Force reference standard machine 100 N-K-BNME
The core of the reference standard is a stainless and non-magnetizable mass stack, partly made of an aluminum alloy and partly of a special steel. partly made of a special steel. The lightweight load frame lightweight construction is made of an aluminum alloy. The machine frame has two cross beams, one each for tension force measurements and one for compressive force measurements. For environmental conditions, the measuring equipment is fully enclosed. the measuring device is completely enclosed. The measuring device is equipped with a force shunt control. Force shunts are indicated by yellow lights and, in the case of automatic measurement automatic measurement, the measured value is marked with an additional value is marked by an additional character in the measured value file.
Key Facts

- Expanded relative measurement uncertainty: 1-10-4 in the range 0.5 N to 100 N
Force reference standard machine 25 kN-K-BNME
The reference standard machine consists of a base frame and an overhead lever lever at the top, which is mounted in a strain-controlled manner. The short lever arm is 40mm and the long lever arm is variable, as the mass (running weight) can be positioned in the range of ± 1000 mm by means of a precision spindle. Positioning the mass in positive direction generates compressive forces, positioning in negative direction generates tension forces.

- Operating principle: Running weight on lever arm, elastic strain-controlled bearing
- Accredited measuring ranges: 1 kN to 25 kN (at any load level)
- Expanded relative measurement uncertainty: 2·10-4
Force reference standard machine 100 kN-K-BNME
The reference standard machine has two measuring ranges: The direct loading part consists of a mass stack made of stainless steel (19 times 250 N masses, once 150 N mass) and a load frame combined of aluminum and steel (100 N) and a combined tension-compression load beam. The transmission section consists of a 1:20 lever mounted via strain-controlled joints and a likewise combined tension-compression traverse.

Significantly less effort and cost efficiency with GTM standard adaption parts for calibration of large forces
Adaptation recommendation for force transducers, load cells, force measuring devices
For the calibration of large nominal loads, one needs the appropriate adaptations. However, their production is complex and expensive. That is why GTM, as your first choice calibration service provider, provides a remedy. In the GTM calibration laboratory, various standardized adaptation parts are available for calibrations in the range up to 10 MN. As a customer, you benefit with cost advantages up to the five-digit range. Please check if your calibration object is to be adapted Downloads of 3D PDF files can be found below for the corresponding variants. In them you can see the possible installation situations of the force transducers. With appropriate software (e.g. Adobe Acrobat Reader XI) you can also read dimensions from the drawings.
