Feedthrough Accessory Installation: When ordered with a case style B bearing sensors, spring and ring are automatically included.
-
See page 2 of model specification drawing for accessory assembly features.
-
Installation of Temperature Detectors shall be carried out only by persons whose training has included instruction on the various types of protection and installation practices, relevant rules and regulations and on the general principles of area classification. The competency of the person shall be relevant to the type of work to be undertaken.
Special Conditions for Safe Use
The equipment is Intrinsic Safety and Increased Safety rated, and can be used
in potentially explosive atmospheres.
Because of the 3 protection modes available, the user must check the
appropriate box on the marking label (See §8. Marking Examples.)
All Installations:
The electrical parameters of the associated equipment must not exceed any of
the following values:
Uo ≤ 30 V, Io ≤ 46 mA and Po ≤ 0.4 W.
For North America, power supplied to this equipment shall be from a source
considered “Class 2”, per the Canadian Electrical Code Part I, C22.1, Section
16-200, and the National Electrical Code, NFPA 70, Article 725.121. Connect
using National Electrical Code, NFPA 70, Articles 504 and 505, and Canadian
Electrical Code Part I, C22.1, Section 18.
After installation, the user shall ensure that the ambient temperature is
respected for the apparatus and connected equipment. It shall be suitable for
the measured service temperature with the temperature sensor installed.
Intrinsic Safety Installations only:
The apparatus must be only connected to certified associated intrinsic safety
equipment and this combination must be compatible as regards to intrinsic
safety rules.
The electrical parameters of the associated intrinsic safety equipment must
not exceed any of the following values:
Uo (or Voc) ≤ 30 V and Po ≤ 0.4 W.
The connection of the cable must be effected in an enclosure with a minimum
protection degree IP20 according to clause 6.1 of the standard EN 60079-11.
After integration in the end-use system, the apparatus shall be submitted to a
dielectric test of 500VAC, 50/60HZ during 60 Seconds without breakdown at 5 mA
RMS, according to Clause 10.3 of CAN/CSA C22.2 No. 60079-11:14, ANSI/UL
60079-11-2014, and IECEx/EN 60079-11(not applicable for grounded junction
thermocouples).
Increased Safety Installations only:
This device is OPEN type equipment that must be used within a suitable end-use
system enclosure, the interior of which is accessible only through the use of
a tool.
Flying leads must be terminated within a suitable enclosure having a screw or
spring terminal suitable for use with 24 AWG (0.25 mm2 ) or smaller conductors
which are appropriately rated for the service temperature, maintain the
required spacings, (Creepage: 1.8 mm “eb” and 1.3 mm “ec”; Clearance: 1.8 mm
“eb” and 0.8 mm “ec”); and secures against accidental disconnection.
This device must be installed in an appropriately certified (e.g. Ex p, Ex d,
Ex e, Ex nA or equivalent protection concept) enclosure, which provides a
minimum ingress protection of IP54 and protects against mechanical impact.
After integration in the end-use system, the apparatus shall be submitted to a
dielectric test of 500VAC, 50/60HZ during 60 Seconds without breakdown at 5 mA
RMS, according to Clause 7.1 of CAN/CSA C22.2 No. 60079-7:15, ANSI/UL
60079-7-2017, and IECEx/EN 60079-7 (not applicable for grounded junction
thermocouples).
Entity Parameters and Electrical Data
The following applies to all protection modes:
| S models| TC models
---|---|---
Maximum input voltage Ui (or Vmax)| 30 V| 30 V
Maximum input power Pi (or Pmax)| 0.40 W| n/a
Maximum input current Ii (or Imax)| 46 mA| 46 mA
For intrinsic safety: Cable: Ci_max = 0.028ŋF/m Li_max = 0.0013mH/m Ri_max = 0.16 Ω/m
Temperature Class Tables
For installation, the user shall ensure that the ambient temperature of
connective parts is respected. It shall not be impacted by the measured
temperature.
The temperature class rating of the equipment is determined according to the
ambient temperature (process side) and the dissipated power in the sensor.
Power dissipated in the S __**(RTD) sensor| Maximum

Class T6| Class T5| Class T4| Class T3**| Class T2
0.1 W| +70°C| 85°C| 120°C| 185°C| 200°C
0.2 W| +65°C| 80°C| 115°C| 180°C| 200°C
0.4 W| +50°C| 65°C| 100°C| 165°C| 200°C

Class T6| Class T5| Class T4| Class T3**| Class T2
0.1 W| +70°C| 85°C| 120°C| 185°C| 200°C
** Elastomer-filled cables should not be used for T3 temperature class
applications. Feedthroughs should not be used on T3 temperature class
applications where ambient temperature exceeds +85°C (or +135°C on special
orders).
*** Elastomer-filled cables and feedthroughs should not be used on T2
temperature class applications.
