Predictive Maintenance Paper Machines Conveyors Often in paper and plastics manufacturing locations rolling element bearings are difficult to monitor because of their slow speeds The 1x running speed of the bearing may be lower in frequency than the low frequency range of a typical piezoelectric accelerometer For these applications IMI Sensors offers low frequency accelerometers In these models the discharge time constant has been extended thus allowing the sensor to monitor slower speeds down to 12 CPM 0 2 Hz These sensors are ideal for both permanent mount applications and route based applications They are all welded hermetic case isolated construction and built to survive harsh environments Accelerometers for Slow Speed Predictive Maintenance Slow speed applications such as slow moving roller element bearings in a paper mill produce lower vibration levels Consider increasing the sensor s sensitivity to 500 mV g thus increasing signal resolution in these applications Precision ICP Accelerometer Model 626B01 n Low noise floor n Low frequency response to 12 cpm 0 2 Hz n Full sweep calibration See page 90 for more information Low Frequency 500 mV g Accelerometers Precision ICP Accelerometer Model 625B01 n Side exit ring style n Low frequency response to 12 cpm 0 2 Hz n Ceramic sensing element See page 88 for more information IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx Low Cost Industrial ICP Accelerometer Model 601A02 n Low Noise See page 84 for more information Low Frequency Industrial ICP Accelerometer Model 625B02 n Full sweep calibration certificate provided See page 90 for more information Low Frequency Industrial ICP Accelerometer Model 626B02 n Full sweep calibration certificate provided See page 90 for more information 18 visit us online at www imi sensors com 1 716 684 0003
