The VeriFast™ LVDT system is designed to determine if a fastener or part is present and in the correct orientation during welding applications. Its high-resolution sensing capabilities, the speed of operation, low maintenance requirements and ease of integration into existing processes makes it the ideal solution for demanding nut and stud welding applications.
Why use a VeriFast LVDT?VeriFast LVDT technology has significant features and benefits, most of which are derived from its fundamental and physical principles of operation or from the materials and techniques used in its construction.
The LVDT system has an extremely high measurement resolution. When taking into consideration system signal noise, the practical resolution is 0.0009” (0.02 mm) which enables the system to effectively detect minute changes in process conditions.
Unaffected by foreign matter such as grease, oil, water and weld dust
The LVDT coil is contained inside CenterLine’s extended body ‘S’ series 2, 3 or 4 weld bodies.
Longer mechanical life
There is no contact between the LVDT’s core and coil structure, normally no parts can rub together or wear out.
Internal high-permeability magnetic shield minimizes the effects of external AC or DC fields. Both the case and core are made of corrosion resistant metals.
The VeriFast LVDT is engineered specifically for integration into CenterLine weld bodies.
Detection CapabilitiesThe VeriFast LVDT can be used to detect the following conditions:Weld pin extended position (system ready to load part and fastener)
- Weld proceed (presence and correct fastener or part orientation)
- Weld pin retracted
- Nut is upside down
- No fastener detected
- No part detected
