By today’s available computational methods, such as the finite element method, stress test calculations are now mainly carried out on the computer. Nevertheless, photoelasticity is a good and rapid…
Photoelasticity evaluates stress of models or components made of transparent birefringent plastics by polarisation optics. The loaded model will be investigated between crossed polarizing filters.…
There are nine types of films with their specific ranges available to cover the measurement range of 0.006 to 300 MPa. The latest type "Ultra Extreme Low" covers the range from 0.06 to 0.5…
Calibration Device EV 208 with Elastic Modulus Measurement Tool
In the calibration device EV 208 a prismatic test bar with rectangular cross section is loaded with a pure bending moment of 8 Nm.…
The ring dynamometer consists of a special shaped elastic steel ring attached with two facing drawbar eyes, pressure seats or threads. A load on the ring leads to a slight deformation, which is…
Choice of Measuring Range The ring dynamometers are available with various methods in execution. Depending on the design the measurement range lasts from 50 N up to 200 kN. The universal…
The use of the heat distribution film Thermoscale varies similar to the Prescale pressure measuring film. Applications for sealing plastic bags, laminating, heat seals, PCB or solar panels, nip…
Principle and Evaluation
The 90 micron thick single temperature film may be similar used as the pressure sensitive film. Cut with scissors it is placed between the body to be tested. Within the…
Measurement Range
For the measurement range of 60 to 210 °C Tiedemann provides three different heat flow films. The Thermoscale 100 for 70 to 105 °C, the Thermorex 150 for 100 to 150°C and the film…
