibration in the field.

To adapt to the customer’s needs, the SMART S-SS detector has the following customization possibilities:

  • Choice of the sensor head based on the gas to be detected
  • Choice of a transmitter (3-relay board, HART modem)
  • Choice of enclosure (aluminium/steel, number of entrances)
