Custom Data Loggers

Eltek is specialised in custom made portable data logging systems to satisfy a wide range of user requirements. Our datalogging systems can be divided into two categories:

  • Wired Loggers, which allow the user to directly connect a number of sensors to the datalogger itself
  • GenII Telemetry systems, which consist of a number of wireless 'transmitters' which report data from their connected sensors to a central logger/receiver via radio.

A range of software packages is available for downloading, maintaining and analysing the data from our data logging systems.


1000 Series Squirrel
Low Power Multichannel Customizable Data Logger

Eltek 1000 Series Squirrel data loggers provide a flexible combination of channels, ranges, memory sizes and extra options. If there is not already a model which fits a particular application, then Eltek can almost certainly make one.

Modular design

The basic element of the Squirrel data logger consists of the main board and the battery pack. The main board contains the power connector, display, RS232 serial connection, a pulse input, an 8 bit digital signal input and output connector. Up to eight additional input modules are connected to the main board during manufacture depending on the sensor input requirements.
