Basic safety instructions iTHERM TMS11 MultiSens Linear

2 Basic safety instructions

Instructions and procedures in the operating instructions may require special precautions to ensure the safety of the personnel performing the operations. Information that potentially raises safety issues is indicated by safety pictograms and symbols. Please refer to the safety messages before performing an operation preceded by pictograms and symbols. Although the information provided herein is believed to be accurate, be advised that the information contained herein is NOT a guarantee of satisfactory results. Specifically, this information is neither a warranty nor guarantee, expressed or implied, regarding performance. Please note that the manufacturer reserves the right to change and / or improve the product design and specifications without notice.

2.1 Requirements for the personnel

The personnel for installation, commissioning, diagnostics and maintenance must fulfill the following requirements:

Trained, qualified specialists must have a relevant qualification for this specific function

‣

and task Are authorized by the plant owner/operator

‣

Are familiar with federal/national regulations

‣

Before beginning work, the specialist staff must have read and understood the

‣

instructions in the Operating Instructions and supplementary documentation as well as in the certificates (depending on the application) Following instructions and basic conditions

‣

The operating personnel must fulfill the following requirements:

Being instructed and authorized according to the requirements of the task by the

‣

facility's owner-operator Following the instructions in these Operating Instructions

‣

2.2 Designated use

The product is intended to measure the temperature profile inside a reactor, vessel or pipe through RTD or thermocouple technologies.

The manufacturer is not liable for damage caused by improper or non-designated use.

The product has been designed according to the following conditions:

Condition Description

Internal pressure The design of joints, threaded connections and sealing elements has been

executed as a function of the maximum allowable pressure inside the reactor.

Operating temperature The materials used were chosen according to the operating and design

minimum and maximum temperatures. Thermal displacement has been taken into account to avoid intrinsic stresses and to ensure proper integration between the instrument and the plant. Specific care has to be taken when the instrument is fixed to the plant internals.

Process fluids Dimensions and choice of materials minimize:

• distributed and localized corrosion,

• erosion and abrasion,

• corrosion phenomena due to uncontrolled and unpredictable chemical reactions.

Specific process fluids analysis is necessary to properly ensure the maximum operating life of the device, through proper material selection.

Fatigue Cyclic loads during operations are not foreseen.

6 Endress+Hauser

iTHERM TMS11 MultiSens Linear Basic safety instructions

Condition Description

Vibrations The primary thermowell and sensing elements can be subjected to vibrations,

due to high immersion lengths from the constraint located in the process connections. This vibrations can be minimized by properly selecting the product configuration of the temperature assembly. The extension neck has been designed for withstanding vibratory loads to preserve the junction box from cyclic loading, and to avoid the unscrewing of the threaded components.

Mechanical stress The maximum stress on the measuring device multiplied by a safety factor is

guaranteed to stay below the yielding stress of the material, for every working condition of the plant.

External environment The junction box (with and without head transmitters), wires, cable glands and

other fittings have been selected to work within the allowed ranges in terms of external temperature.

2.3 Workplace safety

The external installation area must be free of interferences to avoid any injury during installation, and to avoid any damage to the measuring device.

2.4 Operational safety

Operate the device in proper technical condition and fail-safe condition only.

‣

The operator is responsible for interference-free operation of the device.

‣

Hazardous area

To eliminate a danger for persons or for the facility when the device is used in the hazardous area (e.g. explosion protection or safety equipment):

Based on the technical data on the nameplate, check whether the ordered device is

‣

permitted for the intended use in the hazardous area. The nameplate can be found on the side of the junction box. Observe the specifications in the separate supplementary documentation that is an

‣

integral part of these Instructions.

Electromagnetic compatibility

The measuring system complies with the general safety requirements in accordance with EN 61010-1, the EMC requirements of IEC/EN 61326 and NAMUR Recommendation NE 21 and NE 89.

NOTICE

The unit must only be powered by a power supply that operates using an energy-

‣

limited electric circuit that is compliant with IEC 61010-1, "SELV or Class 2 circuit".

2.5 Product safety

The unit is constructed using the most up-to-date production equipment and complies with the safety requirements of the local guidelines. The temperature measuring system is fully factory tested according to the specifications indicated on the order and/or any additional test which is considered as safety-relevant. However, if it is installed incorrectly or is misused, certain application dangers can occur. Installation, wiring and maintenance of the unit must only be done by trained, skilled personnel who are authorized to do so by the plant operator. This skilled staff must have read and understood these instructions and must follow them. The plant operator must make sure that the measurement system has been installed by tightening the threaded components (e.g bolts and nuts) with the predefined torques and tools , and correctly wired according to the wiring diagrams.

Product description iTHERM TMS11 MultiSens Linear

3 Product description

3.1 Equipment architecture

The multipoint thermometer belongs to a range of modular product configuration for multipoint temperature detection with a design where subassemblies and components can be managed individually for easy maintenance and spare part ordering.

It consists of the following main sub-assemblies:

• Insert: Composed by individual metal sheathed sensing elements (thermocouples or thermos-resistance) protected by the primary thermowell welded to the process connection. In addition, individual guiding tubes or protecting themowells allow inserts replacement during operating conditions. When applicable, each insert can be handled as an individual spare part and ordered via specific standard product order codes (e.g. TSC310, TST310) or special codes. For the specific order code please contact your Endress+Hauser specialist.

• Process Connection: Represented by an ASME or EN flange. It can be provided with pressure port and it might be provided with eyebolts for lifting the device.

• Head: It is composed of a junction box provided with its components such as cable glands, draining valves, earth screws, terminals, head transmitters, etc.

• Head Support Frame: It is designed to support the junction box. Two different types are available:

• Direct mounted support frame

• Three pieces union joint

• Additional Accessories: They can be ordered for any configuration, and they are recommended in case of replaceable sensors configuration (such as pressure transducers, manifolds, valves and fitting).

• Primary Thermowell: It is directly welded to the process connection, designed to guarantee high degree of mechanical protection and corrosion resistance.
