RING SENSORS
(CLICK HERE FOR PDF PAGES)

Altech offers 3 types of Ring Sensors with different operating principles.
They have different features and advantages.

NORMAL SENSITIVITY RING SENSORS

They are Static Type Ring Sensors and their advantage is the ability to detect non-moving static objects. If metal is within its detecting range it generates a permanent output signal. Only when the metal object is removed the signal is deactivated. Due to the working principle the sensitivity is lower than on dynamic Ring Sensors.

Applications include Freefall applications to detect the presence of metal objects, count metal parts or ejection control in punching/ stamping applications, wire breakage and avoid unwanted metal objects in grinding operations. They are used for larger metal objects.

Features

  • Static Sensor Technology
  • Robust Aluminum housing
  • 10-30VDC supply
  • Various Ring Diameters 50-300mm
  • Complementary NO/ NC output

HIGH SENSITIVITY RING SENSORS

They are Dynamic Type Ring Sensors and generate a short signal pulse when metal is detected within its detecting range. Only moving metal objects can be detected. Sensitivity on dynamic Ring sensors is higher than on static type sensors. Therefore smaller objects can be detected.

Applications include Freefall applications to detect the presence of metal objects, count metal parts or ejection control in punching/ stamping applications, wire breakage and avoid unwanted metal objects in grinding operations. They are used for much smaller metal objects than the normal sensitivity Ring sensors.

Features

  • Dynamic Sensor Technology
  • Robust Aluminum housing
  • 0.6mm sensitivity
  • 11-30VDC supply
  • Various Ring Diameters 50-300mm
  • Complementary NO/ NC output

ULTRA HIGH SENSITIVITY RING SENSORS

Ultra High Sensitivity Ring Sensors work different than standard metal sensors. Their system is based on 3 coils. This allows the end user to analyze signals precisely. It is possible to differentiate different targets and draw conclusions on their origin.

Applications include all of the above, but Ultra High Sensitivity Ring Sensors are used primarily for the detection of very small particles in bulk material (Pharmaceutical products, Food and animal feed, granulated polymer materials, etc…).

Features

  • 3 coil system
  • Robust Aluminum housing
  • 0.2mm sensitivity
  • Including stainless steel control unit for Signal Analysis
  • Various Ring Diameters 25-100mm

MODULAR FLAT PACK SENSORS

Altech Modular Flat Pack Sensors are used on conveyor belts and chutes to detect all types of metal in the material being handled. They are used for quality checks and machine protection. Other applications include counting of objects and completeness checks.

 Features

  • Most Flexible and Modular System
  • Dynamic output for highest sensitivity
  • 1 and 10 Channel Control Unit
  • IP65

FLEXIBLE SYSTEM

The Flat Packs are available in 3 different sizes, all of which can be lined up with one another. This makes it a simple matter to create the required detector width from 3 standard elements. The width can also be changed at a later date when using the system. Control units are used to evaluate the signal from the flat packs.

SP Series Flat Sensors

Altech SP Series Flat Sensors are used on conveyor belts and chutes to detect all types of metal in the material being handled. They are used for quality checks and machine protection. Other applications include counting of objects and completeness checks.

Features

  • Various Width available
  • No Metal Free Zones necessary
  • Stable and Shock proof
  • Aluminum housing
  • IP65
  • Sensitivity adjustable via control unit

FS Series MULTI-CHANNEL Flat Sensors

Altech FS Series Flat Sensors are high Sensitivity Flat Sensors which are not only detecting smallest metal pieces, they are also capable of localizing them. They are mainly used in Recycling Industry Applications. It allows the user to separate metallic particles precisely from other parts. It can be used on conveyor belts, slides or free-fall applications.

 Features

  • Various width available (50-2,000mm)
  • Various resolutions, channel sizes
    (12.5-100mm)
  • No Metal Free Zones necessary
  • Stable and Shock proof
  • Aluminum housing
  • Interface fro PC or PLC
  • Sensitivity adjustable via control unit

BD Series TUNNEL Sensors

Altech BD Series Tunnel Sensors are used where highest detection capacities, sensitivity and reliability are needed. The user can choose between different control units depending on the complexity of his application. Applications include conveyors in the Plastic and Recycling Industry. The stainless steel housing also allows installation in the food industry. The unit is maintenance and calibration free.

Features

  • Highest Sensitivity
  • Custom Size (Height and Width)
  • Stainless Steel Housing
  • Different Control Units
  • IP65

TU Series TUNNEL Sensors

Altech TU Series Tunnel Sensors are used where highest detection capacities, sensitivity and reliability are needed. The user can choose between different control units depending on the complexity of his application. Applications include conveyors in the Plastic and Recycling Industry. The stainless steel housing also allows installation in the food industry. The unit is maintenance and calibration free.

The difference to the BD series is it is possible to be disassembled. It can be used on existing conveyors and machines which can't be disassembled. The Tunnel sensor can be divided into several modules and reassembled around existing machinery.

Features

  • Possible to Disassemble
  • Highest Sensitivity
  • Custom Size (Height and Width)
  • Stainless Steel Housing
  • Different Control Units
  • IP65
