End Winding Remote unit PNR: 9600.30.180 Remote unit and 6 x One-Axis optical, MIC-Accelerometer Frequency response 1 1000 Hz Easy installation on the end-winding High voltage electrical insulation between sensor and instrumentation Frequency bandwidth 1 khz Optical transmission up to 200m Complete EMI/RFI immunity Plug-and-play system MTBF > 100'000 hours Test point calibration possibility PNR: 9600.30.101 include 6 x 1 acc Sensor DESCRIPTION The MICRONOR one-axis optical accelerometer is suitable for remote monitoring of end-windig vibration in one orthogonal direction. The sensor is completely passive which makes it ideal for areas where piezoelectric and piezoresistive accelerometers are not useable. Thes sensorsystem is 100% passive, including the optional fiber feedthrough and the connection to the electronic. The optical transmission can be up to 200m. This one-axis optical accelerometer system is use in applications such as extremely high voltages, severe electromagnetic and highly explosive gas atmospheres. The optical design ensures an excellent electrical insulation between the sensor head and the instrumentation, The sensorbody is made of noryl PPO with no metallic elements. The optical fiber is embedded and protected by integral cable. The MICRONOR MR388 End Winding Sensorsystem Part. Nr. 9600.30.180 convert vibration of one axis into single ended electrical signals. This system intend to measure vibrtaion of power generator end winding. The frequency response range: 1-1000Hz Page 1 of 5
