LVDT gauging sensors are equipped with a plunger and fitted with a return spring. The measuring probe can be interchanged with commercially available measurement probes. Measurement probes are primarily used for the measurement and inspection of work-piece geometries (length, width, diameter, thickness, depth, height, etc.).

Application

Application

 N/A Gauges from Micro-Epsilon have many possible fields of application. Due to different measuring ranges and configuration settings, the gauges are suitable for numerous measurement and inspection tasks. Combined with multi-channel controllers, the DTA gauges are often used for dimensional measurement and inspection tasks, e.g., in automated quality control, R&D and production monitoring.

Additional Information

N/A LVDT gauge sensors DTA-xG8 are primarily used for the measurement and inspection of workpiece geometry (e.g. length, width, diameter, thickness, depth, height). Therefore, different measuring ranges from ±1 mm to ±10 mm are available. The gauges are particularly suitable for applications involving a large number of pieces.

These gauges have an axial cable outlet and are equipped with either a plain bearingguided plunger and a return spring, or with a pneumatic push rod. Depending on the measuring object, different probe tips are available. DTA gauges can be operated with every MSC controller. Depending on this controller, single-/dual-/multi-channel measurements are possible. In addition to the well-established analog output, modern fieldbuses are available for integration purposes.
