Through the LCD display the SI-100 shows the concentration of gases present and the status of the unit in real time. Connected to a controller or PLC with a standard 4-20mA analog output.
Battery Room Monitoring | The SI-100C and a range of associated Gas Detection Australia controllers can be used in battery room gas detection to detect hydrogen in battery rooms and sound alarms. The battery room gas detection systems comprise of a hydrogen gas sensor SI-100C and a gas sensor control unit. The Gas Detection Australia control unit GDA 4020 or GDA 4011 is situated external to the battery room to display the gas concentrations and the alarm status. The battery room gas detection system can then be interfaced to extraction fans, sounders or other apparatus. For smaller battery charging rooms the standalone GDA 40126 can provide an integrated sensor and controller with outputs to drive extraction fans and sounders. Designed, Manufactured and Supported in Australia. |
Sewage Treatment Plant Monitoring | The presence of Hydrogen Sulphide can be detected by using the Gas Detection Australia GDA 2529 gas sensor to detect leaks of Hydrogen Sulphide and evoke deodorisation plant. The SI-100C gas sensor can be used to monitor for leaks of LEL levels of methane gas. In digester applications Carbon dioxide can be detected using the GDA 4350 Designed, Manufactured and Supported in Australia. |
Hazardous Areas (IEC Ex Certified) | IEC Ex approved gas detectors and sensors for use in Zone 1 and Zone 2 areas within Australia for both Toxic and Flammable gases. Hazardous Areas are areas in which an explosive gas atmosphere is or may be expected to be present, in quantities such as to require special precautions for the construction installation and use of equipment construction, installation and use of equipment. Hazardous areas are classified into 3 zones based upon the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:

Notes
This sounder/flashers operates at 24VDC. The sounder can be permanently disabled so that unit acts as a flasher only. These units are designed for internal use. These are available in Red or Amber.
The IS-A105N is a high output, 105dB alarm sounder. Suitable for all intrinsically safe signalling applications including fire, security and process control.
The IS-L101L unit is an intrinsically safe field mounting beacon which provides a bright
flashing warning signal.
