2.  What is Seismic Vibration?  How do you measure Seismic Vibration?  When do you measure Seismic Vibration?  Why do you need to measure Seismic Vibration?  Seismic Sensors  Seismic Transmitters  Seismic Switches  Seismic Vibration Monitoring

4.  Of, subject to, or caused by an earthquake or earth vibration  Earthshaking  lacking stability or fixity or firmness  of enormous proportions or having highly significant consequences  Basically nothing good

5.  In our field Seismic vibration has to do with the case vibration of a machine  Not the actual earth vibration

6.  Acceleration  Change of velocity over time  Units = g  Velocity  Distance travelled per unit time  mm/s or ips(inches per second)  Displacement  Change of position  um or mil

7.  Accelerometers  Ex: TM0782A  Velocity Sensors  Ex: TM0793V  Displacement Sensor  Ex: TM079VD

8.  Use for measure absolute vibration bearing at bearing point  Bearing or housing vibration

9.  To detect occurring or developing problems due to machinery imbalance, misalignment, looseness, rolling-element bearing failure, gear defects, etc

10.  Accelerometers  TM0782A  Accelerometer with Integral Cable TM0783A  Low Power TM0784A  Hi-Temp. TM0785A  Side-Exit TM0786A  Ultra-Hi Temp TM0787A

11.  Velocity Sensors  TM0793V  Side-Exit TM0796V  Explosion Proof TM016-793  Low Frequency Velocity/ Displacement TM079VD

12.  TR1101  Measures machinery case vibration  3-Wire Transmitter  4-20mA output in acceleration, velocity or displacement  TM016  2-Wire Looped Powered Transmitter  4-20mA output in acceleration or velocity

13.  PT580  Digital Vibration Switch  Acceleration and Velocity  4-20mA output  VS102  Electronic Vibration Switch  Velocity  4-20mA output  PT500  Mechanical Vibration Switch  Acceleration

14.  DTM 20  DM200  PT2060
