SMART 3G

Safety for all applications
SMART 3G series detectors are used in
various application areas, including the paper industry,
food and beverage, and cosmetic industry.

The gas detectors of the SMART 3G series are used to detect the presence of flammable substances, toxic gases, refrigerants, as well as to detect deficiencies or excess of oxygen in both classified and non-classified areas.

Gas detectors with displays suitable for Zone 1 Category 2.

The SMART3G-D2 allows for non-intrusive field calibration using Hall effect sensors, enabling operation on the device using dedicated magnets without the need to open it or declassify the area.

Basic Board

Power Supply 12-24 Vdc 12-24 Vdc
Analog Output Uscita 4-20mA
Digital Output (optional) RS485 serial output through the ST.S/IDI card
Relay Outputs (optional) 3 relay outputs through the STS3REL card
The basic board is tropicalized.
Tropicalization is a protective barrier against environmental factors such as dust, humidity, or other contaminants that could adversely affect the operation of the assembled circuit.
Certified hardware at SIL2 and software at SIL3; by creating a redundant system, even the hardware achieves a safety level of SIL3.

Gas detectors with displays suitable for Zone 1 Category 2.

The SMART3GD-C2-LD version is equipped with a high-brightness LED ring, which allows you to visualize the alarm status of the detector.
