Upgrade Light Tester Package (ULTP)

upgrades the reynolds rt6 / rt5™ light tester
Label Verifier Unit

Over 90% of RT5 & RT6* users across Europe and the United States have benefited from ULTP

This high performance tester upgrade kit is designed to be installed on a Reynolds RT5 / RT6™ light tester. At the heart of the RT5 or RT6 light tester is the light detector head. The standard analog photomultiplier system will degrade over time, requiring either constant adjustment or regular replacement. Sencon can replace this unit with a solid state electronics pack which, together with a simplified lighting system.

  • benefits
  • Improved reliability and stability
  • No degradation of sensitivity over time
  • Reduced spoilage
  • Increased speed capability
  • Reduced maintenance & running costs
  • Long life expectancy

Two upgrade paths are available

Standard upgrade ULTP

The standard upgrade package uses six commercially available long life automotive headlamps and a quartz-halogen lamp. Lamp replacement and cleaning of the detector lens are the only scheduled maintenance tasks.

Standard ULTP

  • Improved machine information
  • Fault diagnostic facilities
  • Easy set-up and operation
  • Simpler solid state electronic detector system
  • Totally replaces old photo multiplier system



As the ULTP light detector does not become less sensitive over time, adjusting the system sensitivity is not necessary. Typically, machine adjustments are only made during installation. This is in sharp contrast to standard electronics which must be adjusted at least once per shift.



LED Upgrade ULTP

The more advanced LED Upgrade Package offers further performance enhancements by installing a solid state LED lighting array which is even better matched to the sensitivity of the detectors. In addition, the detector head and the processor have been redesigned to operate at higher speed.

LED upgrade

  • Improved sensitivity of the system
  • Reduced maintenance frequency
  • Further minimizes downtime
  • Increased throughput
  • Improved resolution of the blow-off control
  • Removal of the in-feed lamp

    A range of options is available for the LED upgrade, depending on the system already installed. Contact Sencon for details.


"Flash Control" for improved system efficiency - The faster on-off switching possible with LEDs has enabled the inclusion of a proprietary "Flash Control" function that switches off the LEDs if the detectors are flooded with too much light due to a damaged can or an empty pocket. This prevents the detectors from being blinded, eliminating the need for recovery time before inspecting the next can.
