Dimension : Panel Mounting 100 x 200 x 305 (WHD in mm)

Description

The Model SSI 602 SG detects Combustibles Gases in Air and keep a check on the level by a preset alarm. Typical application are monitoring for pipeline and stroage vessel leakage to assure the combustible gases is below the Lower Explosive Limit (LEL). The Calibration is done typically with Hydrogen and resonds to other combustible gases as per relative response factor. Calibration for other gases is available e.g. Butane. The detector works in 4 to 20 mA Transmitter Model. Optional remote dispaly available. Signal can be taken to PLC / computer to generate Alarms and Reports.

Principle of Operation:

Catalytic Thermal Conductivity for combustible gas detection. In each sensor pair there is a non active compensating reference and an active catalytic sample element. In the presence of combustible gas a signal proportinal to concentration is generated.

Output:

Concentration Level in percentage or LEL in percentage on Digital Dispaly. Please specify options. Recorder output 0-1V DC standard or 4 to 20 mA DC optional.

Alarm:

Preset facility via ten turn direct reading over entire range. Output via panel LED and 1 pole, 2 way relay with NO, C, NC standard on back panel.

The control module is located in a safe area with 220V AC Mains and is cable connected to sensor housed in flame proof enclosure (II A/ II B for LPG, IIC for Hydrogen). the sensor block is made out od stainless steel and has sintered protection barrier. The detector works in 4 to 20 mA Transmitter configuration for output. Optional Flame Proof Powered Flame Prrof loop Reader avaibale.
