Calibration of dimensional measurands

In our dimensional calibration laboratory we calibrate your length measuring equipment with the highest precision. These include indicating test euqipments, measuring standards, test euqipments and angles.
 

In order to ensure the measurement results, our premises are air-conditioned to a temperature of 20 °C ± 1 K. This ensures standard-compliant and reliable calibration in our dimensional laboratories. For the calibration of test equipment blocks, even rooms with a temperature range of 20 °C ± 0.5 K are available.

Characterized by a high number of calibrations per day, many processes are optimized and automated in order to relieve the time-consuming manual calibration process.
Our laboratory has a fully automated measuring robot, which calibrates calipers for you within a very short time, with very low measurement uncertainties. In addition to the normative calibration scope such as external, internal, depth and step measurements, the light gap tests and ease of movement tests are also carried out fully automatically with the calibration robot, thus relieving the manual calibration process.

For the calibration of thread rings and thread mandrels, several thread scanners are used in order to be able to make statements on the pitch and flank angle in addition to the usual pitch diameter. For the area of dial test euqipments, several fully automatic dial test euqipment test stations are in use, which determine process-reliable and reproducible measured values via a camera system without operator influence. Furthermore, we are optimally equipped for the calibration and measurement of your individual workpieces, test euqipments, assemblies and much more.

Furthermore, our long-standing exclusive partnership with the manufacturer Keyence distinguishes us. This gives you the opportunity to carry out accredited calibrations of optical measuring instruments directly at your premises with minimum downtime.

Our innovations

Measuring robot for calipers

The vernier caliper is one of the oldest testing devices in industry. Due to the high number of calibrations per day, many processes are optimized and automated in order to relieve the time-consuming manual, very operator-dependent calibration process.

Our laboratory has a fully automated measuring robot, which calibrates calipers for you within a very short time, with very low measurement uncertainties. In addition to the normative calibration scope such as external, internal, depth and step measurements, the light gap tests and ease of movement tests are also carried out fully automatically with the calibration robot up to a measuring range of 300 mm.

Calibration of calipers in the fully automated measuring robot

At our measuring robot for calipers we are specialized in the following test equipment:

  • Vernier caliper
  • Caliper with numerical display

Dial test equipment test station

The dimensional laboratory of Testo Industrial Services has several fully automatic dial test equipment test stations.
The dial test equipment test stations are characterized by a process safe camera reading. This enables the calibration of analogue and digital dial test equipment and many other indicating test equipment up to 100 mm in shortest processing time and with highest precision.

Test station for the calibration of dial gauges

At our dial test equipment test station we are specialised in the following test equipment:

  • mechanical and digital dial test equipments
  • Fine pointer
  • Lever test equipments
  • Incremental probe
  • Inductive probes

Horizontal linear encoders

Several horizontal linear encoders with a maximum length of up to 1000 mm for external measurements or up to 800 mm for internal measurements are used in the dimensional laboratory of Testo Industrial Services as reference measuring equipment for the calibration of length and dimensionalstandards.

Our qualified personnel carry out the calibration of cylindrical and tapered external, internal and thread measurements.

At our length measuring devices we are specialized in the following measuring devices:

  • cylindrical and tapered plug test equipments
  • cylindrical and tapered ring test equipments
  • cylindrical and tapered thread plug test equipments
  • cylindrical and tapered thread ring test equipments
  • Test pins
  • Adjustment dimensions
  • Feeler test equipments

Angle and degree measuring station

Straight edges and 90° angles are mostly used in manufacturing and control areas of companies. Measurements to directly check the product quality are commonplace. Therefore, regular calibration of this measuring equipment is crucial. A specially developed calibration device on a hard stone plate ensures the highest accuracy during calibration.

At our angle and degree measuring station we are specialised in the following measuring instruments:

  • 90° stop and flat angle, hair angle
  • Straight edge
  • Flat rulers
  • Angle standard

Test equipment block test station

Parallel test equipment blocks are mostly used for checking calipers, outside micrometers, dial test equipments or as high-precision measuring standards. To ensure that the measuring equipment provides representative and reliable measured values, regular calibration of these test equipment blocks is recommended. Testo Industrial Services, as a recognised calibration laboratory, has the competence and the corresponding accredited test equipment block test stations.
We calibrate for you in conformity with standards according to VDI/VDE/DGQ 2618 sheet 3.1 in a measuring range from 0.5 mm to 150 mm.

At our test equipment block test station we specialize in the following measuring instruments:

  • Test equipment blocks in steel
  • Test equipment blocks in ceramics
  • Test equipment blocks in tungsten carbide (carbide)

Tape measure test station

The tape measure test stations in the dimensional laboratory of Testo Industrial Services give you the opportunity to have your tape measures, folding rulers, scales, draw wire sensors etc. calibrated by us. Any length up to 100m can be calibrated by sectional testing. A conversion device also allows the linearity of potentiometric displacement transducers to be determined.

At our tape measure test station we are specialised in the following measuring instruments:

  • Tape measures
  • Folding rulers
  • Roll tape dimensions
  • flexible steel rods
  • Working scales
  • Line scales

Displacement sensors

At our displacement sensor measuring station we calibrate your displacement cable sensors, rod potentiometers and laser triangulation sensors. As the number of electronic displacement sensors increases, the individual test positions are approached fully automatically with a linear motor axis at high speed in order to determine the linearity of the sensors according to the respective manufacturer's specifications. The axis has a total travel of 1200 mm and a highly accurate electronically controlled positioning for approaching the individual measuring steps.

At our displacement sensor measuring station we are specialised in the following measuring devices:

  • potentiometric draw-wire sensors
  • Rod potentiometer
  • Laser triangulation sensors

Thread scanner

In the industrial environment, a tightly fitting screw connection is unavoidable. Many thread types and diameters are used. In addition to the simple pitch diameter, which is often tolerated by standards, other parameters such as the pitch, the flank angle, but also the core or outer diameter can be decisive for a tight and secure threaded connection.
We at Testo Industrial Services calibrate a large number of your thread ring test equipments or taper thread ring test equipments with our thread scanner. High-precision contour scanning of the entire thread profile enables process-relevant statements to be made.

At our thread scanner we are specialized in the following measuring devices:

  • Thread ring test equipments
  • Thread plug test equipments
  • Taper thread ring test equipments
  • Taper thread plug test equipments

Measuring microscopes

Many test equipments are often flat, sensitive or small and can only be measured tactilely by probing to a limited extent. Optical measuring microscopes, on the other hand, often reveal things that can only be guessed at by the human eye.
With our long-standing and exclusive cooperation with the measuring instrument manufacturer Keyence, Testo Industrial Services ensures the accuracy of your optical measuring instruments and, in addition to the calibration and adjustment programs agreed with the manufacturer, also carries out accredited calibration directly on your premises.
