Temperature limits 2.1 OPTIFLUX 4300 • In general the OPTIFLUX 4000-EEx flow sensors are suitable for an ambient temperature range of -40°C … +60°C. The temperature range is often limited further by the liner type used (refer to Quick Start). • The minimum process temperature is -40°C. • The maximum process temperature Tp is dependent on the required temperature class T6/T5..T3, the

Supplementary Instructions for ATEX applications

1.1 Scope of the document

These instructions are applicable only to the explosion-protection version of the TDR level transmitter. For all other data, use the Quick Start and other chapters of the Handbook. If you do not have these documents, please contact the nearest office or download them from the manufacturer’s internet site.

INFORMATION!

The information in this chapter only contains the data applicable to explosion protection. The technical data for the non-Ex version in the Handbook shall be valid in its current version, provided that it is not rendered invalid or replaced by this chapter.

WARNING!

Installation, commissioning and maintenance may only be carried out by «Personnel trained in explosion protection».

1.2 Device description

This device is a 2-wire level transmitter that uses TDR (Time Domain Reflectometry) / Guided Radar technology. It measures the level, distance, volume and mass of liquids, liquid gases, pastes, powders, slurries and granular products. It is also suitable for the continuous and simultaneous measurement of level and interface of 2 liquids. Measurements are displayed via a DTM (device type manager) for remote communication or an optional integrated display screen with wizard-driven setup and online help functions.

The level transmitter is approved for use in potentially explosive atmospheres when equipped with the appropriate options.

Ex ia-approved devices can also be equipped with an external sensor to measure process temperature, pressure, etc.

1.3 Standards and approvals

DANGER!

In compliance with European Directive 94/9/EC (ATEX 100a), the ATEX version of the device described in these Supplementary Instructions conforms to European Standards EN 60079- 0:2006, EN 60079-1:2007, EN 60079-11:2007, EN 60079-15:2005, EN 60079-26:2007, EN 61241- 0:2006, EN 61241-1:2004 and EN 61241-11:2006. The Ex ia and Ex d [ia] versions are certified for use in hazardous areas by the KEMA Quality B.V. under KEMA 04ATEX1219 X.

WARNING!

Carefully read the ATEX approval certificate. Obey the boundary conditions.

2.1 Precautions

2.1.1 General notes

WARNING!

When you install the device, obey the conditions in the EC-Type Examination certificate. These conditions include:

•The special conditions for safe use.

•The Essential Health and Safety Requirements.

DANGER!

This installation must agree with EN 60079-14: Electrical installations in hazardous areas.

2.1.2 Electrostatic discharge

DANGER!

Risk of electrostatic discharge from the blue plastic sun cover, the conduit of the remote housing option and the optional plastic protective sheath for the single rod probe. Make sure that all personnel and equipment are correctly grounded.

Figure 2-1: ESD warning sticker (below the device nameplate)

1Text: Plastic Parts

2Text: Warning! Potential electrostatic hazard — see instructions

Take the necessary antistatic precautions if you:

•handle,

•install or

•use

the device in potentially explosive atmospheres. Do not install in a location (near to ventilation systems, for example) where the electrostatic charge can increase.

WARNING!

FEP-coated single cable probes are for Gas group IIB only.

2.1.3 Special conditions

WARNING!

Aluminium housing: Possible source of ignition in a potentially explosive atmosphere. The housing is made of either aluminium alloy or stainless steel. If the device has an aluminium alloy housing, make sure that iron/steel objects do not hit or rub against the device.

2.2 Operating conditions

The allowable ambient temperature and corresponding flange temperature range for the device depends on the ATEX equipment category and temperature classes marked on the nameplate.
