1 ccelerometer Catalogue EEx Types: 4391E, 574, 5874, 8326 Non EEx Types: 4391, 8315, 8324, 8325, 8327, 8331, 8332 Brüel & Kjær Vibro has more than 5 years experience in the design, manufacture and application of high quality vibration monitoring instrumentation and sensors. We recognise that reliable vibration based condition monitoring is directly dependent on the quality of the front-end transducer used and that correct sensor selection is the critical first step in the design of any vibration monitoring system. ccelerometers are widely accepted as the most practical, robust and reliable method of measuring machine vibrations. From a technical point of view, their wide frequency response of up to several khz provides earlier indication of rolling-element bearing faults, gear mesh problems and the like, than can be detected by low frequency transducers. From a practical standpoint, accelerometers are easy to install because no gap setting or Selection Guide EEx applications calibration is required, and their rugged industrial design ensures that they provide years of uninterrupted accurate vibration monitoring. dditionally, the integrity of the machine or bearing housing is not compromised because they are directly mounted on the machine housing. Brüel & Kjær Vibro is a pioneer in the development of accelerometers. Our founders developed one of the world's first accelerometers during the early 194's. Since then we have continuously been developing our product range which now includes accelerometers that can be used in explosive environments and in applications with extreme temperatures or high radiation. Our patented CCLD (an industrial standard for accelerometers with built-in amplifier) shear type accelerometer, for example, was developed when results from the field pplication Type 13 C 26 C 48 C Certified to Non EEx applications pplication Type 13 C 18/26 C 48 C showed that compression accelerometers were unsuitable for monitoring in environments with strong magnetic fields, such as those found on generators. The most cost effective accelerometer design is the constant current, or CCLD type. These accelerometers are suitable for most standard industrial applications, however their internal electronics prevent them from being used at temperatures exceeding 13 C. For high temperature applications a charge type accelerometer with an external pre-amplifier is necessary. These accelerometers do not have any built-in electronics and can withstand harsh environments of extreme temperatures and/or high radiation. In general the charge type accelerometers withstand temperatures between 26 C and 48 C.

2 EEx pplications Charge type accelerometers Type 4391E Because of its low weight and small dimensions, Type 4391E is well suited for off-line monitoring or for use in permanent vibration monitoring installations where the space for installation is limited. The base is isolated to prevent ground loops. The accelerometer is of a "shear" construction to significantly reduce transient temperature and base strain outputs, while maintaining a high resonance when mounted and a high operating temperature. Type 4391E can be used for permanent monitoring installations and offline measurements. The accelerometer can be used in a zone environment. Type 574 This is designed for permanent vibration monitoring installations in a wide variety of applications. It is intended as a general purpose monitoring transducer and it can even be used in areas rated potentially explosive (zone ). Type 574 is well suited for use with permanently installed machine condition monitoring systems. This accelerometer is developed to meet the requirements of permanent vibration monitoring installations in a potentially explosive atmosphere. The accelerometer utilises a "shear" construction that significantly reduces transient temperature and base strain outputs while maintaining a high resonance when mounted. Type 5874 The Type 5874 Charge ccelerometer is designed especially for monitoring the vibration of a wide variety of plant machinery in harsh environments within potentially explosive atmospheres. It was originally designed for monitoring gas turbine applications that require long mean time between failures, but it is equally well suited for industrial machine installations. The Type 5874 has a 3 meter long, integrated hard-line cable with an intrinsically safe barrier at the end of the hard-line. lower temperature soft-line cable can be attached to the socket of the barrier. The accelerometer itself is TEX certified. Both the accelerometer and the barrier can be used in a zone 1 environment. The accelerometer utilises a compression element to provide excellent temperature stability and a wide operational bandwidth. Type 5874 with 3 meters hard-line cable CCLD type accelerometer Type 8326 This is an industrial accelerometer especially designed for vibration measurements in the rugged environments of plant machinery. The accelerometer is the EEx version of Type Type 8326 offers a very wide dynamic range and a low noise floor. The cable configuration provides excellent resistance to electromagnetic noise pick-up. The accelerometer incorporates a hybrid circuit with a pre-amplifier. Signal ground is isolated from the mounting surface and outer case, to prevent ground loops. The accelerometer is intended for permanent monitoring installations and off-line measurements, and for use in a zone environment. This accelerometer utilises a "shear" construction to significantly reduce transient temperature and base strain outputs, while maintaining a high resonance when mounted and a high operating temperature.

The base is isolated to prevent ground loops. The accelerometer is of a "shear" construction that significantly reduces transient temperature and base strain outputs while maintaining a high resonance when mounted and a high operating temperature. This is designed for permanent vibration monitoring installations in a wide variety of applications. It is intended as a general-purpose monitoring transducer and it can even be used in areas where there is radiation. The accelerometer utilises a "shear" construction that significantly reduces transient temperature and base strain outputs, while maintaining a high resonance when mounted and a high operating temperature. Type 8315 is well suited for use with permanently installed machine condition monitoring systems. Type 8324 is especially well suited for use in nuclear power plants and in areas with high temperatures. The accelerometer utilises a compression type element to provide excellent temperature stability and a wide operational bandwidth. Type 8324 is well suited for use with permanently installed machine condition monitoring systems. Type 8324 Type 4391 Type 8315 with integrated cable CCLD type accelerometers Type 8325 and 8327 Type 8331 and 8332 Type 8325 and 8327 offer a very wide dynamic range and a low noise floor, and the cable configuration provides excellent resistance to electromagnetic noise pick-up. The accelerometers incorporate hybrid circuits with a pre-amplifier. Type 8327 is intended for use where the signals contain components that could overload the It utilises an active 2-pole low pass filter for resonance suppression. Signal ground is isolated from the mounting surface and outer case to prevent ground loops. Type 8325 and 8327 have top-connectors. These accelerometers utilise a "shear" construction that significantly reduces transient temperature and base strain outputs, while maintaining a high resonance when mounted and a high operating temperature. Type 8325/8327 with integrated cable Type 8331 and 8332 have the same features and characteristics as the 8325 and 8327, except they are fitted with side cable connectors and center bolt mounting allowing easy dismounting with cable attached. Type 8331/8332 3

4 Common Features The accelerometers are well suited for use with permanently installed machine condition monitoring systems. Unified sensitivity is used, which means the accelerometer can be interchanged without affecting the sensitivity since all are pre-adjusted during manufacturing within a few percentages of their nominal sensitivity. Proper selection of high-quality signal cables (double-shielded, twisted pairs) greatly reduces noise pick-up caused by electromagnetic interference from, for example, arc welding or radio transmitters. Furthermore, problems with ground loops are effectively eliminated.
