Calibration of mechanical measurands

High-precision and modern measuring equipment ensure traceable and manufacturer-independent calibration of your mechanical test equipment. Both ISO/factory calibrations and calibrations recognised according to ISO/IEC 17025:2017 are possible.

In order to maintain quality and safety standards, it is of fundamental importance that you can rely on the results of the measuring equipment used. Here we are at your side.

The determination and monitoring of the prevailing pressure plays an outstanding role in many areas. In our in-house laboratories we can offer you accredited calibrations according to DIN EN ISO/IEC 17025/2018 up to a pressure of 1200 bar. Our laboratories are equipped with a wide range of primary, reference and working standards for this purpose. In addition, factory calibrations can be carried out with a pressure of up to 5000 bar. Our laboratory is based on two different types of reference: Pressure balances and pressure regulator. In addition, we have created the possibility of carrying out temperature-based pressure calibrations for up to 20 transmitters in our laboratory. Calibration is carried out in a temperature cabinet in a temperature range from -30 °C to 120 °C at -1 to 210 bar.

The sensitivity of pressure sensors deviate under dynamic input loads from purely static loads. In order to be able to guarantee real operating conditions in a dynamic application field also during calibration, dynamic pressure calibration is suitable. Our newly developed method enables true dynamic calibration of pressure sensors. The realization of traceable, dynamic pressure calibrations is unique since previous methods rely on static or slowly changing input signals.

Dynamic pressure calibrations are possible with our secondary calibrator in a measuring range between 20 bar and 300 bar. In parallel, the temperature can be controlled between 20 °C and 200 °C.

Bolted connections with firmly defined forces are indispensable in many industrial sectors.
ISO and DAkkS-accredited calibrations for your torque wrenches, screwdrivers and torque testers can be carried out on our specially equipped calibration systems with a measuring range from 0.01 Nm to 3,000 Nm in accordance with standard specifications.
Due to increasing demands for higher torques, we are able to carry out DAkkS-accredited and ISO/factory calibrations for your torque sensors such as torque measuring shafts and torque measuring flanges in a measuring range from 0.2 Nm to 5,000 Nm. On-site calibrations are also possible from 0.4 Nm to 5 kNm.

• Torque wrenches/screwdrivers according to DIN EN ISO 6789 or DKD-R 3-7
• Torque testers according to DKD-R 10-8
• Torque sensors according to DIN 51309:2022

With the help of our rotation angle test stand we are ideally equipped for the calibration of your rotation angle sensors and measuring systems, as well as torque and rotation angle wrenches according to VDI/VDE 2648 part 1 and 2.

In our laboratory in Dachau we have the possibility to carry out the combined DAkkS calibration of your rotary encoders with a rotational speed of < 0.2 1/min and thus belong to the top performers in this field. In principle, any measuring points between 0° and 360° with a measurement uncertainty of 0.06° (direct) or 0.5° (indirect) are possible. Take a look at our accreditation certificate.

A wide variety of force test equipment and force transducers must be calibrated at regular intervals. Testo Industrial Services features a force calibration device with a measuring range of up to 250 kN.

All common force test equipment and force transducers can be calibrated using our reference force calibration equipment, where the force is determined via the elastic deformation of a body. Calibration is performed by means of a comparative measurement; a high-precision reference standard ensures traceability.

You can also benefit from our expertise in the calibration of scales. We offer complete calibration for various types of scales, including precision scales, bench scales and platform scales up to 200 kg. For the highest requirements, we carry out DAkkS calibrations up to 80 kg directly on your premises. We also offer reliable calibration of hanging scales and spring scales up to 250 kN.

In industry, vibration forces act during various work processes, which are measured with the help of acceleration sensors. Our calibration service of accelerometers and vibration meters covers a wide and complex range of applications in almost all branches of industry. Here we offer manufacturer-independent DAkkS-accredited and verifiable (traceable) acoustic calibrations. Vibrations that occur during calibration are easily absorbed by our 2.6 ton sandstone table.

With our expertise we are available for secondary sine calibrations of vibration calibrators, vibration transducers such as monoaxial and triaxial sensors, vibration meters (in the frequency range from 0.2 to 20,000 Hz) up to special individual solutions for contactless vibration frequency counters or vibro-pads. Calibration is performed according to the principle of secondary comparison calibration in accordance with DKD-R 3-1 ISO 16063-21 (vibration calibration).

We offer you a full DAkkS calibration of almost all vibration test equipment, take a look at our accreditation certificate. In addition to calibration, we also offer the possibility to repair your recording devices in our service center in Hamburg as well as to adjust your devices according to manufacturer specifications in our laboratories.
