The Data Logger LB 5340 is a universal data acquisition system, which could be used for a variety of measuring applications in all scopes of radiation protection measurement techniques.

    The 19“-rack design enables the usage in a desktop housing or as a rack mounting device. Both versions are characterized by a compact and visually attractive designed metal enclosure, and equipped with a coloured touch-screen. For service purposes a mouse or keyboard can be connected.

Due to the modular design the LB 5340 can be equipped, according to the application required, with different detectors, sensors and peripherals by means of modules – max. 6. The selectable modules are:

  • ABPD-board for pseudo-coincidence
  • Detector DAQ-board
  • Universal IO- board
  • 8-fold current-output-board
  • Relay- board with 5 double pole relays or external 8-fold relay card
  • Power supply for detectors (4 x Tuchel-connectors)

The LB 5340 is equipped with well-engineered software, which makes various system configurations easy and straight forward.

The configuration of the virtual channels are individually programmable for each channel via provided software assistants.

There are various service functions for the performance of periodical tests: Background measure­ment, calculation of calibration factors, plateau measure­ment and calculation of pseudo-coincidence factors.

The measured values and graphics are shown by means of different depictions in pre-defined screen pages.

Remote access and configuration import & export is supported via USB and Ethernet ports and LB 5340 remote configuration utility software.
