HGL Dynamics Data Acquisiiton Overview

HGL Dynamics has developed Data Acquisition Modules (Front-Ends) which allow capture of signals from DC into the Megahertz range. Within rotating machinery applications this broad spectrum is usually divided into three bandwidth areas of interest, namely:

Steady-State

HGL’s Data Acquisition products fit together to cover the entire 1Hz to 10MHz range with hardware that is always rugged, always uses one ADC per channel and provide tight synchronisation across the entire system regardless of which units are used.

HGL’s software fully supports all the hardware variants and provides a simple way to quickly and efficiently configure and control systems from 4 to 1000+ channels from a single Graphical User Interface (GUI).

The Chart below shows which of HGL’s product families fit within the different sample rate sectors.

Common Features

Modular

All HGL Dynamics Data Acquisition Front Ends are modular and can be used with any other Front End across the Sample Rate ranges.

Units are available in channel counts from 8 to 48 (see detailed product pages)

Rugged

All products are designed to be environmentally robust for exposed operation in all weather conditions and temperatures for extended periods.

Most units are shock and vibration tested to DO160G standards to levels appropriate with their inteded use (up to Category R Curve W)

Built to last

HGL designs and manufactures all of its products for 10+ year life, using milled anodized Aluminium for Chassis and internal construction with high quality multilayer PCBs and surface mounted components.

Power

Every HGL Dynamics Front End can be powered by DC 9-36V (automotive standard) and AC through an mains adapter.

Additionally most units have either Power over Ethernet (PoE) or USB where applicable.

Communication

HGL standardised on Ethernet as its system ‘bus’ in 2001 and since that time every HGL Front End has featured Ethernet using TCP/IP and UDP protocols.

More recently we have added USB communication to some of our portable products.

Synchronisation

Every HGL Front End features single ADC per channel with synchronisation to nanoseconds across small, medium and large systems regardless of module type.

Every module includes HGL’s own LVDS system with IRIG A/B, GPS and IEEE-1588 available depending on module types. (See detailed product information).
