1 End Winding Remote unit PNR: Remote unit and 6 x One-Axis optical, MIC-Accelerometer Frequency response 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: 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 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: Hz Page 1 of 5

5 Scope of Delivery- Order No. Set: include the Remote unit and 6 x 1 axis Sensor include: 1 x End winding remote unit for 6x2 Acc optical Sensors 6 x Axis optical ACC Sensor length 10m BENEFITS 100% Fiber optic passive Solution 1 axis 2 or 3 axis with same design, and nearly same dimension of the sensor and feed through Higher resolution and lower noise then all other products on the market less sensitivity to cable vibration in the generator highest accuracy Multi channel feed through possible one hole instead of multiple holes Fiber go also from feed through to Remote unit so no RF interferences from generator to the monitoring computer Multi fiber extension cable from feed through provides neat solution The Sensor can be Field calibrated after installment to exact 100mV/g with the Test Point. with the test point possibility, enables calibration as DC and AC are correlated. Dual and 3 axis sensor with very low cross sensitivity so accurately measuring vibration at one point of measurement. exreme low weight, only max. 20g Page 5 of 5
