2.5.1
For SITRANS TS500
● The enclosures types AG0, AH0, AU0, AV0 and SITRANS TF of the temperature
sensors, series TS500 have to be connected by means of suitable cable entry fittings or
conduit systems, which meet the requirements of IEC/EN 60079-1, sections 13.1 and
13.2, and for which a separate examination certificate has been issued.
● Cable entry fittings (conduit threads) and sealing plugs of simple design must not be used
in the transmitter and receiver enclosures.
● Any openings in the transmitter and receiver enclosures that are not used must be closed
as specified in IEC/EN 60079-1, section 11.9.
● The connecting lead of enclosures types AG0, AH0, AU0, AV0 and SITRANS TF of the
temperature sensors, series TS500, must be installed to provide for permanent wiring
and adequate protection against damage.
● If the temperature at entry fittings should exceed 60 °C, the connecting cables used have
to be of the temperature-resistant type.
● If connection is made in the potentially explosive area, the connecting cable
(unconnected cable end) of the enclosure types AG0, AH0, AU0, AV0 and TF of the
temperature sensors, series TS500, must be connected in an enclosure that meets the
requirements of an approved type of protection as specified in IEC/EN 60079-0, section
1.
● All models are to be mounted within Thermowells suitably rated for the application they
are used.
● If a SITRANS TS500 with XP type of protection is combined with a thermowell, consider
the ASME PTC19.3 and a minimum wall thickness of 1 mm.
● To separate zone 1 from zone 2 in a hazardous area, consider a wall thickness of ≥ 1 mm
with austenitic steel. In addition, consider the existing process conditions.
If a thermowell installed correctly and tight at Zone 0, the sensor that is screwed in this
thermowell needs at least zone 1 approval.
● Suitably rated Thermowells are to have thread engagement of 5 full turns wrench tight.
● Notes to this effect must accompany each device in an adequate form.
● Components attached or installed (terminal compartments, bushings, cable entry fittings,
connectors) must be of a technical standard that complies with the specifications on the
Certificate of Conformity as a minimum, and a separate examination certificate must have
been issued for them.
● Use the device to measure temperature in accordance with the technical data for
maximum permitted ambient temperatures in the connection area of the sensor. See
chapter Gas hazardous area: Ex d / XP (Page 52) and Dust hazardous area: Ex i / IS / Ex
tb / DIP (Page 53).
