EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
The detector is a hand held device used to detect hydrogen leaks and is powered by a rechargeable Lithium
ion battery. The device consists of a main unit interconnected by a pluggable cable to a PX50 series probe
unit.
The housing of the main unit is made from aluminium which is anodized and protected by conductive rubber
face seals fitted to the front and rear panels. The side panels and corners of the enclosure are fitted with
protective rubber ribs. The back panel has a Gortex seal and a socket intended to be used outside hazardous
areas, for connecting to the battery charger/barcode reader. The battery charger has the following maximum
parameters, 12.6 V, 770 mA.
The probe has a conductive plastic enclosure and a nozzle which varies in length and type. Inside the nozzle
fits a hydrogen sensor (Ex component according to ExTR SE/SP/ExTR07.0001/00 and ATEX certificate
SP07ATEX3636U). The probe is fully encapsulated, however, a switch, two LEDs and the hydrogen sensor
are located outside the encapsulation.
The detector has an ingress protection rating of IP67.
CONDITIONS OF CERTIFICATION: YES as shown below:
Conditions of Certificate and Manufacture
The applicant (manufacturer) shall note the following:
1. The permitted battery pack is constructed from 3 series connected SAFT type MP174865IS or type
MP174865 Lithium ion rechargeable cells all encapsulated in Wacker Elastosil RT675.
2. The products covered by this certificate incorporate previously certified devices, it is therefore the
responsibility of the manufacturer to continually monitor the status of the certification associated with these
devices, and the manufacturer shall inform SP of any modifications of the devices that may impinge upon the
explosion safety design of their products.
3. The IECEx certificate number referred to in the Manufacturer´s Documents and in the Marking Plate,
according to ExTR GB/SIR/ExTR07.0085/00, shall be "IECEx SP 07.0002X".
.
Conditions for Safe Use
As aluminium is used at the accessible surface of this equipment, in the event of rare incidents, ignition
sources due to impact and friction sparks could occur. This shall be considered when the detector is being
installed or used in locations that specifically require level of protection Ga (see IEC 60079-26).
