Product description:

  • EnDaL vi sound is a versatile modifiable data logger for demanding transport monitoring and safe machine handling.
  • Highly sensitive shock sensors immediately trigger acoustic warnings when the set limit values are exceeded.
  • Certain movement sequences can be quickly corrected by the staff and objects can be protected against improper handling.
  • EnDaL vi sound also measures temperature and air humidity.
  • Depending on the needs of the user, additional sensors for air pressure as well as up to 4 digital signals can be connected.
  • All measured values are stored in the data logger independent of the battery status and can be analysed after transfer to a PC.
  • Extensive accessories as well as userfriendly configuration and parametrisation enable EnDaL vi sound to provide a wide range of options for recording measurement data.
  • The measuring system is also available in a clean room design.
  • This is particularly well suited e.g. for transport monitoring of optics systems or lithography systems for semiconductor and microsystem technology, but also for transporting valuable art objects or other
    highly sensitive goods.
  • The convenient ENCUR software for programming and data analysis is included in the delivery.
