THE VIBRATION MONITORING SPECIALISTS PRODUCT INFORMATION The transducer series CHB 1102/1115/1117/1128 is an external single direction low frequency accelerometer intended for the use with PCH 1026 wind turbine and structual vibration monitor. The external single direction accelerometer is used for advanced nacelle monitoring with distributed pick -up points. A separate cable with integrated D-Sub and M12 connector makes installation and connection to the vibration monitor very easy. Uses The CHB 1100-series is used together with the PCH 1026 wind turbine and structural vibration monitor for advanced nacelle monitoring. Examples are monitoring of low frequency torsional vibrations between the gear box output and the generator. Furthermore, the CHB accelerometer is suitable for basic gear mesh monitoring of the gear box up to 1000 Hz. Self-Test The monitor will issue a System-Error on Self-Test fail or if an accelerometer is disconnected. The accelerometer must be assigned in the PCH 1026 vibration monitor setup for this function. Easy installation The CHB accelerometer has a build in memory chip, where factory information is stored: serial number, type number, sensitivity and self test parameters. When the accelerometer is connected, the monitor will read the information from the memory chip and automatically adapt to the specific transducer settings. This means the accelerometers can be interchanged freely without having to change parameters manually. Every 30 seconds the monitor reads the chip in order to verify that the accelerometer is still connected and indentified. After power-on the monitor will settle for 20 seconds. The settling time after disconnecting/connecting a CHB accelerometer is 3 sec. During settling the PCH 1026 will perform a Self-Test of both internal and external accelerometers.
