Dyna Desk – Test Bench

One testing environment across every machine we build. It closes the control loop, authors the method, acquires the data and issues the report — and its full specification is published here, machine by machine, in full.

software, every machine: One
closed-loop control modes: 4
data acquisition: upto 400 kHz
64-bit: Windows 11

One environment

The same software drives a universal frame, a fatigue rig, a torsion bench and both rheometers, so an operator trained on one is trained on all of them.

Methods, not scripts

Tests are built as methods — ASTM and ISO templates out of the box, or your own — saved, versioned and repeated exactly.

Measured, then proven

Every transducer identifies itself and carries its own digital calibration, so the number on the report is traceable to the cell that produced it.

Nothing held back

Results export to spreadsheet, PDF and CSV, and the full published specification for each machine is on this page, in full.

Control

Closed the loop, then made it programmable.

Four control modes, switchable inside a running test, and a wave maker that builds the loading history stage by stage instead of offering a fixed set of canned tests.

Four control modes

Travel, load, stress and strain, selectable per stage inside a single test rather than fixed for its duration.

Waveform authoring

Ramp, haversine, sinusoidal, hold, tapered and sweep sine, sequenced stage by stage into the loading history a part actually sees.

Follow Me

Push or pull the upper grip and the crosshead follows, harder meaning faster — the fastest way to set a specimen.

Safe Jog

Positioning stops the instant it senses force, which protects the load cell as much as the specimen.

Sample protection

While gripping, the crosshead moves to keep force on the specimen inside a set threshold, so a sample is not deformed before the test begins.

Fine position

Four jog speeds down to a thousandth of a millimetre, for delicate setups where the approach matters as much as the test.

Multi-axis control

Several axes under closed-loop PID at once, each offset in phase against the master axis.

Amplitude control

Demand is raised or lowered against the achieved waveform so the requested amplitude and mean hold across a long run.

Measurement

A number is only as good as its chain.

Acquisition, transducer identity, calibration and the algorithms that turn a raw curve into a reported property — the part of the software that decides whether a result stands up.

High-rate acquisition

Sampling to 400 kHz on the fastest configuration, with peak, valley and timed capture selectable per test.

Accuracy class

Load and strain measurement verified to ±0.5% of reading, against the machine standards published on each product page.

Self-identifying sensors

Load cells and extensometers announce themselves and load their own calibration, so a channel cannot be read against the wrong scale.

Digital calibration

Calibration is held in software with absolute zeroing, and re-ranging a machine is a cartridge change rather than a rebuild.

Result algorithms

Yield, modulus, offsets, cure parameters and viscoelastic terms computed from the raw curve, not estimated from a summary.

Formula calculator

Derive your own quantity from any acquired channel when the method calls for something the library does not already carry.

Statistics

Batch statistics with outlier handling across multiple specimens, so a set is judged as a set.

Stiffness compensation

The frame and the cell deflect under load; compensation subtracts them, so what is reported is the specimen.

Reporting

The test ends at the report, not the curve.

Plot live, overlay a batch, lay the report out to your own quality document, and export it in the format the next system expects.

Real-time plotting

The curve draws as the test runs, on axes you choose, with several live windows open at once.

Overlay and compare

Multiple curves on one set of axes with offsets, which is how a batch is read rather than a single specimen.

Report layout

Report format follows the user's choice, not a fixed template, so it can match an existing quality document.

Export

Spreadsheet, PDF and raw CSV, with graph and report printing including full statistical analysis of multiple tests.

Re-analysis

Stored data can be re-opened and re-analysed after the fact without re-running the specimen.

Any unit system

Units are selectable throughout, so a report can be issued in the customer's convention rather than converted by hand.

Export of test and graph data to Excel for custom processing, report generation and customisation.p.3 (PDF 5)
Export of test graph data and sensor raw data to spreadsheet; X-axis and Y-axis data of the graph can also be exported for further analysis.p.6 (PDF 8)

Platform

Where it runs, and what stops it.

Current Windows over standard Ethernet, consoles at the bench or on a shared server, and safety enforced in software above the mechanical stops rather than instead of them.

Windows 11, 64-bit

Runs on current Windows at 1920 × 1080, with no interface card required.

Ethernet

Industry-standard Ethernet between console and machine, which is what makes remote support possible at all.

Remote access

Machines can be reached over the internet for diagnosis, so a fault is investigated before an engineer travels.

Touch console

Run a test at the bench from a soft touch panel, or from a shared server, rather than tying one PC to one machine.

Software safety limits

Load, displacement and speed limits enforced in software, above the mechanical stops rather than instead of them.

Overload protection

Electronic limits protect load cells and extensometers, and a safe overload mode governs what happens when one is reached.

Interlocks

Enclosure interlocks, emergency stop and grip-action safety, tied into the same control loop as the test.

Power management

Programmable sleep and auto power-down between runs on machines that support it.

Test speed limit — a software safety feature active in all control modes; if an extensometer slips or the specimen breaks or slips, the crosshead's maximum speed is capped by this limit so it cannot over-run, protecting machine and specimen.p.7 (PDF 9)

PC interface through RS-232 and a USB serial port; no slave card has to be fitted inside the PC.p.3 (PDF 5)
Console rear panel provides dedicated ports for Camera 1, Camera 2, Extensometer 1, Extensometer 2, Load Cell, Analog Port, PC-Port, Printer, Remote, Reset and the Drive Connector, with model number, serial number and manufacturing date on the plate.p.4 (PDF 6), console rear-panel photograph
Per-stage digital input, digital output and temperature channel columns in the stage table, so external devices and a temperature channel can be sequenced with the test.p.8 (PDF 10)
The Universal Control console is compatible with all previous Dak models and with the majority of testing machines of other makes, and keeps older frames working with current computers and operating systems.p.3 (PDF 5)
The Console stores six test procedures under names of the user's choice; the catalogue's worked example names them Rubber Dumbbell, Rubber Compression, Flexural, Plastic Tensile, Wire Tensile and Fix Load Test.p.3 (PDF 5)
Each stored procedure keeps its own test speed, gauge length, pre-loading, results to be obtained and printed, load tare options and crosshead return option, so selecting the test sets every parameter.p.3 (PDF 5)
The Console's live menu offers six procedures with edit, new-batch and enter softkeys.p.4 (PDF 6), console LCD photograph
Interactive 40 x 4 back-lit alphanumeric LCD display.p.4 (PDF 6)
The Console gives run, stop, crosshead positioning and return, entry of test parameters, and control of the pneumatic or hydraulic grips, at the load frame itself.p.3 (PDF 5)
Console keypad: special keys with menu-dependent assignments, multi-function keys with function-dependent colour coding (red for crosshead motion, blue for printing, black for numeric), crosshead motion direction indicators for low-speed work, a soft power-on switch and a flexible mounting stand.p.4 (PDF 6)
Console mains input is universal, 90 to 260 V at 50 Hz or 60 Hz.p.4 (PDF 6)
Console is built on a high-speed microcontroller and is compact and light.p.3 (PDF 5)
Programmable sleep and power-down modes save power when the system is idle; sleep switches off power-consuming devices such as the servo drive while keeping the load cell and extensometer supplies live, so there is no warm-up when a key wakes it. Power-down switches the complete system off after a defined idle period.p.6 (PDF 8)
Machine operating environment for the workstation: 10 to 38 °C, storage −40 to 66 °C, humidity 10 to 90% non-condensing, single-phase supply 100/120/220/240 VAC ±10% at 47 to 63 Hz (220 or 440 VAC 3-phase on the largest frames).p.12 (PDF 14)

Compliance

Written down, and sourced.

The standards the measurement chain is verified to, the method libraries that ship with it, and every published figure with the catalogue page it came from.

Force verification

The measurement chain is verified to the published machine standards — ISO 7500-1, ASTM E4, EN 10002-2, DIN 51221, JIS B7721.

Strain verification

Extensometry verified to ISO 9513, ASTM E83, EN 10002-4 and BS 3846.

Method libraries

ASTM, ISO, DIN and IS methods ship pre-configured, and a method you build is portable between machines.

Independent validation

Test software validated against NPL-UK reference data.

Every figure sourced

Every specification in the dossiers below carries the catalogue page it is printed on, so a claim can be checked rather than taken on trust.

By machine

The full published specification is tabbed across all 6 machine families, so you read only the one you are specifying.
