2. Design and function
2.1 Description
The model TR10-0 (resistance thermometer) or TC10-0 (thermocouple) electrical
thermometers are comprised of a measuring insert which is built into a certied case. In
combination with a ame path tting that is screwed into the head, the measuring insert
functions as a ameproof joint. The measuring insert (TR10-1, TC10-1) is replaceable.
Sensor design in model TR10-0
The measuring resistor is embedded in ceramic powder, heat-resistant potting compound,
cement compound or thermally conductive paste. A welded cap forms the external shell of
the sensor tip of the measuring insert.

Sensor design in model TC10-0
The measuring insert of the thermocouple is manufactured from mineral-insulated cable.
The thermocouple consists of the internal leads of the mineral-insulated cable.The weld
spot of the thermocouple is, depending on the design, either ungrounded welded with the
internal leads of the mineral-insulated cable or grounded welded.
If the temperature sensor is designed as a grounded thermocouple, the thermocouple is
joined directly to the sheath. Designs with a diameter smaller than 3 mm and with grounded
thermocouples should be considered as galvanically connected with earth potential.
Available versions:
■
Flame path without thermowell
■
Flame path with thermowell
■
Thermometers without a ame path tting may be designed as a welded bushing without
thermowell
Thermometers without a ame path tting may only be used in combination with a solid-
machined, certied WIKA thermowell with a minimal wall thickness of 1 mm.
After installation of a ame path tting into the connection head of the thermometer, a
thermowell is no longer mandatory for certication reasons. In most cases, however, the
use of a thermowell (with a wall thickness of 1 mm) is necessary for process engineering
reasons.
The design of the thermowell can be selected as desired, but the operational process
data (temperature, pressure, density and ow rate) must be taken into account. If a WIKA
thermowell is already available or installed, a ame path tting is not necessary.
The thermometers models TR10-0 or TC10-0 are manufactured by WIKA with certied
connection heads or connection housings.These enclosures and covers are made from
aluminium or stainless steel.The cover is optionally available with a glass window.
Possible sensor measuring ranges see chapter 11 “Specications”
The following mounting and operating information has been compiled with care.
However, it is not possible to consider all potential usage cases.

6. Information on mounting and operation in hazardous areas
WARNING!
Non-observance of these instructions and their contents may result in the loss
of explosion protection.
The requirements of CSA and FM must be followed. Additionally the
specications of the respective national regulations concerning usage (e.g.
CEC and NEC) apply.
■
The responsibility for area classication lies with the plant operator and not the
manufacturer/supplier of the equipment.
■
The plant operator guarantees, and is solely responsible, that all thermometers in use
are identiable with respect to all safety-relevant characteristics. Damaged thermometers
may not be used.
■
For the installation of the thermometer, only components (e.g. cables, cable glands, etc.)
permitted for “ameproof” may be used.
■
For earthing the conductive screen, follow the specications of CEC or NEC.
■
When using a transmitter/digital display, note and follow:
- The contents of these operating instructions and those of the transmitter/digital display
- The relevant regulations for installation and use of electrical systems
- The regulation and guidelines regarding explosion protection
■
The ameproof thermometers should only be tted to certied enclosure or connection
heads certied with a “ameproof” ignition protection type.
■
For tting, the permitted ameproof joints for electrical equipment for gas hazardous
areas are contained in CSA C22.2 No. 30, CSA 60079-1 and FM 3615.
■
The direct threaded connection of the thermometer to the connection head or enclosure
must not be twisted or opened. Any alignment of the enclosure may only be made using
the optional “nipple-union-nipple” neck tube.
■
The temperature resistance of the connection cable must match the permissible
operating temperature of the enclosure. For ambient temperatures above 60 °C [140 °F],

■
No batteries may be built in to the ameproof enclosure.
■
No capacitor may be tted within the ameproof enclosure.The enclosure must not be
opened during operation. After the supply voltage has been switched o, a waiting time of
2 minutes must be observed before the enclosure is opened.
■
Mounting within metal enclosures:
The enclosure must be grounded against electromagnetic elds and electrostatic
discharge. It does not have to be connected separately to the equipotential bonding
system. It is sucient if the metal thermowell has a solid and secured contact with the
metal vessel or its structural components or pipelines, so long as these components are
connected to the equipotential bonding system.

Temperature class classication, ambient temperatures
A heating in the connection head can occur with built-in transmitter through faulty
electronics.The permissible ambient temperatures depend on the cases used and any
additionally tted head-mounted transmitter.
For all WIKA connection heads with built-in WIKA temperature transmitters, the
following interrelation is valid:
The temperature increase on the surface of the connection head or case is less than 25 K
if the following conditions are observed: supply voltage UBmaximum DC 30 V when the
transmitter is operated in a current limit of 22.5 mA.
The temperature class is dependent upon the user application and the ambient temperature.
The permissible ambient temperatures for third-party products can be seen from the relevant
approvals and/or data sheets. However, an impermissible heat reux from the process
which can exceed the operating temperature of the case or the temperature class, must be
prevented through suitable heat insulation or a suitably long neck tube.

For contact details, please see chapter 1 “General information” or the back
page of the operating instructions.
9.1 Maintenance
The thermometers described here are maintenance-free.
Repairs must only be carried out by the manufacturer.
9.2 Cleaning
CAUTION!
Physical injuries and damage to property and the environment
Improper cleaning may lead to physical injuries and damage to property and
the environment. Residual media in the dismounted instrument can result in a
risk to persons, the environment and equipment.
▶Carry out the cleaning process as described below.
1. Prior to cleaning the electrical connections, disconnect them properly.
2. Clean the instrument with a moist cloth.
3. Electrical connections must not come into contact with moisture.
CAUTION!
Damage to the instrument
Improper cleaning may lead to damage to the instrument!
▶Do not use any aggressive cleaning agents.
▶Do not use any pointed and hard objects for cleaning.
4. Wash or clean the dismounted instrument, in order to protect persons and the environ-
ment from exposure to residual media.
Residual media in the dismounted instrument can result in a risk to persons, the environ-
ment and equipment. Take sucient precautionary measures.
9.3 Calibration, recalibration
It is recommended that the measuring insert is recalibrated at regular intervals (resistance
thermometers: approx. 24 months, thermocouples: approx. 12 months). This period can
reduce, depending on the particular application.The calibration can be carried out by the
manufacturer, as well as on-site by qualied technical sta with calibration instruments.
For calibration, the measuring insert is removed from the thermometer. The minimum length
(metal part of the probe) for carrying out a measurement accuracy test 3.1 or DAkkS is
100 mm [3.94 in].
Calibration of shorter lengths on request.

10.Dismounting, return and disposal
10.1 Dismounting
WARNING!
Physical injuries and damage to property and the environment through
residual media
Upon contact with hazardous media (e.g. oxygen, acetylene, ammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
▶Before storage of the dismounted instrument (following use) wash or
clean it, in order to protect persons and the environment from exposure to
residual media.
▶Use the required protective equipment (depending on the application; the
thermometer itself is basically not dangerous).
▶Observe the information in the material safety data sheet for the
corresponding medium.
Only disconnect the thermometer once the system has been depressurised.
WARNING!
Risk of burns
During dismounting there is a risk of dangerously hot media escaping.
▶Let the instrument cool down suciently before dismounting it!
