1 Electronics & Software Piezotron Coupler Type 55C... Acoustic Emission Coupler for Safe or Hazardous Locations ATEX/IEC/Ex and CSA The AE-Piezotron Coupler processes the high frequency output signals from Type 85C... Kistler Piezotron acoustic emission sensors. Type 55C0xxx is designed for use in industrial hazardous locations, ATEX/IEC/Ex and CSA. Gain and integration time constant of the built-in MS converter can be configurable upon order. Types 55C0 and 55C are designed for standard industrial applications. Gain, filters, and integration time constant of the built-in MS converter are designed as configurable parameters. This allows for the best possible adaptation to the particular monitoring function.

SENSO TEMINATION 0 SHOWN Description The AE-Piezotron Coupler, with built-in MS converter and alarm switch, has been specially designed for the processing of high frequency sound emission signals from Kistler AE-Piezotron sensors. In the case of standard Type 55C0 or 55C, the unit is delivered with a gain set to x0, while the gain can be set with a jumper to x or x00 by the user depending on the signal amplitude. In the case of the IS/ATEX version, this must be configured upon order and cannot be changed later on. The amplifier has two series connected second order filters defaulted with a 50 khz highpass filter and a MHz low-pass filter. In the case of standard version Type 55C0 or C, the low-pass and high-pass filters can be modified by plugging in alternate filters. The integration time constant of the MS converter can be freely selected by the user and a default value of. ms is delivered. In the case of the ATEX/IS version, the MS time constant must be configured upon order and cannot be modified by the user. 86 [3.38] 45 [.77] 44 [5.67] [0.47] [0.83] Type 85C... SENSO TEMINATION 0 SHOWN Outline drawing for Types 55C... (units in mm [in]) 38 [.50] 45 [.77] 9 [.4] #6 3 GOUND STUD The alarm switch is set with a potentiometer. The switching threshold set point can be monitored by monitoring the resistance at the 'Alarm Switch' output with a DMM. The output of the alarm switch is electrically isolated by an optocoupler. On a standard Type 55C0 or 55C, three analog output signals (Filtered aw AE Out [0±5 Vpeak], MS Out [ V or ma Out]), as well as a digital output signal (alarm switch), are available at the connectors. On an IS/ATEX version, only MS, ma and alarm switch outputs are offered. Page /

2 Application The AE-Piezotron Coupler Types 55C..., in conjunction with the Kistler Piezotron acoustic emission sensor Type 85C..., are well-suited for the monitoring of machines and tools in industrial production or leakage monitoring in petrochemical industries and/or hazardous locations, IEC/Ex and CSA). For more details on various possible configurations and suitable type numbers, please refer to page or Type 85C sensor and Wide Band Zener Barrier Type 55A datasheets. Connection The AE-Piezotron sensor is connected directly to the terminals inside the AE-Piezotron coupler in accordance with the wiring diagram on the underside of the cover. The coupler can be supplied to be compatible with cable gland or conduit adaptor sensor connection to provide a leak-tight connection. Additional wiring instructions are detailed in page 3 below when an IEC/Ex and CSA Zener Barrier are in use. Page /
