S7TW Loop Powered LVDT Amplifier |
|
The RDP Electronics S7TW 2 wire 4-20mA LVDT signal conditioning amplifier is specifically designed for use with LVDT and inductive transducers.
The tough aluminium case encloses a fully adjustable and configurable LVDT signal conditioning amplifier which can be matched with a displacement transducer to give 4-20mA loop powered interface.
The high level of environmental protection allows the LVDT signal conditioning amplifier to be situated close to the transducer, even if the transducer is located on a dirty or wet machine. Cables are securely fastened using screw terminal blocks and seal through compression glands.
The S7TW amplifier is compatible with all RDP Electronics LVDT however, the following need to have a free modification called TM202.
