Real Time Gas Monitoring System – Gasguard 2

From complete mine wide monitoring and control via fibre or copper to machine gas monitoring systems, Gasguard 2 suits a wide range of applications.

Gasguard 2 comprises of an Intrinsically Safe (Ex ia I Ma) display module which allows for the display and transmission of detector data and system information. Housed within an IP66 rated stainless steel enclosure the display module is available in three variants: a glanded display supporting both digital and analogue, or pluggable versions supporting either digital or analogue.

Technical Data Sheet – Gasguard 2 Monitoring Solution

The Gasguard 2 (GG2) monitoring solution comprises an intrinsically safe GG2 Display Module which allows for the display and transmission of sensor data and system information. The Display Module interfaces to a range of GG2 Detectors for monitoring the atmospheric concentration of the target gas. Ampcontrol supplies a range of accessories for installing, operating and configuring the GG2 Detectors.

Technical Data Sheet – Gasguard 2 Non-dispersive Infra-red Detectors CH4 CO2

The Non-dispersive Infrared (NDIR) CH4 and CO2 models of the GG2 Detector are intrinsically safe sensors for monitoring the atmospheric concentration of Methane (CH4) or Carbon Dioxide (CO2) gas. The stainless steel housing is robust, corrosion resistant and fit for purpose. Power and communications is facilitated through the low profile connector, allowing for quick plug and play connections to compatible models, such as the GG2 Display.

Technical Data Sheet – Gasguard 2 Catalytic Detector CH4

The Catalytic (CAT) CH4 model of the GG2 Detector is an intrinsically safe sensor for monitoring the atmospheric concentrations of Methane (CH4) gas. The stainless steel housing is robust, corrosion resistant and fit for purpose. Power and communications is facilitated through the low profile connector, allowing for quick plug and play connections to compatible models, such as the GG2 Display.

Technical Data Sheet – Gasguard 2 Electrochemical Detectors CO, O2

The Electrochemical (EC) CO and O2 models of the GG2 Detector are intrinsically safe sensors for monitoring the atmospheric concentration of Carbon Monoxide (CO) or Oxygen (O2) gas. The stainless steel housing is robust, corrosion resistant and fit for purpose. Power and communications is facilitated through the low profile connector, allowing for quick plug and play connections to compatible models, such as the GG2 Display.

Technical Data Sheet – Gasguard 2 Display

The Gasguard 2 (GG2) Display Module is an intrinsically safe apparatus for the purpose of displaying and transmitting sensor data and system information. The GG2 Display consists of a certified GG2 Display Module and associated wiring installed within an IP66 rated stainless steel enclosure. The GG2 Display is available in three variants: a glanded display supporting iMAC/RS485 communication and two pluggable versions supporting 4-20mA+iMAC and 4-20mA+RS485 communication. The display connects to a variety of compatible detectors via the robust proprietary connector.

User Manual – Gasguard 2 Detector CH4 O2 CO CO2 Sensor Units

The GG2 Detector is an intrinsically safe apparatus for the purpose of gas concentration level detection and atmospheric monitoring. The equipment is housed in a metallic enclosure with a custom plug interface on the top and is powered by and connected to suitably certified compatible equipment. The GG2 detector can be mounted via the custom plug interface and is secured with the integral retention clip. Optionally, the GG2 Detector may be mounted up to 10 meters away from a compatible module using the optional remote cable assembly. The remote cable assembly allows the GG2 Detector to be installed in an appropriate position for the target gas.

Technical Data Sheet – Gasguard CH4 Sensor (ATEX)

Ampcontrol’s Gasguard Flammable Gas Sensor/Transmitter (ATEX) is supplied complete with an amplifier and a Liquid Crystal Display. The Gas sensor is housed in a cast stainless steel enclosure, has been approved to be intrinsically safe and is suitable for use in a Zone 0 hazardous area. A remote head version with up to ten metres of cable is also available for use on mobile machinery such as roof bolters and continuous miners.

Declaration of Conformity – iMAC Controller

In May 2018, the iMAC / iMAC2 Controller operating system firmware was modified to extend the iMAC Module Serial Number range. These changes occurred in iMAC Controller Operating System Firmware v4.0 (O.S. v4.0). Marcus Punch Pty Ltd was engaged to perform a safety integrity verification of these changes. iMAC2 report AMP-15-01-A1 Revision 3 (including Revisions 4 & 5) and iMAC report AMP-11-05-A2 Revision 2 (including Revisions 3 & 4) assessed these changes to be in compliance with the requirements pertaining to software modification and as a result the existing safety metrics (PFD and PFH) for the iMAC Controller, iMAC2 Controller, 2-wire and 3-wire iMAC systems remain unchanged.
