 MTS 3D ORM Autofocus FBRM patent Signal-lens technique



Version March 2016



MTS 3D ORM FBRM Signal lens technique is a patented technology developed by MTS.


MTS 3D ORM Autofocus in combination FBRM Signal lens technique integrates forward, lateral and backward optical signals. Our  focal based <2°light paths angle reduce unwanted scattering light effects, so that detection quantity of back reflected lights will be doubled. Compare with single lens multi mode laser particle system size analyzer, this technique improves measuring range dramatically, measuring accuracy for fine particles and resolution ratio. Compare with MTS 3D ORM Autofocus FBRM Signal-beam laser particle size analyzer, the technique improves reliability and reduces failure rate under process condition.

The high tech Sapphire window surface prevents any fouling and contamination under process condition.

MTS Automatic alignment focus technique

Automatic alignment system developed by MTS itself is comprises the Autofocus motion, precise alignment into receiving fibre, signal shape controller and software system. The minimum starting point in front of the window is 2 micron, which guarantees that auto focus of laser beam is on the receiving 4 micron fibre centre all the time. Thus accuracy of test result is improved in a 124 Fraction size distribution. The automatic focus alignment system is equipped on all models of MTS 3D ORM
laser particle size analyzer, no matter it is an economic model with basic quality with low price, or it is a sophisticated intelligent PAT model including ISO 9001 validation with modular price structures. As it were, MTS 3D ORM Autofocus with automatic alignment system at the sensor operation side has become a standard feature for all models of laser particle size analyzer from MTS.

Unique MTS calibration technique for accuracy


All instruments are passed through the calibration by MTS reticular System. In addition different standard calibration sample, will guarantee the accuracy of the instrument's test results. Standard sample is provided along with the instruments at the same time. Users can check up the accuracy of the instrument at any time by MTS reticular System, which may avoid losses caused by inaccurate test results due to instrument relocation, voltage/photon/laser/damping fluctuation and other factors which can be found by internet link in connection with the MTS service team.



  • To ensure the accuracy of test result for 24 hour operation.
  • To ensure each instrument has good consistency of test results based on reticular validation quick check.

Reliable circulation & dispersion system is in general not needed - but available


The MTS Sensor is normally directly installed inside a reactor or up streaming piping system. Wet dispersion systems are normally not needed. Ultrasonic disperser can be directly engaged with the MTS 3D ORM Sensor System.

Based on the LIE which can be optional adapted between 1 and 30 mW MTS normally can operate in customer application fields.





  • It guarantees that all products which exist as a system in a formulation can normally measure samples can be fully dispersed.
  • Therefore we keep the habit of the original product.
  • Easy operation.
  • Agglomeration and soft artefacts can be observed under process condition like during fermentation.
  • It guarantees the repeatability and accuracy of test results without interference of possible agglomeration and soft artefacts



Dirt and contamination protection technique of sensor window and lenses


All models of MTS in production particle system in situ size measurement of particle analyzer are equipped with electrochemical polished sapphire windows based on the highest military optical standard contamination protection.

The inside sensor the lens systems and the optomechanical system can be protected optional by inert gas flushing for condensate and dirt



  • To avoid any damage or contamination to the optical systems
  • Reduce the number of instrument’s maintenance downtime, improve instrument’s utilization.


Automatic water suction technique and cost of treatment is not needed.


MTS in production particle system insitu sensor size measurement particle analyzers are directly in operation inside the media which should be analyzed!

Therefore MTS Sensor Systems does not necessarily need equipped with the water suction pump and water level measuring device, which can automatically pump the water in the bucket into the circulation tank for later treatment.

Measuring technique for operation under dew point temperature


For the MTS laser particle analyzer running in high humidity environment, the technique will play a big role in ensuring instruments run in the normal condition and accurate test results can be obtained. Because in high humidity environment, mistreat is easy to condense on the inside surfaces optics of the Sensor. The sensor must be purged under this condition with a clean nitrogen gas. If condensation accurse the MTS would go in a alarm status.



  • Give clear warning for condensation
  • Heated purge gas would also remove outside incrustation during cooling crystallization
  • nitrogen gas allows operation under explosion safety regulations
  • ATEX Zone 1 approval optional
  • To ensure the accurate and reliable results under hardest process conditions.
  • Safety automatic control by the system without possible failure by operator.



High-speed sampling signal technology


By adopting the Multi Capture Signal Technology (MCST) and high-speed AD technique, sampling rate of MTS’s laser particle analyzer can reach in the most sophisticated versions 250.000 captured signals per second.

So the system can accurately capture the back reflected signals of particles when they passing the Autofocus driven by the single mode 4 micron the laser beam, which avoids the distortion caused by out of focus area. MCST ensure the accuracy and repeatability of the result. High-speed signal sampling technique is particularly important in the dry powder application where the flow speed is high.



  • To improve the repeatability and accuracy of the size results.
  • To improve the analytical efficiency.
  • In process operation of up to 50 m/sec.
