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.

Features:

​

• Battery or mains operated and easily portable

• Configuration and Metering by:

  • Panel Controls and display

  • Locally connected PC using Darca Software

  • Remotely connected PC (using Darca Software) via GSM, landline or radio modem

• Measure up to 250 analogue or digital channels, such as temperature, humidity, pressure, voltage, resistance, current or any other suitable sensor output

• Non volatile internal memory providing up to 2 million readings of secure data

• Readings can be scaled into appropriate units (e.g. m/sec, p.p.m.)

• Low power consumption for long term unattended use or portable operation

• Customised firmware for specialised requirements

• LAN Network adaptor for Ethernet connection

• Highly accurate: ±(0.1% of reading, +0.2% of range span)

• 12 bit resolution

• Sensor power outputs

• 1 pulse count channel and 8 event/digital channels in addition to other inputs

• External triggers can start and stop the logger

• Rapid memory download at 38400 baud

• Up to 99 logging "runs" may be stored

• 3 year guarantee

Squirrel Modules

Each Squirrel Datalogger typically contains one CPU module and at least one input module. The CPU module contains two inputs of its own; one event input and one pulse input. Up to 8 input modules can be combined into one Squirrel Datalogger, for a maximum total of 250 input channels.

​

Which modules are available?

​

• U Thermistor Type U

• K/T Thermocouple type K or T

• P Platinum Resistance PT100

• V/C Voltage or Current

• AC AC Voltage or Current

• pH pH

• Co Conductivity

• B Pulse Count

• F Frequency

• D Event / Digital

OPTIONAL MODULES FOR USE WITH THE CPU ONLY

(No additional height added)

Note: the CPU is provided with 1 x B input as standard
One only of the following modules can be added to the CPU.

MXP - Adds 1 additional B input (100 Hz Maximum)
MF2 - Adds 2 additional F inputs (standard 1 x B input forfeited)
MF3 - Adds 3 additional F inputs (standard 1 x B input forfeited)

Sensors

The Squirrel enables cost effective direct connection to a whole range of sensor types including temperature, humidity, and pH with options for pulse, frequency and digital inputs (Ideal for logging contact closures, shaft rotation and digital output form a weighing scale respectively).

There are also inputs available for measuring voltage and current (both AC and DC) .
