Deskripsi
Linear Differential Transformer (LVDT)
Brand : Jiangyin No.3 Electronic Factory
QBJ series stroke sensor
System Overview:
The TD-1 hydraulic motor stroke sensor uses a medium-frequency displacement sensor as its primary element and is used to measure the stroke displacement of steam turbine hydraulic motors. It can be installed in any position, but must be at least the height of the mounting bracket away from magnetic conductors or metal objects. The sensor housing must be kept away from magnetic fields and high-current conductors.
Breakdown of Parts :
• Primary Coil: Center-wound coil energized by AC signal
• Secondary Coils: Two coils wound symmetrically on either side of the primary
• Core: Magnetically permeable rod that moves axially
• Housing: Cylindrical stainless steel enclosure
• Connector: 3-wire output configuration
• Mounting Flange: For fixed installation
• Cable Lead: Shielded cable for signal transmission
