TMT142C

Function and system design

Measuring principle In the thermocouple thermometer the sensing element is created by the physical junction of two homogeneous

but different alloys (wires) isolated for the entire length, except in the junction point. The two wires are welded
on one side, named ‘measuring or hot junction’, while the free wires side, named ‘reference or cold junction’
is connected to an electrical circuit measuring the electromotive force (mVolts) generated by the different
thermoelectric characteristics of the two thermocouple wires when a temperature difference between the hot
junction (T1) and the cold junction (T0) occurs. The function linking the electromotive force to the
temperatures T1 and T0 depends on the materials utilized in the alloys. These functions are standardized
curves, for different alloys couples, by the following international standards: IEC 60584 and ANSI MC96.1.

HART Communication

Example of an application of the compact thermometer

The Omnigrad S HART® TMT142C is a compact thermometer with a two-wire transmitter and an input for
thermocouples (Type J or K) and an analog output. The LC display shows the current measured value digitally
and as a bar graph with an indicator for limit value violation. The TMT142C can be operated via the HART
protocol using a handheld terminal (DXR375) or PC (FieldCare or ReadWin

®

2000 operating software).
The sensor construction is based on the IEC 60751 standard, giving high reliability and performance in all the
typical industrial environment conditions.
The TC sensing elements are created by two types of alloy couples: the type J (Fe-CuNi) or the type K (NiCr­Ni). The measuring ranges of this temperature sensing elements have different values depending on the couple
types. The measuring probe (TC replaceable insert) is installed in a suitable thermowell.
Thanks to the spring load construction method, the thermometer insert stays always in contact with the inner
tip of the thermowell in order to guarantee the best heating transfer from the process to the sensing element.
The transmitter housing is available either in coated aluminum or stainless steel (optional), with or without LC
display. The fit between housing, thermowell and cable gland ensures a minimum IP65 (Ingress Protection)
grade.
The thermowell can be either welded or made from bar-stock material. The thermowells are available in
different forms and with many process connections: threads, flanges or weld-in types (see the paragraph
“Thermowell”).

Corrosion detection

Sensor connection line corrosion can corrupt the measured value. For this reason, the device gives you the
opportunity to detect corrosion for thermocouples and resistance thermometers with a 4-wire connection
before measured value corruption takes place.

Mechanical construction

Installation The Omnigrad S resistance thermometer model TMT142C can be mounted on the wall of pipes or vessels or

other plant parts. In the case of ATEX/FM/CSA certified components (transmitter + insert), please refer to the
relevant documentation (see "Documentation").
The immersion length may have an effect on the accuracy of the measurement. If the immersion is too small,
an error may be generated in the temperature detected due to the lower temperature of the process fluid near
to the walls and the heat transfer, which takes place through the sensor shaft. The incidence of such an error
is not negligible if there is a big difference between the process temperature and the ambient temperature. In
order to avoid this source of inaccuracy,the thermowell should have a small diameter and the immersion length
(L) should be, if possible,at least 100-150 mm.
In pipes of a small cross-section the axis line of the duct must be reached and if possible slightly exceeded by
the tip of the thermowell (refer to fig. A and C). Another solution may be a tilted installation (see fig. Band D).

Examples of installation

In the case of two-phase flows, please pay special attention to the choice of the measurement point, as there
may be fluctuations in the value of the detected temperature. With regard to corrosion, the base material of the
wetted thermowells is important.
In case that the sensor components are disassembled and than re-mounted the proper assembling torque must
be applied in order to guarantee the defined ingress protection.

Housing The housing of the TMT142C is a single compartment container.

Microcontroller controlled display in single chamber housing with illuminated LC display. Parameterization of
measuring range, decimal point and offset of the display can be done comfortably using a PC with the PC
software ReadWin
for power supply.

Extension neck The function of the extension neck between the sensor and the transmitter (electronic with display) is to

protect the transmitter from overheating due to high process temperatures.
The extension neck consists of various couplings (nipples, union) suitable to adapt the temperature sensor to
the different thermowells.
The neck material is usually stainless steel 316L/1.4404.
The standard lengths (N) and the extension neck versions are selectable amongst the following options:

• 52 mm (2.05") (only 1/2” NPT, Type L)

• 102 mm (4.02") (nipple+union, Type LU)

• 96 mm (3.78") (nipple+coupling, Type LC)

• 144 mm (5.67") (nipple+union+nipple, Type LUN)

• 138 mm (5.43") (nipple+coupling+nipple, Type LCN)

Besides the standard neck options indicated it is possible to order a specific neck by entering the length in the
order code.
The mechanical coupling situated in the upper part of the neck allows for orientation of the sensor head. As
illustrated by the figure below, the length of the extension neck influences the temperature in the head. The
extension neck length has to be chosen in such a way that the temperature within the head remains below the
maximum permissible operating temperature.

Thermowell The thermowell already exists in the plant or has to be ordered separately. To this end the extension neck is

available with different forms.In order to easily select the right mechanical fitting for the thermowell you are
kindly requested touse the table list and the ML values described at the chapter “Probe”.

Probe In the TMT142C compact thermometer the probe consists of a mineral oxyde insert which is inserted and fixed

into the thermowell.
The length of the sensor is freely selectable inside the predefined lengths range (50 to 990 mm / 1.97" to 39").
Sensors exceeding the 990 mm (39") length are available on request.
The immersion length (ML) must be defined as a function of the type and length of the relevant thermowell.
In case of spare inserts to be ordered please read carefully the following table (table valid for standard thickness
