Metromatics portable DEWE-3020 measurement instrument

The portable DEWE-3020 is said to be the smallest, rugged ‘all-in-one’ measurement system for galvanically isolated amplifiers. It includes a built-in touch screen, high isolation signal inputs, high sampling rates - up to 1 MSps, up to 24-bit resolution and a data throughput of 70 MBps.

The system can be powered from AC or DC or from external power with the ‘hot-swappable’ battery power supply option.

Analog, digital, CANbus, GPS, video data and counter are already synchronised during recording.

DEWESoft enables synchronised data acquisition and analysis from different signal sources. The Core 2 Duo processor supports the high-performance online mathematical functions, displaying data on different screens during measurement.

In analyse mode, the mathematical functions can be applied to previously acquired channels and simple reports can be generated. Results are shown online on the 15.4″ TFT display with touch-screen.

The optional battery power supply (operational time - up to 3 h per battery set) turns the device into a fully battery-powered instrument. The two ‘hot-swappable’ batteries give continuous operation without an external power source.

The instrument offers 16 differential or eight isolated analog inputs - an extension to 16 isolated inputs is made possible by using an external rack. Sensors can be connected via TEDS (transducer electronic data sheet). Another way to expand the measurement functionality is to use an modular smart interface (MSI).

This is an add-on for bridge and voltage amplifier modules that enables the measurement of thermocouple, IEPE, RTD, Pt100 to Pt2000, charge or voltage up to 200 V.

The device offers up to 64 digital inputs, 16 digital outputs, 20 counter/encoder inputs, 4 CANbus interfaces, FlexRay, ARINC-429 and MIL-STD data buses.
