Size / performance ration has been redefined. The DEWE-101 offers eight channels with blazing 200 kS/s/ch sampling and 24-bit resolution, extremely versatile analog inputs, synchronous digital and CAN bus inputs - and more.
The DEWE-101 is smaller and lighter than you could ever imagine. That's why we call it the "Minitaur" after the mythical beast - but miniaturized. Carbon fiber and CNC aluminum construction, incredible electronics, and the best data acquisition software in the world: DS-7.

- Eight 24-bit inputs with 200 kS/s/ch max SR
- Eight synchronous counters for tach/encoder inputs
- Two synchronous high-speed CAN BUS interfaces
- Built-in computer and solid state HDD
- Easy to add a display and keyboard to complete the system
- Includes DS-7 data acquisition and analysis software
Despite its small size and weight, inside the DEWE-43 beats the heart of a giant. It's got eight dynamic analog inputs, each one backed up with a 24-bit AD converter for simultaneous sampling at the highest resolution. And the inputs are our "universal" type, which can handle strain gages and voltages up to +/-10V natively ... or connect our tiny MSI adapters and convert any of them to a different input type, including IEPE accelerometer inputs, 200V inputs, RTD's and thermocouples.
Top Applications
Locking USB connector
Our unique screw on USB connector, ensures that accidental disconnection simply cannot happen.
Isolated CAN BUS interfaces
Two CAN bus interfaces are built in, and starting with the -A models, they are electrically isolated for use in noisy environments.
Synchronizable
You can synchronize multiple systems together - requires only SYNC cables, and a software selection!
Synchronous counter/encoder inputs
Each of the 8 analog channels includes a separate advanced counter input. Or you can use each counter as 3 x TTL digital inputs.
200 kS/s/ch sample rate
Each channel has its own 24-bit A/D converter. You can set the sample rate to 200 kS/s/ch maximum, or as low as 1 kS/s/ch.
DS-7 software included
The best data acq software in the world is included with each system. Install onto your Win7 (or XP) computer and get to work!
