How does Taptone Leak sensors work? 

For closures with no measurable deflection Ac​oustic technology is used to measure pressure or vacuum in containers with metal closures that do not have a measurable lid deflection. Can be configured with an optional proximity sensor for cocked crown detection. Used primarily on metal crowns and ROPP closures.

How does TapTone Acoustic Sensors Work?

Acoustic technology is used to measure pressure or vacuum in containers with metal closures that do not have a measurable lid deflection. The sensor works by applying a “tap" to the top of each container lid using an electromagnetic pulse which excites the closure. The lid vibrates at a natural resonant frequency “tone" based on internal pressure or vacuum. The resultant “tone" signal is sensed by a microphone. The Digital Signal Processor (DSP) produces a real-time signal spectrum and calculates the resultant frequency of the “tone" for that lid. The frequency is then compared to user set limits. Containers with a frequency outside these limits are rejected.

Proximity Sensors

For metal closures with deflection Proximity technology​ measures pressure or vacuum in containers with metal closures by measuring the lid deflection. Used primarily for canned products or metal button up lids. Also available as Twin Proximity sensor​ for easy open pull tab cans.

How does TapTone Proximity Sensors Work?

Proximity technology measures pressure or vacuum in containers with metal closures by measuring the lid deflection. The sensor produces a continuous magnetic field that monitors the distance between the sensor and the metal lid. The continuous signal is digitally sampled to produce a merit value of the lid profile. The profile value is then compared to user set limits. Containers with lid deflection outside these limits are rejected.

Twin Proximity Sensors

For low/no vacuum bi-metal EZopen can ends Detects low vacuum and no vacuum steel cans with EZopen can ends (pull-tabs) at production line speeds up to 525 feet per minute.

 How does TapTone Twin Proximity Sensors Work?

The system is designed with twin proximity sensors​ suspended over the customer's existing conveyor system. As the can passes through the system, with the pull-tab in different orientations the twin proximity sensors scan the EZ open can end and measure the can lid deflection on each can. Signal processing is performed using the latest in high speed DSP (digital signal processor) technology. The signal processor is controlled by our PC software user interfaces​ with Ethernet capabilities for high speed streaming data or system monitoring and control. Our high speed proximity sensors provide accurate measurements at speeds up to 2000 CPM.

Compression Sensors (C)

Compression technology detects and rejects leaking and damaged flexible containers.  Used to test non-pressurized plastic containers for leaks. The sensor is available in standard or low profile configurations.

How does  TapTone Compression Sensors Work?

Compression technology detects and rejects leaking and damaged flexible containers. As a container passes through the system, dual parallel belts apply force to the sidewalls of the container. This action compresses the headspace of the container which allows a sensor to take a force measurement at the discharge of the system. Utilizing DSP technology, the controller analyzes the measurement and assigns a merit value to each container. If the merit value is outside of the acceptable range, a reject signal activates a remote reject system.

Dual Compression Sensors (DSC)

The TapTone DSC sensor can inspect a wide variety of flexible containers for micro leaks.  The design incorporates our patented dual sensor technology and is available in standard or low profile configurations.

How does Dual Compression Sensors Work?

Dual Sensor Compression technology detects and rejects leaking and damaged flexible containers at production line speeds up to 300 feet/minute (1.5 meters/second). The system is designed with dual parallel belts suspended over the customers existing conveying system. As the container passes through the system, the dual parallel belts apply force to the sidewall of the container. This action compresses the headspace of the container that allows a comparative measurement to be taken at both the infeed and the discharge of the system.

Dual Compression Sensors – Twin Belt (DSC-TB)

The PRO Series Dual Sensor Compression Twin Belt (DSC-TB) sensor is patented technology designed to identify and reject leaking pouch style containers caused by defects in the seams or fitment closure.

How does Taptone Dual Compression – Twin Belt  Sensors Work?

The TapTone PRO Series Pouch Inspector system operates in much the same manner as the DSC. The patented system is designed with a dual pair of parallel belts for better handling and testing of pouches. The parallel belts apply force to the sidewall of the pouch increasing  the internal pressure of the pouch. A comparative measurement is taken between the infeed and the discharge of the system. The comparative measurement eliminates typical variations seen in the production environment (Fill Level, Product, Temperature, and Seal width).

Force Sensors (F)

The TapTone Force (F) system will detect leaks and low pressure in LN2 dosed and carbonated containers with internal pressure up to 3.1 bar (45 psi). Optional sensors can be added for additional inspections.

Force Stainless Sensors (FS)

The TapTone FS system will detect leaks and low pressure in LN2 dosed and carbonated containers and aerosol cans with internal pressure up to 11 bar (160 psi). The TapTone FS is manufactured with a stainless steel transport deck and reinforced frame for extra rigidity in high pressure applications.

How does Taptone Force Sensors work?

Force techn​ology​ is designed to find leaks and low pressure in LN2 dosed or carbonated containers. As a container passes through the system, dual parallel belts transport the container past a sensor that measures the tension on the sidewall of the container. This action allows the system to measure the pressure inside the container and automatically reject all containers that fall below or above the acceptable pressure range.
