Features of Paper/ Board Burst Tester
Bolt-on Diaphragm Mounting
The Bolt-on Diaphragm Mounting technique of the Burst tester eliminates the diaphragm from twisting during installation. Once the diaphragm is in place, the upper plate is secured to the lower device. This secure lock-down eliminates the potential of the diaphragm loosening during use, which can occur with screw-on type mounting brackets.
Silicon Oil
The silicon oil utilized in the PROFILE/Plus Burst has a longer lifespan than other hydraulic fluids and does not break down and leave deposits or gumming in the instrument. In addition, the silicon oil’s viscosity is such that air bubbles that get into the fluid quickly rise to the surface, where they can be removed.
Adjusted Burst
Each diaphragm has its own unique expansion characteristic that changes with the age and usage of the diaphragm. To eliminate this variable from the bursting strength measurement, the PROFILE/Plus Burst offers the Adjusted Burst capability. The expansion characteristics of the diaphragm can account for a large portion of the bursting strength in low bursting strength samples. Taking this in to account can provide a more accurate burst assessment.
Continuous Monitoring Technique
Accurately capturing the point of rupture requires continuous monitoring of the measurement cycle. To accomplish this, the PROFILE/Plus Burst incorporates an innovative technology that provides maximum instrument resolution. As fibres begin to break in the sample, a premature point of rupture can occur. The PROFILE/Plus Burst is able to move beyond this first point and determine the true point of rupture, by using this continuous monitoring technique.
Improved Diaphragm Design
The diaphragms used in the paper version of the PROFILE/Plus Burst instrument are made with a transparent polymer. This allows for easy determination of any entrapped air, as the diaphragm is located at the zenith of the diaphragm= mechanism. Any entrapped air will rise to the highest point and will be easily seen and then eliminated from the hydraulic chamber.
Selectable Clamping Pressure
If the sample to be tested is not properly clamped there is a high potential of introducing inaccuracies into the data. To ensure proper clamping of the sample the PROFILE/Plus Burst provides the capability of adjusting the sample clamping pressure. Establishing proper clamping pressures for grade differences is important for achieving maximum repeatability and reproducibility in your quality program.

Frequently Asked Questions (FAQ)
What industry standards does the Technidyne PROFILE/Plus Burst comply with?
The PROFILE/Plus Burst is engineered to meet several international testing standards, including ISO 2758 (Paper), ISO 2759 (Board), TAPPI T403, and TAPPI T807. This ensures your quality control data is globally recognised and compliant with manufacturing specifications.
Can this instrument test both the top and bottom sides of a sample?
Yes. The PROFILE/Plus Burst is capable of fully automated measurements for both the top and bottom sides of the material. This provides a comprehensive profile of the sample's strength characteristics in a single automated sequence.
How does the "Continuous Monitoring Technique" improve measurement accuracy?
Standard testers may stop at the first sign of fiber breakage, leading to premature readings. Technidyne’s Continuous Monitoring Technique identifies the true point of rupture by moving beyond initial surface failures, providing the highest resolution and most accurate burst assessment available.
Is the PROFILE/Plus Burst compatible with automated laboratory systems?
Absolutely. It is "PROFILE/Plus Automated Testing System Ready," meaning it can operate as a standalone unit or be integrated into a larger, multi-instrument automated testing line to drastically increase lab throughput and reduce labor costs.
Why is silicon oil used instead of standard hydraulic fluids?
Silicon oil has a significantly longer lifespan and does not break down into deposits or "gum up" the internal mechanisms. Its specific viscosity also allows air bubbles to surface quickly for easy removal, ensuring the hydraulic system remains precise and maintenance-free.
