Mechanical Timber Grader MTG
Mechanical Timber Grader for quick immediate determination of wood solidity / 
according to standard EN 14081-4:2009 / incl. data transfer and processing /
with bluetooth for wireless data transfer

The mechanical timber grader determines the solidity of wood within short time providing reliable results. Nowadays timber grader become more and more important. Since January, 1st, 2012 a new guideline was released in wood trade, so that a CE mark must be made on every wooden palette. This mark is based on the EN 14081-4:2009 standard. These guidelines follow the purpose to mark the quality of wood and their solidity with a grading code, in order to establish a transparent and comparable wood trade within the European Union. In addition to an internationally recognizable label the mechanical timber grader can also translate the measured data into various national-wide grading codes. Thus the results of the mechanical timber grader MTG can be transferred and sent to other countries. The mechanical timber grader is usually used by smaller companies that work with wood and want to quickly determine their timber grade by doing regular quality controls. But it is also . But the mechanical timber grader is also often used in sawmills and larger industries. Since the CE- certification has become obligatory the companies have to chose between automated and individual visual timber grading. In that process a handbook with the protocol of the timber grading must be written. With the mechanical timber grader this protocol can be generated almost entirely in an automatic process. Therefore the measured data  can be transferred from the mechanical timber grader to a laptop or computer via bluetooth. The handbook has to contain the following information: order number, job number, origin of wood, humidity class, dimensions, surface, humidity of dry timber. Thus a long-term protocol is made much more easy by the mechanical timber grader MTG, so that archiving the measured data for a period of ten years becomes much simpler. The mechanical timber grader MTG supports the option to measure the solidity of spruce. Further wood types can be provided on demand. For a mechanical timber grading and sorting it is crucial that the mechanical timber grader must have  non-destructive performance. The mechanical timber grader can be applied world wider, since it supports an internationally valid grading system. Therefore the licenses of the mechanical timber grader can be upgraded online.

The display of the mechanical timber grader is well-arranged while the results can be easily read

The mechanical timber grader operates quickly, showing within a short response time the measured data of soft- and hardwood.

The mechanical timber grader is device that is very easy in its operation, starting the measurements by pressing the yellow key trigger. 

Due its software the timber grader is ideal to determine the solidity of wood in an automated process and transferring the data in order to protocol it in a logbook.

Here you can see the entire software. This software supports a long-term protocol to archive for ten years.

Here you can see the measuring frontal of the mechanical timber grader, which is placed on the measured wood for grading.

Alternatives for timber grading

Besides the mechanical timber grader, that has an integrated sensor for the measurement, there are other alternative to determine the wood quality. But those are more time-consuming, complicated and the also cause damages on the wood. Those alternatives often require boring a whole into the wood, so the measurement must be performed on a sample, that might become useless for any further processing. But those samples cannot be always provided and boring a whole consumes time so that this way of timber grading might not be always applicable. The mechanical timber grader facilitates the grading of wood such much as it becomes much easier and actually applicable. In the following text alternatives of timber grading are explained. 
Determining the timber quality by measuring resistance during boring: Therefore the measuring device is placed onto the wood. A drill needle placed on the device's front bores a whole into the wood with a consistent force. Simultaneously the device measures the resistance of the wood to the drilling and saves those data. 
Determination of the wood quality with a shock system: This is a system which records the traveling time of an impulse wave that is caused by a shock. Therefore the impulse travels through the wood until it returns to the sensor and is recognized again. Every kind of wood has a characteristic reaction to sound, so that the solidity of the wood can be measured reliable. This allows consumptions about the wood's inner qualities.
