1 Introduction

In accordance with Directive RL 94/9/EC (ATEX

95) Annex I, the InPro

®

7100 i/12/***/**** con-

ductivity sensor is classied in Device Group II

Category 1/2 G, which according to Directive

RL99/92/EC (ATEX 137) may be used in zones

0/1 or 0/2 or 1 or 2 as well as gas groups IIA and

IIB, which have potentially explosive atmospheres

due to combustible materials in the range of tem-

perature classes T1 to T6.

It must be installed and used in compliance with

the requirements of EN 60079-14.

The ISM measurement circuit is part of a common

intrinsically safe system and is connected to and

operated with a separately certied transmitter.

As part of an intrinsically safe system, the ISM

®

measurement circuit has safe galvanic isolation

at the transmitter from circuits that are not intrin-

sically safe up to the peak value of a nominal

voltage of 375 V and from earthed parts up to the

peak value of a nominal voltage of 30 V.

3.2 The permissible external ambient temperature

range in the area of the connector head is – 20 °C

to + 50 °C.

3.3 The conductivity sensor InPro 7100 i/12/***/****

must only be used in suitable process connectors

of METTLER TOLEDO or other manufacturers in

potentially explosive areas.

3.4 The capacitance and inductance of the connect-

ing cable must be taken into account in the di-

mensioning.

3.5 In areas with potentially explosive atmospheres,

InPro 7100 i/12/***/**** conductivity sensor

can be used in / with the InFit

®

76*-*** or

InTrac

®

7**-*** ttings or in / with other suitable

ttings.

If necessary, this tting must be included in the

periodic pressure testing of the system or facility.

3.6 The independent process tting used for the in-

stallation of the conductivity sensor must be elec-

trically connected to the potential equalization

system of the system or facility, and if necessary

it must be included in the periodic pressure testing

of the system or facility.

3.7 To ensure safe working conditions in areas with

potentially explosive atmospheres, the minimum

conductivity of the media must always be greater

than 1 nS / cm.

InPro, InFit, InTrac and ISM are registered trade-

marks of Mettler-Toledo GmbH in Switzerland,

USA, European Union and a further ve countries.
