The Data Logger LB 9000 with its PC software is a universal data acquisition system for a variety of detector systems in radiation protection. All kinds of different probes, sensors and peripheral devices can be connected.

The Data Logger has a modular structure so that it can be set up and retrofitted depending on the application. Intelligent modules are used to which the detectorsa and sensors are connected:

  • ABPD-board for pseudo-coincidence measurement
  • Detector DAQ-board
  • Universal IO-board
  • 8-fold current-output-board
  • Relay-board with 8- or 16-fold relay card with double changers
  • Detector Power Supply module (4 Tuchel-connectors)

If necessary the modules can be used in a multiple way. Up to 10 slots are available so that you can configure a large-scale system with up to 50 virtual measuring channels combined with 20 analog outputs and 70 digital outputs.

The system can be upgraded to max. 15 boards by using an additional rack.

The Data Logger features the latest state of art technology and a technically mature software system that can be configured by the user. It takes over the complete control of all modules, calculation and integral calculation and the graphical presentation on the screen.

All measured values, different integral values and exceeding or not reaching limit values can be monitored and output depending on the user´s requirements.

The software has a very userfriendly graphical interface. There are various service functions for periodical testing: Background measurement, determination of calibration factors, plateau measurement and determination of pseudo-coincidence factors.
