TESA  Optical     Probe systems

 TESA S.A., part of the HEXAGON Group, offers one of the world’s largest ranges of metrology equipment with the aim to provide the “Complete Metrology Solution”. The TESA branded products, manufactured in Switzerland, includes over 4000 items in its range.  This includes products for the shop floor, inspection room, and calibration laboratory.

 The product portfolio has expanded considerably over time, and to compliment the range of traditional hand tools (micrometers, bore gauges, indicators), TESA offers digital height gauges, CMMs, Profile round part inspection systems, optical gauging systems, and calibration equipment.

 Products include

Micrometers, callipers, bore gauges, dial gauges etc

PRODUCT CATEGORY examples

 

Height Gauges:
Tesa Micro Hite 350/600/900  - Micro Hite Plus M 350/600/900 - Micro Hite 100 - Tesa Hite & mHite

These exceptional characteristics offer the most attractive PRICE-PERFORMANCE ratio on the market and make it an essential instrument for the workshop.

  • Large measuring span

  • Electronics completely protected against liquids or dust penetration

  • Built-in air cushion, and fixed panel

  • Automatic diameter measurement using TESA’s patented system which determinates the culmination point

  • Parallelism and perpendicular measurements

  • TESA opto-electronic measuring system (patented)

  • Compatible with TESA MICRO-HITE accessories, including measuring inserts and holder

  • SCS calibration certificate delivered with each instrument

 

 

Tesa Scope Profile Projectors:

(355H / 300V / 500V)

Calibration equipment:  (UPC /UPD / POLO)

Optimally suited for inspecting parts having a flat surface as well as components used in the micromechanics

Main advantages

  • Profile projector with vertical light illumination.

  • 360° rotary frosted glass screen having a 300 mm diameter.

  • Crossline reticules 30°, 60° and 90°. Also with 4 overlay chart clips.

  • Fiber optic surface illumination. Profile illumination with green filter included:

  • Enhances image contrast, makes measurement easier and reduces all effects due to the operator.

  • Automatic shut down of the bulbs when the projector is not used for a few minutes
    (thus increasing the life of the bulbs by 5).

  • Measuring table with crosswise displacement

  • 200 x 100 mm (X/Y)

  • Patented TESA vision system

 

Tesa Visio 300 Vision System:
Ø Manual with Vista software or PC-DMIS software
Ø DCC with PC-DMIS software

Manual machine versions

These two versions have a coordinate stage fitted with a quick release system in both axes X and Y. This system enables fast displacements for locating the geometric feature to be measured.

Dis-engageable wheel drives are used for quick motion in the Z-axis as well as fine setting of the focal length.

DCC machine version

On this version again, the coordinate stage along with the vertical axis are displaced by means of  DC servomotors. Their speed is tightly controlled through the rotating encoders, especially when the joystick is used or high precision images are processed in the X-direction. This for example.

A plain axis coupled with planetary arranged ball bearings allows the stage to be displaced mechanically. This system also acts as coupling clutch in case of collision.

Vertical displacement is ensured by rack and pinion.

 

Tesa Scan 25 & 50 CNC non-contact round part measuring system

All dedicated TESA SCAN and Profile systems for non-contact measurement incorporate high-resolution CCD linear sensors. Each sensor is subdivided into thousands of light sensitive pixels (DIN 32877).

When the part image is projected, these sensors, which act as light sensitive rulers, can detect the slightest changes at sub-pixel level. The workpiece is illuminated with parallel white light and its image is projected onto the linear CCD sensors.

These sensors provide the information obtained from the image, which allows accurate analysis of the geometry of the part features.

Rugusurf 10G

The very latest portable surface roughness gauge from TESA. Being compact and versatile, this gauge can

equally be used for incoming or surface finish inspection on the shop floor or in the measurement laboratory.

Among other benefits, the tool will measure roughness parameters to ISO 4287:1997, DIN/ISO 2085:1998,

MOTIF or CNOMO standards.

 

 

Micro Hite 3D:  Manual co-ordinate measuring machine with Reflex controller

The concept

This latest release from TESA was to be the response to three relevant sales arguments:

– Be accessible to all.

– Provide the solution to every metrology application.

– Offer the best price/performance relationship. With their today’s ability to produce series of features

integrating advanced technology, TESA have designed and manufactured all guiding parts along with the probe heads, whether manual or motorised, besides a full range of top-quality accessories. Thereby, the company could fulfil its goals in terms of performances and manufacturing cost control.

 

Respected brands within the TESA portfolio include Mercer, Etalon, Roch and Interapid.
