ATEX ManualFor the intrinsically safe charge amplifier type 2667 - all variants
Content:
Product data sheet
Mounting details with typical loop (*)Declaration of Conformity
ATEX certificate
Notice to request the ATEX manual in other EU languages
(*) for installation with devices from other manufacturers than Brel & Kjr Vibro, please read the
appropriate manuals or contact the manufacturer of your device for installation instructions.
Customer responsibility
The customer is solely responsible for the correct layout of the electric system with regard to theapplicable explosion protection regulations as well as for the correct operation of the product. Theexplosion protection- and safety regulations have to be observed and if necessary verified by anexpert.
In case the system is installed by a sub-contractor on behalf of the customer, the product must not beput into operation until the sub-contractor has proven that the system has been installed correctly andconforms to the valid regulations by means of an installation certificate.
The customer also has to notify the notified body about the installation and operation of explosion-protected systems as well as of any substantial changes or maintenance work done to the installation.

Charge Amplifier type 2667 data sheet
1. Application
Charge Amplifier: Certified Intrinsically Safe to foruse in hazardous areas.
II 3GEx ic IIC T6
2. UsageType 2667 is intended for connection to charge type accelerometers in areaswith potential risk of explosions, when monitoring plant machinery in harshenvironments, for industrial machine installations and for gas turbineapplications requiring long mean time between failures.
The type 2667 has a differential input which improves the signal/noise ratioin strong electromagnetic fields when used together with balancedaccelerometers, such as B&K Vibro Type 5704.
To protect the Type 2667 from harsh environmental conditions, such ashumidity and vibration, it should be mounted in a junction box in conformitywith IP 65, as available from Brel & Kjr Vibro.
Type 2667 is available in a number of versions when other amplificationfactors or filtering ranges are required.

Electrical layout
EMC
EN61326-1:2006To avoid possible negative influences caused by a surge impulse (accordingto EN61000-4-5), cable EL3006 or AC-900 between 2667 and barrier mustbe used.
Note:All values are typical at 250C (77
0F), unless measurement
uncertainty is specified. All uncertainty values are specified at 2
(i.e.expanded uncertainty using a coverage factor of 2).

4. Special conditions for safe use The terminals 1-6 of the apparatus shall be connected to certified
barriers or isolators located in the non hazardous area.
It is recommended that the Charge Amplifier is mounted in accordancewith the Principle Diagram for Intrinsic Safe Monitoring System, Brel &
Kjr drawing no. EW2013 dated 1998-05-26, or Brel & Kjr drawingno. EW2753 rev. B dated 05.05.2008.
The Charge Amplifier shall be mounted in a junction box connected toprotective earth.
