Gamma 101P - Fill Level Inspection Monitor

PECO's versatile and time proven Gamma 101 inspection system delivers unsurpassed accuracy in fill level or contents inspection for a wide variety of applications.

Versatile Applications
The Gamma 101’s versatility is enhanced by flexible inspection windows that guarantee accuracy in a variety of applications from monitoring precise fill levels to bar length grading. The Gamma 101’s inspection window is adjustable up to twenty inches allowing it to easily accommodate larger containers or packages. Each container or package is inspected once. For a wide variety of multiple row or case inspection applications refer to PECO's Case Inspector brochure or data sheet.

Typical Applications

Identification of underfilled cans (“floaters”) prior to entering the cooler or warmer

Identification of overfilled cans (for minimum head space) prior to entering the cooker

Identification of gross underfills to monitor the filler

Identification of fine underfills to meet regulatory requirements

Solid contents verification for multiple fill products

Simultaneous high and low fill inspection

1. Underfill and Overfill Selection
Underfill or overfill can be monitored individually or simultaneously. The display will show the condition selected (for example, UNDERFILL ON).

2. Inspection Totals
Counting continuously, the Gamma 101P updates the display every second. The GOOD COUNT is the count of all containers that fell within acceptable inspection parameters. The BAD COUNT is the sum of all that did not, including; underfills, overfills and any optional inspection defect counts. The TOTAL COUNT is the sum of GOOD and BAD COUNTS.

3. Data Entry
The ENTER, CLEAR and numeric keys provide for entry to the system of all inspection parameters. When the Data is complete (as shown on the display) and the ENTER key is depressed, the system is activated. The CLEAR key allows the user to delete errors and to enter the correct information.

3. Trip Levels
UNDERFILL and OVERFILL TRIP LEVELS are entered through keypad entries. When the TRIP LEVEL key is depressed the display shows the current setting. A new inspection level can be entered through the Data Entry keys.

4. Rejection Selection
The Gamma 101P can monitor, or monitor and reject. Use of the EJECT ON and EJECT OFF selectors controls the reject signal. When EJECT ON is selected, underfills, overfills and containers that failed optional inspections are rejected. Through use of the SPECIAL FUNCTIONS key, the rejection of one or all inspection parameters can be overridden.

5. Inspection Parameters
The keys for INSPECTION, DELAY and DWELL TIMES control the time of inspection and the rejection. Inspection time will vary with the size of the container and the line speed. (For variable line speeds, the Auto Variable Speed Adjust option automatically resets the inspection time and other critical settings to maintain continuous inspection). Optimal DELAY and DWELL TIMES are calculated to millisecond accuracy to insure accurate, repeatable reject operation.

6. Special Function
The SPEC FUNC keys allow the user to enter a number of routines and displays that are not required on a regular basis. These include system set-up tools and inspection requirements.

7. Radiation Count
Depressing RAD COUNT will cause the display to show the radiation count which is updated every second for the most recent inspection.

Inspection Options
The Gamma 101 Fill Level Monitor inspection options include: Missing, Cocked or High Cap, Missing Foil and Tamper-Evident Band placement.

Cost Effective System Integration
The Gamma 101 readily integrates with any of PECO's automatic sampling, “dud” detection, vacuum/pressure monitoring or container inspection systems. When PECO's flexible ejector or diverter systems are in place downstream; integrating multiple inspection systems reduces cost and space requirements

High Speed, “Quick Change” and Heavy Duty Ejectors and Diverters Offer the Flexibility to Handle any Size Container.
PECO offers a full range of conveyor or pedestal mounted ejectors and diverters for efficient removal of any size container, case or tray at full line speeds.

PECO's “Quick Change” Ejector and Diverters minimize the time required for changeover on multi-product lines. Changeover time is reduced even further when a “Quick Change” Diverter is employed in combination with the automatic height adjustment assembly available as an option on PECO’s inspection equipment

Easy to Set-Up and Use
The Gamma 101 inspection unit features an easy to use “touch” sensitive keypad and easy to see vacuum fluorescent display for data entry and retrieval. The keypad and display are mounted on the all stainless inspection unit enclosure or on a remote terminal when the inspection unit must be mounted close into machinery or an area where space is limited.

Statistical Process Control (SPC)
The Gamma 101, like PECO’s other inspection, monitoring and ejection or diversion systems, offers the option of providing inspection or rejection parameters and results via a serial interface to a host PC. Data can be logged and printed, and reports provided on demand or at regular intervals. Tracking performance over time can forecast maintenance and in effect reduce down time and repair costs.
