about

The "Control and inspection" market constitutes a separate sector compared with other equipment and machinery used in the bottling plant industry. This market requires know-how, targeted solutions to changing marketing demands, constant capability to innovate and, last but not least, absolute world-wide reliability.

FT System S.r.l. was founded in 1998 and has become a leading supplier of container inspection and monitoring solutions.

Our reputation for quality, reliability and customer satisfaction has made us the preferred supplier of inspection equipment to many of the leading manufacturers and system integrators in the food and beverage industry.

Since our inception we have grown to become a global leader in inspection and control solutions with more than 3,500 installations in over 60 countries around the world.

FT System, in order to ensure the quality of your products, using a large range of different technologies. Each technology has its use within our controls / inspectors, developed and optimized for maximum reliability and accuracy, targeted to the specific inspection to be conducted.

The main technologies used...

HF - HIGH FREQUENCY  
Used to measure changes in the fill level.

The system uses high frequency technology to detect changes in an electromagnetic field caused by variations in the fill level region of the container. As the container passes through the sensor the container acts as a dielectric and the electromagnetic field is altered. The change in the electromagnetic field is proportional to any variation liquid level.

RX - X-RAY
Used to measure changes in the fill level.

The system uses a low energy x-ray beam to measure the density of the product in the fill level region of the container. The X-ray beam passes through the container and is attenuated by the product blocking the beam. The amount of energy attenuated by the product is proportional to the amount of product in the fill level region. The X-ray beam is received by a linear diode array that measures the energy of the beam across the full width of the container. This analog data is used to calculate the fill level.

IR - INFRARED
Used to determine fill level and to backlight products when non-transparent to visible light.

The system utilizes a infra-red emitter/receiver with a wavelength tuned to the absorption band of water.
The infra-red beam penetrates the side of the container in the expected area of the fill level. A receiver is positioned on the opposite side of the container to detect the beam after it passes through the container. If the liquid is in the path of the beam, the infra-red light will be blocked.

SE - OPTICAL SENSORS
Used to detect the presence of elements such as caps, labels or in the detection of colour accuracy.

LS - LASER
The laser technology is also used for pressure measurement by means «Spectroscopy».

The system uses a tunable diode laser absorption spectroscopy technique. Certain molecules, when in the gaseous state, have a particular and unique frequency where they absorb light. This allows the measurement of the presence and quantity of a specific gas with an optical method. The laser emits a beam at a specific frequency on one side of the container and a receiver measures the beam after it has passed through the headspace of the container. The patented technology gives to perform the measurement independent of the colour or material of the bottle.

PX - PROXIMITY
Used to measure shapes and profiles distances in order to control positioning or pressure.

The system uses an inductive proximity sensor that measures the profile of the closure or can end. As the container passes through the system, the sensors takes multiple readings across the top of the can end or closure. These readings are combined and a profile of the can end or closure is generated. Containers with
internal pressure will have a convex profile and containers with vacuum will have a concave profile. Containers that have lost pressure or vacuum will have a wrong profile. The amount of internal pressure or vacuum can often be detected by the height of the convex profile on pressurized containers or the depth of the convex profile on containers with internal vacuum.
