Test Chambers

Recreating environmental conditions

in the laboratory is the only way to

test components properly before they

enter the real world. But most of the

environmental chamber systems are

not flexible in size. The ET and EM

series showcased by the Bangalore-

based Envisys Technologies provide

flexible choices and the very latest

technologies for environmental testing

including custom sizes and custom

features.

The ET series is capable of addressing

varied volumes to suit product/

component-level environmental testing

applications for temperatures ranging

from -70 degrees C to 180 degrees C

and 10 percent to 95 percent relative

humidity. The EM series is suitable to

test smaller products such as electronic

and automotive components, as these

chambers have a compact design that

allows them to be easily mounted on a

bench or table-top. The company also

has a range of salt spray chambers for

corrosion resistance testing.

Getting things up and down to

temperature is a perennial problem for

those using environmental chambers.

To provide support, the

Hyderabad-based Weiss

Technik India presented its

new Clime Event and Heat

Event environmental chambers

that can reduce heating and

cooling rates, saving test time.

By reinjecting the refrigerant

before supercooling and

assembling the liquid line with

the suction line, Clime Event

heats up and cools down more

quickly. It is also more energy

efficient than most of the

systems in the range.

Power Amplifiers

Ensuring that electrical tests are

conducted to industry standards,

such as ISO 16750, LV124, LV148

and ISO 7637, is critical for engineers

testing automotive components. These

issues are addressed by SIB 100-TS

series linear precision four-quadrant

power amplifiers, manufactured by

SIBO Electronic Vertriebs GmbH.

The equipment is suitable for fast

voltage and current signals. All curves

relevant for those standards are

stored within the integrated curve

library. With extremely high bandwidth

at the highest power requirements

necessary for fast signals, the modular

design allows systems up to 18kW.

Furthermore, the company’s easy-

to-use WaveMaster software allows

for the generation of waveforms by a

graphical user interface or via tabular

input without the user requiring any

knowledge of software development.

Crash Test

Capturing the action from various

angles and heights is crucial for crash

testing. Besides, it often requires

connecting multiple high-speed

cameras. To address this issue, the

New Jersey-based Vision Research

has introduced the Miro Junction Box

2.0 to make this connection process

easier than ever. The original Miro

Junction Box (JBox) connected up to

six Phantom Miro cameras, but JBox

2.0 can connect six Miros, or up to four

VEO cameras, or a combination of the

two. Along with JBox 2.0, the company

exhibited its sturdy VEO 710 camera,

which offers a frame rate of 7,000fps

at a maximum 1Mpx resolution, and

the tiny Miro N-series, the capability of

which has been expanded to enable it

to operate independently, without JBox.

Road Simulator

For the requirements of passenger car

and truck test applications, including

durability, NVH, buzz, squeak and

rattle, and inline production quality,

MTS has offered a new line of

durability-capable Model 320 ePost

tyre-coupled road simulators. The

specialty of the equipment is that it

expands the application scope of

the electrically actuated segment of

its Model 320 system (four-poster)

portfolio. The new ePost systems

employ proprietary, MTS-designed

linear electric actuators. Optimised for

rigorous durability drive files, these

high-performance actuators feature

lightweight armatures with liquid

cooling and an advanced bearing

system to maximise actuator life.

Portable DAQ Device

Celebrating 22 years in the field of

testing, the Michigan-based Vibration

Research introduced ObserVR1000,

a fully autonomous data acquisition

device that is specially designed

and engineered to provide reliable

performance, accurate testing and user

friendliness. It can be simply connected

to a smartphone, laptop or PC to set

up the ObserVR1000. Once set up,

data is collected with a simple press of

the record button. The ObserVR1000

comes in four or 16-channel packages

that include GPS, microphone,

tachometer, high sampling rate, TEDS

and wi-fi capabilities, among many

other options.
