Calibration of mechanical measurands

Testo Industrial Services is characterized by an extensive mechanical laboratory, specialized in the calibration of pressure, torque, angle of rotation, force and acceleration measurement technology.

High-precision and modern measuring equipment ensure traceable and manufacturer-independent calibration of your mechanical test equipment. Both ISO/factory calibrations and calibrations recognized according to DIN EN ISO/IEC 17025:2018 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.

Pressure

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.

Calibration of pressure gauges

In the field of pressure, for example, we are specialized in the following measuring devices:

  • Digital and analogue pressure test equipments: Additel 681; SIKA D2
  • Pressure test equipments with digital display: Testo 511, Greisinger GMH1100
  • Pressure transmitter with electrical output signal: Keller PA-33X; Kulite XTL-198
  • Pressure regulator: WIKA CPC6050; GE DRUCK Pace5000
  • Pressure calibrators: Fluke 719; Beamex MC6

Torque

Bolted connections with firmly defined forces are indispensable in many industrial sectors. Therefore, a traceable calibration of the torque wrenches used must be carried out for quality assurance reasons. Testo Industrial Services has the know-how and the equipment to carry out ISO and DAkkS accredited calibrations for your torque wrenches, torque testers and torque sensors according to normative specifications on our specially equipped calibration facilities for torque with a measuring range of 0.01 Nm to 1000 Nm or 3000 Nm:

  • Torque wrench/screwdriver according to DIN EN ISO 6789 or DKD-R 3-7
  • Torque transducer according to DIN 51309
  • Torque testers according to DKD-R 3-8
Calibration of torque measuring instruments

Rotation angle

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° are possible. Take a look at our accreditation certificate.

Calibration in the angle of rotation range

In the field of rotation angles , we specialize in the following measuring devices, for example:

  • Torque sensors with angle option: HBM T4WA
  • Torque wrench with protractor: GWK Quantec; SCS;Gedore E-Torc
  • Rotary encoder: Wachendorf

Force

The measurement of the respective force is indispensable for the forming of various components. This is the only way to manufacture products in a standardized manner and to ensure quality. Therefore, a wide variety of force test equipments 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 equipments and force transducers can be calibrated on our 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.

Calibration of force gauges

In the field of force, for example, we are specialized in the following measuring devices:

  • Force test equipments: Chatillon DFE II; Alluris FMI; Sauter FL
  • Strain test equipment force transducer: HBM U2B; Burster 8524; ME-Measurement Systems KM
  • Piezo force transducer: Kistler 9311B
  • Load cells/Hydraulic pressure transducer:Tecsis F1115

Acceleration

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.
