Accelerometer amplifier saves costs, improves accuracy

"Simplifying the measurement industry" is MonoDAQ CEO Dino Florjancic's description of his company's strategy, a claim backed by the launch at Sensor+Test 2018 of the MonoDAQ E-ACC accelerometer amplifier. The module increases the accuracy of acceleration and vibration measurement because it can be placed close to the sensor, so making a substantial saving on cabling.

Monodaq E-ACC is a small, compact device in a robust aluminium housing consisting of analogue front end with 18kHz alias-free bandwidth, 24-bit ADC converter with up to 40kS/s sample rate and EtherCAT interface. At its heart is an ARM Cortex processor.

The EtherCAT protocol is a key factor in enabling large distances between devices - up to 50m node-to-node. Devices are daisy-chained with a single network cable that carries signal and power.

Synchronisation below 1µs is ensured along a virtually-unlimited chain of MonoDAQ E-ACC devices.

Each MonoDAQ-E device has a fully isolated front end with high dynamic performance as well as TEDS support for sensor auto-recognition.

MonoDAQ has worked closely with DEWEsoft, the Slovenia-based data acquisition supplier and the MonoDAQ E-ACC devices come bundled with powerful DEWESoft software which enables engineers without specialist electronics knowledge to be able to measure their phenomena of interest – usually acceleration, force, pressure, temperature, etc.

Analogue, digital, GPS and video signals can be measured in the same environment and synchronised without any customisation - no programming is needed to make a high-fidelity measurement.
