carrier materials.
Table 7- 53
Carrier material
Transponder on wooden carrier
(dry, degree of moisture < 15%)
Transponder on plastic carrier
Transponder on glass
The maximum range of 100% is achieved by mounting the transponder in a free space with
low reflections on a flat metal carrier with a diameter of at least 300 mm.
You will find further information on the range in the section "Minimum distances and
maximum ranges (Page 293)".
7.14.3.4 Use of the transponder in hazardous areas
TÜV NORD CERT GmbH, appointed center no. 0044 as per Article 9 of the Directive
94/9/EC of the European Council of 23 March 1994, has confirmed the compliance with the
essential health and safety requirements relating to the design and construction of
equipment and protective systems intended for use in hazardous areas as per Annex II of
the Directive.
The essential health and safety requirements are satisfied in accordance with standards
IEC 60079-0:2011 and EN 60079-11:2012.
This allows the RF680T transponder to be used in hazardous areas for gases, for the device
category 2G and gas group IIB, or alternatively in hazardous areas for dusts, for the device
category 2D and group IIIB.
Note
Readability of the serial number on the type plate
When using the transponder, make sure that the serial number can be read. The serial
number is lasered and can be hidden by paint or other materials making it illegible.
The customer is responsible for making sure that the serial number of a transponder for the
hazardous area can be read at all times.
