Page 8: Precautions
Check all equipment packaging for transporation damage. Report any damage to the transporter and to Kistler. The equipment should be used only under the specified ope- rating conditions and must be protected against excessive dust and mechanical stress (shock, vibration, etc.). -
Page 9: Product Types
Important information With normal coaxial connections, as used with most piezoelectric sensors, the shield utilizes a signal return lead with connections over long distances. Therefore, different ground potentials can produce equalizing currents in the cable shield. In this case, it may be necessary to forgo grounding at both ends to prevent ground loops. - Page 10 Non-hazardous and hybrid/mixed area AE system Type 8152Cxxx0001/2 ATEX AE-sensor with polyurethane cable Type 8152Cxxxxxx1/2 ATEX AE-sensor with steel braid conduit Type 5125C2 and Type 5125C3 non-hazardous AE-coupler Fig. 1: Type 8852A...

Page 13: Ae-Piezotron Sensor Type 5125C
Product description The Type 8152C AE sensor is available in either a non- hazardous sensor type for completely non-hazardous installations (designated by the “N” in the system numbering) or a ATEX/CSA sensor type for hybrid/mixed installations (designated by a “H” or “M” in the system numbering). “H”... - Page 14 Non-hazardous and hybrid/mixed area AE system Next, the coupler applies high-pass and low-pass filtering in order to remove that frequency content which is of no interest and measures the RMS level of the resultant signal. Finally, the RMS level is converted to a representative DC level. The coupler outputs available to the user system are the DC representation of RMS level, a 4-20 mA representation of RMS level, an adjustable switch closure of the RMS level...

Page 15: Wideband Zener Barrier Type 5252A1
Product description 3.5 Wideband zener barrier Type 5252A1 The Type 5252A1 wideband zener barrier is made to operate with a cut-off frequency of >6 MHz. The wide bandwidth allows for the barrier to be used with the Type 8152C AE- sensor, which has usable frequencies up to 900 kHz. -
Page 16: Hazardous And Non-Hazardous Area Installation
ATEX/CSA and a barrier must be used to couple the sensor to the coupler. Refer to Fig. 6 for details. Kistler Type 5252A1 is recommended to ensure full usage of the real-time AE output of 900 kHz. - Page 17 Hazardous and non-hazardous area installation Only ATEX sensors Type 8152C... with serial number SN 4944583 and higher are compatible with the Type 5252A1 wideband zener barrier. Fig. 7: Type 8852AxxxxxxH2 system configuration. Type 8152C sensor lies into zone 2 hazard area. Type 5125C non-hazardous coupler lies in the safe area.

Page 21: Connection Of The Ae Sensor To The Ae-Piezotron Coupler
Mounting, installation & operation 5.2.2 Connection of the AE sensor to the AE-Piezotron coupler In order to guarantee a higher level of interference immunity, the AE sensor is connected via a triaxial cable. In a comple- tely non-hazardous system, the connection is made via the 2-pole terminal J4 inside the instrument (see Fig. -

Page 26: Cable Length Recommendation For Raw Ae Output
Non-hazardous and hybrid/mixed area AE system A fine jeweler’s screwdriver may be used to make this adjust- ment. Care must be taken to avoid excessive force on the adjustment screw, which may damage the pot or the PC board. The raw AE-out is filtered through a bandpass filter and is provided for monitoring on a data acquisition system, oscil- loscope, digital multimeter or spectrum analyzer. -
Page 27: Application Example
Calibration & maintenance 6. Application example The AE-sensor is particularly suitable for measuring acoustic emissions above 50 kHz in the surface of machine struc- tures. These sound emissions (AE) occur, for example, during plastic deformation of materials, crack formation and propagation, fracture or friction. -
Page 28: Calibration & Maintenance
Non-hazardous and hybrid/mixed area AE system 7. Calibration & maintenance 7.1 General The AE system cannot be repaired in the field. The sensor and the coupler must be returned to the factory for service or re-calibration. 7.2 Care & cleaning In general, dust or foreign material should be cleaned from the enclosure using a soft brush or a clean, dry dust cloth. -
