High Resolution Measurements

The NDACS 6000 utilises a low noise 24 bit ADC for all of its analogue acquisition operations. Combined with its low noise sensor pre-amplifiers input noises below 1 uV are achieved. The low electrical noise ensures that applications such as structural monitoring using load cells, temperature monitoring with thermocouples and RTDs can be accurately carried out. The instruments provides results only expected with systems consisting of many times this units cost.

Status Messages

A series of status messages can be sent at preset time intervals or when the instrument restarts to indicate that the system is alive and functioning correctly. These messages are useful to show that the instruments are working when deployed remotely or when waiting for a specific in frequent event to occur.

Web Interface

The NDACS 6000 contains an embedded Web interface enabling the configuration of all instrument operations to be carried out using a standard Web Browser no matter which communication interface is being used. The User Interface is the same no matter if the connection to a system is made via the Internet or dial-up telephone connection. Any computer using a modern operating system will be able to examine data without the need for any third party applications software.

Flexibility

The NDACS 6000 is one of the most flexible low cost instruments upon the market today. Not only can it read and send data across a network or Internet but it can also record data internally and send automatic reports by email to a user. The instrument is fully integrated to the Internet. Not only can the NDACS 6000 be directly connected to an Internet server but is can be deployed remotely by direct connection to a modem or mobile phone supporting a data link operations.

Remote Deployment

The NDACS 6000 can be deployed remotely to acquire data continually or configured to look for a pre-determined event and to notify the user when it occurs. The NDACS contains all the software to connect directly to radio modems, standard fixed line modems, data link mobile phones and configured to send data to via most dial-up Internet Service provider accounts

Data Logging Operations

The NDACS 6000 supports 2 independent data loggers each capable of recording 13000 sample readings per channel. The General purpose recorder can be set to report data after a preset number of records and the Flash memory logger to report data when a specific event has been observed. Each of the loggers can send data to a specified User. The data files appear as attachments to an E-mail and can opened directly into Microsoft Excel or any other specified spread sheet.

Internet Connectivity

The NDACS 6000 supports all the network operations required to transmit data across the Internet via a data server. A multiple level password system ensures that data and instrument configurations stay safe when operating on an insecure network. The instrument can be configured to transmit Ethernet packets across private networks using the Ethernet configuration commands.

Compliance to European Union Directives

This product is approved for installation within the European Union and EEA regions. It has been designed and tested to meet the following directives:

EMC Directive

The analog modules are tested to meet Council Directive 89/336/EEC Electromagnetic Compatibility (EMC) and the following standards, in whole or in part, documented in a technical construction file

EN 50081-2

EMC – Generic Emission Standard, Part 2 - Industrial Environment

EN 50082-2

EMC – Generic Immunity Standard, Part 2 - Industrial Environment This product is intended for use in an industrial environment.

Operations

The image above shows a 4 instrument remote network panel system that can be deployed remotely to record and report data from any sensor connected to the system. The information can be accessed remotely by data server computer, observed in real-time by a Web Browser connected to the instruments by the dial-up modem and/or simultaneously by by a local PC connected to the Ethernet port. The instruments can be Configured to operate directly onto the Internet so as long as a suitable connection can be made information can be processed in real-time by many third party SCADA packages.

Applications

The NDACS instruments are high precision general purpose loggers and Ethernet data acquisition systems and are ideally suited to form large remote data acquisition systems. The instruments can be deployed to record data continually, to look for and report a specific event or to simply send data to remote SCADA systems across the Internet. An email alarm system can be configured to send alarm messages to multiple users should any preset condition be exceeded. No matter how communication to the instrument is made the same User Interface is maintained and all instrument operations can be configured by an industry standard Web Browser.
