Overview

The DEWE-3143 is configured in a “notebook computer” form factor, with a flip up 15” touchscreen that opens up to reveal a keyboard and trackball underneath. The left side panel has the signal inputs, CAN BUS interfaces, and expansion connectors. The computer connections are on the right side of the system. The system runs from its own batteries, which plug into slots that are protected behind a door on the rear panel. These batteries are hot-swappable, so you can exchange them while the system is running from them, and you can keep it running forever in that way. Or you can plug the system into AC power using the included AC/DC adapter. This adapter is powerful enough to power the system and recharge the batteries simultaneously.

You can also power the system directly from DC power, from 18-24 VDC. If you need to power the system from 9-18 VDC, as in a vehicle, we have an isolated DC/DC power supply that will allow you to run the system from 12VDC (which can vary quite a bit). This isolation also protects your signals from being influenced by the vehicle’s power system, ground loops, and more.

Inputs

The Thinhand features 8 universal input channels, which can handle just about any kind of sensor via our popular MSI adapters. Natively each of the inputs can handle full bridge strain gages and voltages up to +/-10V. There are also 8 synchronous counter/encoder “super counters” built in, which can be configured as up to 24 TTL digital inputs instead of the counters. There are 2 high speed CAN BUS interfaces, and DEWESoft-SE software is built-in and ready to go. The DEWE-3143 is 100% ready to go right out of the box! But of course you can add some popular accessories, such as our MSI adapters, or some mating cables for the counters.

Above - the conditioner and A/D subsystem of the DEWE-3143 Thinhand

• Eight great dynamic analog inputs, which natively handle full bridge sensors and low voltages
• Each of the analog inputs can be adapted to handle IEPE, charge, thermocouples and RTDs using our intelligent MSI interfaces (see below for details)
• Eight advanced counter inputs. Each one can be configured as a counter, timer, RPM converter, encoder input, and more. These inputs are 100% synchronous with the analog inputs, of course.
• 24 digital TTL input lines
• Two high-speed CAN BUS interfaces, so that you can connect up to the data busses in all kinds of cars, trucks, aircraft, trains, and more. Everything is recorded synchronously to a single data file within DEWESoft.

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.


DEWESoft can be extended to handle a wide variety of applications, including human body vibrations, as shown in the screen above. Record accelerometer data and output in real time calculations in accordance with international standards related to whole body, hand, arm etc studies. The option called DEWEsoft-OPT-HBV can be added to any Dewetron system which has high dynamic range acceleration inputs, like the DEWE-3143.

Ideal human vibration study portable package:

• DEWE-3143 data acquisition system
• 8 x MSI-BR-ACC accelerometer adapters
• DEWESoft-UP-DSA (software option includes the human vibration addon, order tracking, and more)

Options & Upgrades

Channel Expansion
The DEWE-3143 can accept one DEWE-43 (requires also the 43-SYNC option), and thus the channel count can be doubled:


What you need to add:
The DEWE-3143 does NOT require anything to be added to be a complete system. However, there are some accessories and add-ons which might be of interest:

Popular add-ons and accessories (can be added anytime):

• One of our MOB(ile) displays, perfect for in-vehicle use.
• Common carrier rated shipping case to protect the system during shipment
• DEWE-CAM-01 or other video camera add-ons
• DEWE-VGPS series GPS sensor/interface
• Isolated DC-DC power supply, so you can power the system from a wide voltage range, and protect the signal quality from interference on the vehicle’s power system
• Popular sensors such as accelerometers, mics, thermocouples, encoders, and more
• MSI interfaces (see list below). MSI-BR series are compatible with the MDAQ-SUB-BRIDGE-D and MDAQ-SUB-STG-D

Even longer battery running times...
Want to power this system for even longer without line power? Order the 24 VDC model plus one of our Neutrino-4 battery charger/supply units. The Neutrino-4 can power this system for hours at a time! You can buy additional batteries and hot swap them into the Neutrino-4 for even more running time. The Neutrino-4 comes with one battery as standard, but you can add three more, and provide tons of running time for Dewetron DC powered and battery/DC powered systems.
