Benefits

What can upgrading do for you?

  • VSV is present to enhance efficiency over a wide range of air speeds. 
  • Proper monitoring of VSV position with LVDT allows the VSV to function more efficiently. 
  • LVDT position allows remote monitoring and accurate position of VSV to be known at all times. 
  • LVDT signal can be used for data or alarm processing.

How we get you there

  • The VSV is part of the high-pressure compressor (HPC) assembly and thus difficult to access. 
  • A LVDT system can be installed allowing remote monitoring of VSV positions. 
  • The LVDT will be mounted on the compressor front frame (CFF) at approximately the 9 o’clock position. 
  • LVDT is mechanically connected to the VSV union ring by a pin and a clevis arrangement. 
  • Union ring movement will send a signal back to the operator through the LVDT. 

Installation will include: 

  • LVDT transducer and hardware 
  • Remote signal conditioner and hardware 
  • Cable between signal conditioner and LVDT
