Sensor for precise thickness measurements                                                                          Product Technology

 

The new thicknessSENSOR opens up diverse application possibilities in terms of non-contact thickness measurement. The sensor operates with high precision and enables fast commissioning as well as ease of use.

 

The thicknessSENSOR is a fully assembled system for non-contact thickness measurements of strip and plate material. The system consists of two displacement sensors that are fixed opposite to each other on a frame and measure against the target from both sides. The material thickness is detected according to the difference principle and calculated using an integrated evaluation unit. The measurement values are output as analog values via voltage and current or in digital form via Ethernet. Due to its extremely compact size, the sensor can also easily be integrated into restricted installation space.

 

The intuitive web interface provides the new thicknessSENSOR with unique ease of use and enables the user to load individual presets for the respective measurement task. Up to eight user-specific sensor settings can be stored and exported in the setup management feature. The measurement task can be optimized using signal peak selection and freely adjustable signal averaging.

Class 1 laser sensors for fast and precise measurements

optoNCDT 1420 CL1 laser sensors are designed for increased laser class 1 security regulations. With this laser class, the radiated power is at max. 390µW, which is significantly lower than laser class 2. The optoNCDT1420 CL1 offers similar to the optoNCDT 1420 series a unique combination of speed, size, performance and application versatility for displacement, distance and position measurements. The compact triangulation sensor achieves a high measurement accuracy and measuring rates of up to 4kHz.

 
 

Use in automotive production

Especially in automotive production where people work in the vicinity to laser sensors, optoNCDT 1420 CL1 models are applied. The CL1 series satisfies the requirements placed by the automotive industry with respect to performance and laser class. Therefore, protective measures that correlate with conventional laser class 2 sensors are no longer necessary.

 

Measuring sensitive materials

Conventional laser class 2 sensors can cause undesirable reactions in medical and pharmaceutical engineering when measuring sensitive materials. Due to their reduced laser power, optoNCDT 1420 CL1 sensors measure sensitive materials such as substrates without causing any chemical or thermal reaction of the surface.

Inspection of the interior diameter of the extruder barrel

The idiamCONTROL sensor system precisely measures the inner diameter of bore holes such as in extruders in order to determine the wear. The idiamCONTROL is guided into the bore hole and determines the bore hole diameter while being pulled out. Wear-based tolerance violations are automatically displayed and can be output via USB.

 

Advantages

  •  Touchscreen with user-friendly software for fast evaluation directly next to the extruder
  •  Reliable measurement on up to 6 tracks
  •  Suitable for numerous extruder barrel dimensions from 32 to 180 mm diameter
  •  Diameter is directly displayed
  •  Automatic evaluation function via tolerance specifications
  •  USB interface for data output and logging
  •  Integrated function test for inspecting the condition of the measuring system
 
     
Measurement on all metals thanks to factory calibration   Easy and safe guidance directly via reinforced cable and spring-loaded rollers   Reduced service time for extruder maintenance   Targeted replacement of defective segments
 

Operating principle

The idiamCONTROL works with integrated capacitive displacement sensors. These measure the actual bore diameter over the whole length of the process part. As the axial sensor position is detected as well using a cable-length measuring system, deviations in diameter can be found quickly and reliably. In doing so, each sensor position is related to a diameter in the longitudinal axis of the bore hole. As a result, the diameter length profiles are provided in six tracks and with a spatial resolution of 1 mm. The wear is calculated from the respective diameter values using the evaluation software.
