Range of application

The BM 102 MICROFLEX level gauge is designed solely for measuring the distance, level and volume of liquids, solids and particulate materials. The device can be operated on storage and process tanks and also on still pipes and reference vessels.

Product liability and warranty

Responsibility for suitability and intended use of these level gauges rests solely with the user.

Improper installation and operation of our devices may lead to loss of warranty.

In addition, the “General conditions of sale“, forming the basis of the purchasing contract, are applicable.

Supplementary Installation and Operating Instructions BM 102 ATEX

General safety information

These Supplementary Instructions may only be used in conjunction with the standard Installation and Operating Instructions for the BM 102 level gauge. If you do not have these standard Instructions, please contact your nearest KROHNE office.

Special regulations are applicable to the use of equipment in hazardous locations, and these are described in these Supplementary Instructions (supplied only with “Ex” devices).

The information given in these Instructions contains only the data relevant to explosion protection. The technical details given in the standard Installation and Operating Instructions apply unchanged unless excluded or superseded by these Supplementary Instructions.

Standards / Approvals

In compliance with European Directive 94/9 EC (ATEX 100a), the level gauges described in these Supplementary Instructions are, in conformity with European Standards EN 50014, EN 50020 and EN 50284, certified for use in hazardous locations by the KEMA certification body under KEMA 00 ATEX 1101 X.

It is absolutely necessary that the details contained in this approval certificate, together with its boundary conditions, are observed.

The level gauges of the BM 102 series are suitable for use in explosive atmospheres of all flammable substances of Gas Groups IIA, IIB und IIC (with the exception of the cases named in these Supplementary Instructions) and for applications requiring Category 1G, 1/2G, 1/2D, 2G or 2D equipment.

Assembly, installation, start-up and maintenance may only be carried out by "personnel trained in explosion protection"!

Supplementary Installation and Operating Instructions BM 102 ATEX

1 Main safety-relevant characteristics

1.1Approved categories

Plastic-coated probes may not be used in connection with Gas Group IIC substances.

1.1.1 1 G

The BM 102 level gauges are installed in areas requiring Category 1 G equipment. The devices are suitable for use in explosive atmospheres of all flammable substances of Gas Groups IIA, IIB and IIC.

1.1.2 1/2 G and 1/2 D

The signal converter is installed in hazardous locations requiring Category 2 G or 2 D equipment. The probe is installed in hazardous locations requiring Category 1 G or 1 D equipment. The devices are suitable for use in explosive atmospheres of all flammable substances of Gas Groups IIA, IIB and IIC.

Devices with plastic-coated probes may not be used for applications requiring Category 1/2 D equipment, unless effective measures have been taken to avoid electrostatic discharge.

1.1.3 2 G and 2 D

BM 102 devices are installed in locations requiring Category 2 G or 2 D equipment. The devices are suitable for use in explosive atmospheres of all flammable substances of Gas Groups IIA, IIB and IIC.

Devices with plastic-coated probes may not be used for applications requiring Category 2 D equipment, unless effective measures have been taken to avoid electrostatic discharge.

1.2Maximum safety-relevant values

The input terminals of the BM 102 level gauges are not safety-separated from ground. For that reason, only certified electrically isolated intrinsically safe equipment of ignition protection category EEx ia IIC may be connected. This requirement applies independent of the required Category and also if the device is not operated in the hazardous location.
