Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 
The AZ30 Oxygen Probe comprises a stainless steel tubular assembly of varying lengths intended to be inserted between 0.5m and 2.0m into a flue or similar detection zone. A mounting flange is welded to the probe tube. At the inserted end of the probe tube is a stainless steel sinter assembly to permit the ingress of the sample gas to the detection cell. 

At the protruding end is a cylindrical terminal/control housing with a threaded cover containing terminals together and optional flow control devices together with associated pipework for calibration and reference gas/air supplies.  The reference gas/air supplies optionally enter the enclosure via ports fitted with sintered metal elements at the rear of the terminal enclosure.

A cable entry boss is provided on the side of the enclosure to facilitate the connection of suitably certified cable entry devices via an insert threaded M20 or M25, or alternatively 1/2 NPT or 3/4 NPT.

Cable entry holes are provided as specified on the certified drawings for the accommodation of flameproof cable entry devices, with or without the interposition of a flameproof thread adapter. Unused entries are to be fitted with certified flameproof stopping plugs.

The cable entry devices, thread adapters and stopping plugs shall be suitable for the equipment, the cable and the conditions of use and shall be certified as Ex Equipment and not an Ex Component.

 

 
CONDITIONS OF CERTIFICATION: YES as shown below:
 
1.  This apparatus is intended for use in atmospheres at, or below, normal pressures and oxygen levels, i.e. no greater than 1.1 bar and 21% respectively.

2.  Some flamepath gaps are specified tighter than those permitted by Table 2 of IEC 60079-1. The manufacturers instructions are to be consulted for information on these dimensions if required for inspection and/or maintenance

3.  For replacement purposes the fasteners are to be stainless steel grade A2/A4-70 or stronger

4.  When used in dust atmospheres the cable entries shall be sealed in accordance with IEC 60079-14 to maintain the IP66 rating
