Overview

Eight IEPE inputs
The DEWE-3110-DSA features 8 inputs which have built-in IEPE input signal conditioning. Or you can use any channel for voltage input up to +/-10V. When the IEPE mode is activated, each input provides the constant current excitation that is needed to power piezotronic accelerometers and microphones.

In addition, each of the eight inputs features TEDS, so when you connect any TEDS compatible sensor, it will be read and all of its settings will be added to the on-board sensor database! This is a great feature of Dewetron’s hardware and software: real TEDS compatibility. You can also manually add non-TEDS sensors into the database for “quick pick” during setup.

There are also two high-speed synchronous COUNTER/ENCODER inputs, which we call “super counters,” because each one can handle a full quadrature encoder. Or use them for simpler tach inputs. These are ideal for order tracking, as well as for the rotational and torsional vibration features inside the DEWESoft-DSA software.

Finally there are some digital inputs (TTL level - factory upgradable to higher input levels), and an EPAD connector in case you need to connect some additional low-speed voltage, thermocouple, or RTD inputs.

24-bit resolution with ANTI-ALIASING
• Core2Duo processing platform with removable 250 GB HDD
• Bright 15” touchscreen display
• Runs hours from its own batteries
• Also runs from 120/240 VAC
• Made in USA
The DEWE-3110 Thinhand-DSA has our ORION-0824-200 card built in, so therefore it has eight simultaneously sampled inputs with up to 200 kS/s/ch sample rate. Each input can be a low voltage OR an IEPE signal conditioner channel with constant current excitation built in. So it’s made for accelerometers and also low to medium voltage input channels. DEWESoft-PROF is also built-in, and you don’t need to add anything unless you want to! The system is 100% preconfigured and ready to roll as soon as you unpack it and turn it on. But of course you can add some popular accessories, such as our MSI adapters, or some mating cables for the counters.

The ORION-0824-200 A/D card at the heart of the DEWE-3110-DSA provides bullet-proof anti-aliasing filtering, protecting you against the false signals caused by sampling too low.

Inputs

The inputs of the DEWE-3110-DSA are versatile IEPE inputs which provide the constant current needed to power piezotronic accels and mics (aka ICP, or IEPE sensors). The inputs are also TEDS compatible, and will automatically read any TEDS sensors that you use connect, and add them to our sensor database. You can also manually populate the database with your non-TEDS sensors.

Software

Most data acquisition software packages allow you to display and record data from A/D cards, to control signal conditioners, and record data to RAM or disk. Of course, DEWESoft handles all that easily - but that’s just the beginning. Imagine if you could plug all these addition devices into your data acquisition system, and add them to your recordings in perfect sync:

• Video cameras - from inexpensive webcams to fast synchronizable cameras, even high speed video cameras, infra-red, and low light cameras
• GPS sensors - record your exact position, heading, speed and distance, and draw a real-time map as you move around
• CAN BUS interfaces - view and record dozens - even hundreds of parameters - directly from the CAN bus that is built into every car, truck, motorcycle, most aircraft engines, modern trains, and thousands of CAN based sensors!
• ARINC 429 aircraft data bus, from countless commercial aircraft
• MIL-STD 1553 aircraft data bus, from military aircraft of all kinds

Well, DEWESoft makes all that possible -- and more! Learn more about DEWESoft.

But the DSA version goes much farther, adding advanced capabilities for machine and human vibration, order tracking, torsional and rotational vibration, sound level meter, and much more. Here are a few highlights:

DEWESoft DSA dynamic signal analysis edition
The DSA edition is the dynamic signal analysis edition of DEWESoft, which includes all advanced capabilities of the PROF edition, PLUS adds these more advanced features and capabilities for industrial acoustic, structural analysis, and machinery diagnosis:

• Industrial acoustic: real time narrow band FFT, real time 1/1, 1/3, 1/12, 1/24 band octave spectrum

• DEWESoft-OPT-FRF - FRF/modal analysis, SISO, SIMO and MIMO configurations with H1, H2 and Hv algorithm. Excitation can be either an impulse (modal hammer) or continuous. Structure geometry can be created or imported from UNV, online measurements of FRF, coherence, phase and amplitude is possible.

ORDER TRACKING
Order tracking is a procedure to transform data, mostly from vibration, to the angle domain based on the frequency of rotation. DEWESoft order tracking takes time domain data and transforms the data based on frequency of rotation and extract any number of harmonics (amplitude and phase angles) which can be displayed in Bode, Nyquist, 3D FFT, real time x-y and orbit plot. For more info, visit Order tracking solution report.

TORSIONAL VIBRATION
This module calculates the torsion angle and angular vibration measured from two encoders mounted on each side or the shafts. The difference between the rotations of each side is the torsion twist of the measured shaft. Torsional vibration can be an input for order tracking to give clear idea about dynamic behavior of shaft. Several torsional vibration modules can be combined to measure the complicated transmissions.
