High Resolution Measurements

The NDACS 6016 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.

 

Remote Deployment

The NDACS 6016 can be deployed remotely to acquire data continually or configured to look for a pre-determined event and to notify a 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

 

Web Interface

The NDACS 6016 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 6016 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 e-mail to a user. The instrument is fully integrated to the Internet. Not only can the NDACS 6016 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.

Autoreport e-mail

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.

IsAlive Message: reports by E-mail at a preset date/time that the unit is operational. Ideal to show an instrument is operational when waiting a predetermined event to occur.
Boot-up Message:reports by E-mail as soon as an instrument powers on. Useful to indicate power failure at a remote site.

 

Data Logging Operations

The NDACS 6016 supports 2 independent data loggers each capable of recording 6500 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 6016 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.

Operations

The images below show two typical network layouts possible with the NDACS 6016. When operating on a LAN the instrument can be used to transmit data live to multiple users running third party applications or simply to be shown on the systems own web page data display. For remote applications data logger computer can extract the recorded data directly or have the instruments E-mail the results at preset times or upon user defined conditions.

Most modern operating systems such the Microsoft Windows or UNIX platforms contain standard utilities that .

Applications

The NDACS 6016 is a general purpose device and such can be configured to monitor a wide range of applications both in real time across a LAN or to act as a data logger. It is possible to mix sensor inputs such that a single instrument can undertake thermometry at the same time as it structural analysis tasks and to report the results automatically. No expensive applications software is required to run the instruments as they can be fully configured and data examined using a standard web browser. With the instruments low noise input amplifiers it can cope very well with signals containing a large dynamic range. It is possible using the standard features of the Microsoft Windows operating systems to schedule the automatic downloading of data.

For complex large scale applications a fully integrated SCADA system is available allowing historical as well as live data to be seemlessly viewed and archived no matter how a data connection to an instrument is made.

A software developers kit is available to enable integration of the instrument control and data analysis within most third party applications or to create stand-alone programs. The SDK demonstrates how to send data directly into applications such as spread sheets and data analysis programs.

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.



can be configured to automate the downloading of data 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.

Automatic Reporting

The NDACS 6016 has 2 independent loggers that can be individually programmed to report data at a specified time and/or after a set number of records has been recorded. It is possible to have 1 logger report data at a regular interval and the 2nd logger to wait for a specific event to occur and then report the event. The automatic reporting can be undertaken no matter what type of data link is made to the instrument.

Supported network controls:

IP Address
Subnet Mask
Gateway
SMTP IP Address

Data Display

Figure 6 below shows a typical real-time web page display available with the NDACS 6016. The analogue channel information, current CJC temperature and current time displayed in 24 hour clock notation is clearly visible. The same data display is presented to a user no matter how the data link is made to the instrument.
