Displacement measurement sensors
OD Precision

Measuring each dimension with high precision

Your Benefits

  • Non-contact measurement improves quality inspection during production
  • Surface-independent measurement algorithms ensure minimum machine downtime, regardless of surface gloss or color
  • Reduced processing times as a result of the high measuring frequency of up to 10 kHz
  • Simple, cost-effective solution for challenging measuring tasks due to a variety of sensor models
  • Optional stand-alone operation via RS-422 means the OD Precision offers maximum performance at lower investment costs
  • High visibility LC display enables simple, cost-effective setup
  • Many interfaces for simple integration into an existing production environment


Measuring each dimension with high precision

The OD Precision is a high accuracy, optical measuring system for measuring difficult object surfaces. In addition to glossy and dark black surfaces, it can also measure transparent and semi-transparent materials. The OD Precision is the only displacement measurement sensor that can connect three sensors to one controller, which reduces the amount of hardware required and makes it easier to measure the x-, y- and z-axes., e.g. for measuring the evenness of surfaces. In order to reduce investment costs, the sensor can also be operated via RS-422, thus eliminating the need for a controller unit.
