NetPod 4003 Introduction and features

NetPod 4003 System

Introduction

The NetPod 4003 is a new member of the Keynes Controls NetPod series of instruments have been designed from the outset to offer everything needed in a stand-alone instrument for both local and distributed measurement solutions.

The 4003 high levels of data synchronisation both between channels within an instrument and instruments across a network. The sensors inputs are securely located and offer digital filtering and high level transient/lightening protection to safeguard the instrument in the harshest of applications.

Sensor Connection

Each of the sensor inputs uses a CNT bayonet fitting self aligning plug and socket to attach signal inputs to the instrument. A physical release catch needs to be operated to remove the sensor input from the device and so makes sure that the cabling remains reliably attached no matter the industrial environment in to which the instrument is deployed.

Software Support

The NetPod 4003 is supported by drivers for most modern data acquisition and SCADA software such as:

National Instruments Labview

DasyLab

Diadem....

SCADA ... Spreadsheets

Full Software developers kit is available for the Microsoft Windows and Linux Operating Systems. Interface to any 3rd party package supporting DLL calls with only a few simple commands.

Data Synchronisation

The NetPod 4000 series instruments supports network synchronised data acquisition operations in that all channels, for all instruments on a network can be synchronised together. The synchronisation ensures that all of the individual analogue converters for each input channel for all instruments set at the same sample rate operate together to make there readings at the same instance in time.

Digital Anti-ailias Filters

All of the analogue input channels utilise digital anti-ailias filters to prevent out of band signals from corrupting the readings. These filters are sample rate following and have identical characteristics no matter what ever the temperature changes around the instrument, age of the systems and between instruments making it possible to compare signals between individual channels as well as between separate instruments on a network. As the filters are all identical no difference phase delay between inputs no matter the sensor input type will be observed and mis-interpreted as a delay in the original sensor signal.
