6.4 Shielding and grounding

For any specific electrical shielding and grounding regarding the transmitter wiring please refer to the appropriate operating manual of the installed transmitter.

Where applicable, national installation regulations and guidelines must be observed during the installation! Where there are large differences in potential between the individual grounding points, only one point of the shielding is connected directly with the reference ground. In systems without potential equalization, therefore, cable shielding of fieldbus systems should only be grounded on one side, for example at the supply unit or at safety barriers.

NOTICE

If the shielding of the cable is grounded at more than one point in systems without potential matching, power supply frequency equalizing currents can occur that damage the signal cable or have a serious effect on signal transmission.

In such cases the shielding of the signal cable is to be grounded on only one side, i.e. it

‣

must not be connected to the ground terminal of the housing (terminal head, field housing). The shield that is not connected should be insulated!

6.5 Degree of protection

The device is conform to the requirements up to IP 66 ingress protection. In order to fulfil the degree of protection after installation or service, the following points must be taken into consideration: →  8,  22

Endress+Hauser 21

Wiring iTHERM TMS11 MultiSens Linear

• The housing seals must be clean and undamaged before they are replaced in the sealing rebate. If they are found to be too dry, they should be cleaned or even replaced.

• All housing screws and covers must be tightened.

• The cables used for connection must be of the correct specified outside diameter (e.g. M20 x 1.5, cable diameter from 0.315 to 0.47 in; 8 to 12 mm).

• Tighten cable gland.

• Loop the cable or conduit before placing into the entry ("Water sack"). This means that any moisture that may form cannot enter the gland. Install the device so that the cable or conduit entries are not facing upwards.

• Entries not used are to be blanked off using the blanking plates provided.

• The protective grommet must not be removed from the NPT fitting.

iTHERM TMS11 MultiSens Linear Technical data

Calibration Calibration is a service that can be performed on each individual insert, either in order

phase, or after multipoint installation (only in case of replaceable sensors).

When calibration shall be performed once the multipoint is installed, please contact the Endress+Hauser service to get full support. Together with the Endress +Hauser service any further activity can be organised to achieve the calibration of the target sensor. In any case it is forbidden to unscrew any threaded component on the process connection under operating conditions (running process), without knowing the pressure inside the primary thermowell.

Calibration involves comparing the measured values of the sensing elements of the multipoint inserts (DUT device under test) with those of a more precise calibration standard using a defined and reproducible measurement method. The aim is to determine the deviation of the DUT measured values from the true value of the measured variable.

Two different methods are used for the inserts:

• Calibration at fixed-point temperatures, e.g. at the freezing point of water at 0 °C (32 °F).

• Calibration compared against a precise reference thermometer.

Evaluation of inserts

If a calibration with an acceptable uncertainty of measurement and transferable measurement results is not possible, Endress+Hauser offers an insert evaluation measurement service, if technically feasible.

11.5 Mechanical construction

Design, dimensions The overall multipoint assembly is composed of different sub-assemblies. Different inserts

are available, based upon specific process conditions, in order to have the highest accuracy and an extended lifetime. The primary thermowell should be selected to increase mechanical performances and corrosion resistance. Associated shielded extension cables are available with high resistance sheath materials to withstand different environmental conditions and to ensure steady and noiseless signals. The transition between the inserts and the extension cable is obtained by the usage of specially sealed bushings, ensuring the declared IP degree protection.

Support system

A modular system or a union joint is foreseen in case of direct mounted junction box.

It ensures the connection between the head of the primary thermowell and the junction box. The system design ensures easy access for monitoring and maintaining inserts and extension cables. Rods and protection cover guarantee a high stiffness connection for the junction box and vibration loads. No closed volumes are present in the frame design although it allows protection to the cables. This avoids the accumulation of waste and potentially dangerous fluids coming from the environment that can damage the instrumentation allowing continuous ventilation.

In case of three pieces union joint design the junction box can be orientated and the extension cables remain accessible thanks to the disassembling of the joint.

Diagnostic function

The reactors where the multipoint assembly operates are usually characterized by severe conditions in terms of pressure, temperature, corrosion and dynamics of the process fluids. Thanks to the pressure port, it is possible to detect and monitor possible leakages (or gases permeation) occurring through the primary thermowell, and plan the maintenance.

Weight The weight can vary based upon the configuration, depending on the junction box and the

frame design. The approximate weight of a typically configured multipoint thermometer (number of inserts = 12, main body = 3", medium size junction box) = 30 kg (66.1 lb).
