PBI-Dansensor analyzer for continuous monitoring of headspace oxygen gas + carbon dioxide gas online and in real time. Designed for flow wrapping and bagging packaging machines.Principal use for M.A.P food package. Comprises of inline oxygen gas analysis (carbon dioxide detector optional ), PFC - proportional flow control and periodic flush back purges to prevent gas lines from blocking.

PLEASE NOTE:
In April 2012 PBI-Dansensor will discontinue the MAP Check Combi II – PFC.
The MAP Check Combi II – PFC will however continue to be supported, until at least 2017 as per PBI-Dansensor’s current company policy (November 2011)

The MAP Check Combi II – PFC is being superseded by the MAP Check 3 – released November 2011.

MAP Check Combi secures the quality in Modified Atmosphere Packaging through on-line measuring and recording of the gas content in the package before sealing. Alarms are activated if the gas concentrations exceed the user specified levels. The analyser is specifically designed for both vertical and horizontal flow packaging machines.

MAP Check Combi is available in the following versions:

• MAP Check Combi – with spot-test function
• MAP Check Combi II – without spot-test function
• MAP Check Combi II – with automated flow control and without spot test
• The MAP Check Combi series is available with oxygen (O₂) sensor or a version measuring oxygen/carbon dioxide (O₂/ CO₂) combined.

Features

• Built-in sample pump
• MCC is delivered with stainless steel cabinet and
• MCC II is delivered with anodized aluminium cabinet
• Designed for both vertical and horizontal flow packaging machines (flow wrappers)
• MAP Check Combi II, PFC, only:
  • Integrated flow controller for controlling and saving gas
  • Flow control range from 0-800 litres/min
  • Flush back system for cleaning out impurities in the measuring system
  • Fast ROI due to gas savings

Packaging machine interface

The gas concentration alarms, system alarms etc. can be communicated to the packaging machines via relay output and RS 232. On certain machines it is possible to interface the program selection function via RS 232 which means that the packaging machine automatically executes the right program selection in the MAP Check Combi. The start-stop function of the entire system can be executed by the packaging machine.

Product program set-up
The gas content alarms for the on-line analyser are defined in product set-up programs (99 programs in total) which can be assigned a name/number to facilitate identification. One touch and the MAP Check Combi sets itself up to a particular product program.

On-line gas analysis – improved Q.A.
MAP Check Combi offers complete traceability. The measuring data, including any possible alarms during packaging and spot tests, is logged in the memory. Further ­more measuring data can be printed out on an external printer (optional) or transferred to an external computer, e.g. the computer controlling the packaging machines.

Principle of operation
MAP Check Combi is based on state-of-the-art technology which offers unprecedented advantages both in terms of the sensors and the electronics. A large touch screen based user interface allows for an extremely user-friendly programming of the analyser. Gas alarms (four for both O2 and CO2), which are easy to set up, communicate with the packaging machine. The alarms will be activated if the gas content does not follow the specifications. Self-diagnostics with alarm functions is monitoring the functional parameters of the analyser and a spot test can be performed with the random testing device.

The specifications concerning the gas composition in the package – min./max. O2 and CO2 – are set up in programs to which a name or a number can be assigned for easy identification. As already mentioned 99 set-up programs are available. A new program is selected by a touch on the screen and the analyser will automatically set up as programmed by the user. The program selection procedure can also be interfaced with the machine. When a program is selected on the machine it will automatically select the right program on the analyser, thus avoiding user-dependent faults.

MAP Check Combi & MAP Check Combi II are tested to be in compliance with EU regulation 1934/2004 on materials and articles intended to come into contact with food.
