Squirrel 2040 series, the new generation data logger from Grant Instruments, combines higher channel count with the same high performance, comprehensive features and universal inputs of the smaller 2020 in a neat compact and portable instrument.
Using multiple analog to digital convertors, twin processors and removable memory options positions the 2040 series as the ideal data logger for industrial, scientific research and quality assurance applications. The 2040 provides standalone data acquisition and metering that together with a suite of comprehensive software and functional design make the 2040 the "all in one box" first choice.
Key Features
●32 universal analog inputs for voltage, current or resistance
measurements plus 2 high voltage, 4 pulse and 8 digital event/state inputs
●Analog inputs can be used with thermistor, thermocouple and
RTD temperature sensors and 4-20mA instruments
●User selectable logging rates of up to 100Hz on a single channel
●16Mb of internal memory for approximately 1 to 2 million readings
Download of internal data to removable MMC (Multi Media Card) memory
●Easy to use removable connector
●Comprehensive access to information using the 2 line, 40
●character LCD and button panel
●Readings can be scaled and viewed in realtime on a PC or on the local LCD
●Calculated channels derived from real channels using basic math's functions e.g. channel 1 x channel 2
●USB and RS232 communication
●Non volatile flash memory - data retention is virtually indefinit
●Multiple 24 bit analog to digital convertors (ADC) for precision measurements
●Portable, battery operated or mains
Communications:
USB and RS232 serial ports are standard with external options for Ethernet, Landline and GSM
communications enabling global access and system integration of the 2040.
Multiple setups stored in internal and external memory:
A setup is the instruction that tells the 2040 how it will operate. Up to six preconfigured setups, together with the setup in current use, are held in the internal memory. In addition a further 25 setups can be loaded from the external memory. Switching between setups is extremely easy and fast using the convenient LCD display and button panel, avoiding the need to connect to a PC, thereby reducing time and effort to switch between different data logging applications.
Comprehensive configuration:
SquirrelView configuration, download and data export software permits full control and use of the 2040 data logger. The convenient LCD display and button panel enable metering and logging in true portable operation.
Concurrent sampling:
2040 multiple ADCs allows true concurrent sampling and logging. For instance one channel can
sample at a rate of 100Hz whilst retaining different sample speeds on other channels, making the 2040 ideal for measuring parameters that change at different rates such as temperature and pressure.
