ABTRONIX B.V. is organizing and hosting a unique free Calibration Seminar, March 22, 2017

This seminar provides the latest information, knowledge and skills for identifying the elements of an effective calibration system; understanding the requirements for those supplying calibration services; preparing for compliance and improving and utilizing measurement data focusing on continuous improvement and cost reduction.

This seminar will be hosted by Mr. J. Bailey. He has many years of experience in CALIBRATION. Transmille worked year to year to provide unique equipment and software for not only their own laboratory but to benefit calibration laboratories and manufacturers across the globe. If you (or your colleagues) are interested to attend this unique seminar please register before March 15, 2017 to If you are not able to attend, but interested in a demonstration at your site, feel free to ask.




Kvaser Intermediate-level Memorator now available

The Kvaser Memorator 2xHS v2 (00821-2) is now in stock. This dual channel CAN bus interface and standalone datalogger is an intermediate performance CAN interface and datalogger that connects to a PC via USB when in interface mode, and logs data to a standard SD card in logging mode. Triggers, filters etc. can be set on the Memorator 2xHS v2 via a user-friendly configuration program and stored on the flash disk.

Sitting between the
Kvaser Memorator Light (00513-6) an easy-to-use single channel data logger with no preconfiguration required and the Memorator Pro 2xHS (00819-9), which has advanced trigger and filter options and the ability to run user-developed scripts, the Memorator 2xHS v2 is an evolution of the Memorator 2xHS (00175-6), offering greater timestamp resolution and galvanic isolation.






Data Physics Acoustic Testing

An acoustic test, or acoustic testing, has changed over the years. Octave and fractional octave bands have been used for several decades now in the characterization of acoustic energy in various applications. Early acoustic analyzers were essentially comprised of analog filter banks. Band filtered data resulted in fewer numbers, making data easier to pass around before the advent of powerful PC-based systems that we are accustomed to today.


Standards developed for acoustic testing and acoustic applications were therefore based on filtered data, and this has largely resulted in the need for continued analysis using true filtered octave and fractional octave analysis. Practically speaking, however, the human response to noise and vibration is very non-linear in nature and most mechanical systems have a behavior that is best characterized by proportional bandwidth analysis.


Noise measurements are largely attempting to qualify sound as perceived by the human ear, which does not have a uniform linear response. Frequency weighting of the signal is common. The A-Weighting filter applies a frequency weighting that has been slow to correlate very well with subjective response. Every SignalCalc Dynamic Signal Analyzer is an acoustic analyzer capable of acoustic testing that involves evaluating sound power and applying weighting functions.


There are many different forms of airborne acoustic testing including general level recording, sound pressure spectral measurement, realtime octave sound pressure measurements, sound intensity, sound power, and sound quality.

Explore these applications in more detail to understand how SignalCalc Dynamic Signal Analyzers can help with acoustic testing and noise and vibration analysis:

Underwater acoustics involves generating signals and making measurements underwater. Making measurements with arrays of towed hydrophones, simple underwater R&D experiments, and generating underwater signals are all capable with Data Physics products. Learn more about Underwater Acoustics.


High Intensity Acoustic Power Generation is commonly used for simulated high energy levels seen at blast off, in-flight, and rocket fire conditions. Cutting-edge aerospace facilities and military facilities use these techniques for environmental survivability and qualification tests.

AIM-TTi MX180T and MX180TP added to the MX Series


The MX180T is a 378 Watt precision programmable laboratory power supply offering two full performance outputs and a third lower power output. Power sharing means that, as well as being able to output 180W + 180W + 18W, by disabling output 2, output 1 can become a 360W output. Range switching extends the capabilities so that outputs can be set to 15V/20A or 120V/3A or a range of other combinations for maximum versatility.

The MX180TP has all the same features as the MX180T but adds remote control via USB, RS232, GPIB and LXI compliant LAN interfaces

  Three high performance outputs each with full functionality

  Range switching gives variable voltage/current combinations

  Shared power mode provides double power from a single output

  Low output noise and ripple via linear final regulation

  High setting resolution of up to 1mV and 0.1mA

  Variable OVP and OCP trips on all outputs

  50 setting memories per output plus 50 linked memories

  Selectable voltage tracking (isolated tracking)

  Selectable current meter averaging

  Switchable remote sense capability

  Graphic LCD provides simultaneous output metering

  Numeric or spin-wheel control of all parameters

  Individual or combined output on/off control with

  programmable delay sequencing.

  3U half-rack case for bench or rack mounting

  GPIB, RS-232, USB and LAN (LXI) interfaces (-P models)

  Duplicate power & sense terminals at rear (-P models)

MX100T and MX100TP:

  315 watts total power

  Three outputs of equal power, each capable of 35V at 3A

  Range switching provides up to 70 volts and up to 6 amps

MX180T and MX180TP:

  375 watts plus of total power

  Two high power outputs plus one low power output

  High power outputs each capable of 30 volts at 6 amps

  Range switching provides up to 120 volts or up to 20 amps

  Low power output provides up to 12 volts or up to 3 amps

DJB Instruments How Critical is Accelerometer Cross Axis?

The simple answer is very!! The next question is how many engineers and accelerometer users know what it is?......

We will let you answer that yourself!! For those that want to consider it, heres a few good questions to ask

Cross axis diagram

Cross Axis is the effect of a vibration input to an accelerometer from a direction perpendicular to the measurement axis, i.e.


What does this mean for the user?

Every 1% of cross axis is a 1% error in your data, so a 5% maximum error for a new accelerometer is a maximum 5% error in your data.


How do accelerometer manufacturers control cross axis?

By pre-polarising the piezoelectric sensing material to operate in the primary measurement axis, however this is not 100% perfect.


What happens to pre-polarisation?

It degrades due to age, temperature and use, so inevitably cross axis will deteriorate and errors will increase.


What can I do to minimise errors?

Always have the cross axis checked during the annual calibration, otherwise errors can accumulate to exceed 30%


How do DJB control Cross Axis?

The Konic Shear design which is unique to DJB, has a natural cross axis cancellation due to the nature of its design, coupled with pre-polarisation it gives long term cross axis stability, unrivalled by any other accelerometer on the market today.

 djb konic      Cross axis diagram 1

As the mass acts on the Konic Shear element in cross axis it has an equal cancelling reduction action on the opposite side of the Konic element, with a fully radial design this ensures very effective cross axis cancellation.


If you have a challenging application that would benefit from high temperature accelerometers or have a new requirement looming please get in touch, the more information we have about requirements the better we are placed to develop the right solutions.
