CHESTERLAND OH—October 18th, 2011
CAS DataLoggers recently provided a major automobile manufacturer with the data logging solution for its rigorous performance validation testing. As part of the testing of any new vehicle, sample units were typically subject to a variety of endurance and durability tests to identify any potential weak points or failure modes and chart their performance. To gather the most detailed record of a car’s data throughout these speed validation tests and ensure the safety and robustness of the entire product line, engineers needed highly accurate, reliable data logging equipment. These devices would have to be capable of measuring the many parameters used to gauge the cars’ performance as well as be portable and compact for quick placement and retrieval from hundreds of test cars.
Plant management installed 20 Grant Squirrel SQ2040 Portable Universal Input Data Loggers in an equal number of their test cars. Subsequently, test engineers put their development cars through testing on the track at high speeds as part of their endurance testing program, equipped with temperature and pressure sensors feeding data into the SQ2040 dataloggers. The loggers were set to record the data at preset regular intervals throughout the tests, including road conditions, engine temperature and pressure data, all recorded into each Squirrel’s memory. This data gave engineers vital information on performance concerning a whole host of vehicle components.
The Grant SQ2040 dataloggers each featured up to 32 universal analog inputs for voltage, current or resistance and up to 8 inputs for digital pulse and event, supporting a wide range of analog inputs including thermistors, thermocouples, RTD temperature sensors, voltage, current, and resistance. Twin processors and multiple 24-bit ADC converters enabled precision measurements with a high basic accuracy of 0.05%, while 4 alarm outputs provided early warning capabilities whenever key parameters went out of specification.
Compact and lightweight, the high-performance Squirrel dataloggers were easy to transport to and from the test cars and intuitively convenient to use. Functioning as portable, standalone data loggers or as PC-linked data acquisition systems, the Squirrels could be battery-operated or mains powered, and were quickly configured via integral interface or by PC. Each logger offered 16 MB of internal memory for approximately 14 million readings, as well as removable Multi Media (MMC) or SD card memory. Fully equipped with the same advanced features as the Squirrel 2020 series but adding additional high speed data logging on up to four channels and twice as many universal input channels, the SQ2040 loggers had the versatility to handle the demanding multi-channel testing of the plant’s vehicles at top speeds.
The data loggers’ communications features included built-in Ethernet networking along with USB and RS232 connectivity. When a validation test was over, engineers easily and quickly downloaded the Windows-based data from each Squirrel in graphic form onto a PC for analysis. This data was then applied to existing production methodologies and resulted in safer automobiles.
The automobile manufacturer benefited in several key ways following installation of the Grant Squirrel SQ2040 dataloggers in their quality assurance program. Most importantly, the loggers could measure the wide variety of parameters needed in the tests. These data loggers featured many universal channels recording at high accuracy and offered several communications options, all at a low price. The portable Squirrels were also ideal for quick installation in the test cars and were quickly configurable which gave the project a head start.
A quality performance engineer commented: “We chose the Squirrels because they’re about the size of a small notebook but extremely sophisticated and very easy to use. Downloading the information from the loggers to our PCs enables us to analyze the data quickly and clearly. We’ve already tested hundreds of cars and the Squirrels have proven to be invaluable tools for improving the reliability of our vehicles. With these devices, you don’t need to be a computer scientist to collect, download and analyze your data.”

Grant SQ2010 Portable Universal Input Data Logger
CHESTERLAND OH—August 8, 2011
CAS DataLoggers recently provided a data logging solution for Stanford University’s Department of Pediatrics, Neonatology Division, initiating a research project to acquire data on infant skin temperatures for continuous patient monitoring. Surface temperature sensors connected to portable data loggers were recognized as the most effective means for measuring and recording all of the minute changes in temperature. These changes occurred over both short and very long time periods at locations on the body which were often difficult to measure. A normal body temperature for a healthy baby was considered as being between 97° and 100.4° Fahrenheit (36° to 38° degrees Celsius). Anything above this range could indicate a fever, serious infection, or disease, so the researchers needed extremely accurate skin temperature sensors. After looking as several different options, thermistors, which provide a larger change in output signal for a given temperature change than other sensor types, were the mandated choice for the project. Temperature readings would need to be constantly monitored on a portable, compact device capable of being programmed with customizable alarm thresholds and offering convenient data management…all while staying within the departmental budget.
The university’s Neonatology Division installed a Grant SQ2010 Portable Universal Input Data Logger within an incubator, connected to 4 Measurement Specialties Model 427 Medical Reusable Skin Surface Probes for Infants from Fisher Scientific. The data logger coupled with these thermistor probes provided 0.1° C temperature resolution for extreme accuracy along with a fast response time. The FDA-approved probes had highly sensitive, Teflon insulated pressed disk ceramic sensors for measurement of temperature and featured standard ¼” phone output connectors for easy installation. Stanford provided the probes to CAS beforehand for assembly with CAS custom-designed adapters to connect to the Squirrel data logger for a turn-key set-up.
The Squirrel data logger needed to be configured to read the probes, and CAS provided Stanford staff with technical support to get the system set-up. Using the SquirrelView software included with the kit, users configured the measurement channels and established alarm limits through the Setup window. A wide variety of sensor types were supported, and in this case, the type Y thermistor provided very accurate scaling for the Measurement Specialties sensor being used. After installation and configuration were complete, the biosafe surface temperature sensors were attached to an infant’s skin with the aid of medical tape for a maximum of 36 hours. The thermistors located in the sensors provide a resistance output that was proportional to the sensor temperature being measured by the data logger and converted to skin temperature, displayed in real-time on the data logger’s LCD screen and recorded in the internal memory of the logger for future analysis. With the appropriate equipment, the university would be able to perform the yearly recalibration themselves, or use a local calibration company.
The skin temperature probes worked very well with the Grant data logger, its portability being an asset in the limited space of the research lab. The Squirrel 2010 served as a flexible handheld data logger with up to 8 analog input channels capable of measuring current, voltage, and resistance in addition to temperature with 0.1% accuracy. In addition 8 digital channels along with 2 alarm/relay outputs provided the necessary alarm features for the project. The SQ2010 is capable of storing up to 1.8 million readings in onboard memory and features USB connectivity to a PC as well as optional Ethernet or RS232 connections.
The data logger kit also included SquirrelView Plus software designed with a user-friendly, Windows Explorer style interface allowing quick setup of the data logger, quick data downloads and direct export to Excel in real-time or as a .CSV file for customizable data analysis. Flexible data presentation allowed users to get a statistical summary of the data and then quickly display and analyze real time or historical data as a line graph, bar chart or analog gauge. Data could be downloaded by date, time or events, saving time when searching for readings from a specific period. A simple communication wizard enabled hassle-free working with Ethernet, modems, or cellular devices. SquirrelView Plus also added powerful features including graphical data analyses and advanced reporting options. Alarm capabilities included graphical alarm and event identification to set high and low alarm thresholds, letting researchers easily identify occurrences around specific events. Settings could be saved to PC for efficient reuse. Additionally, custom report template creation and customizable report facilities allowed staff to print convenient graphs and readings.
Stanford University benefitted immediately from installing the Grant SQ2010 data logger in the Pediatric Division’s medical research facility, which monitored and recorded all the data from the highly-accurate skin temperature probes. One compact data logger collected and presented all the data in organized, convenient format, as well as offering the mandatory alarm capabilities for the scientists to conduct their research using infants. SquirrelView Plus software was included free and provided an easy-to-use interface along with analysis and customized reporting capabilities. Additionally, the Squirrel data logger’s affordability made it ideal for the department budget while installing easily into the small research room. Check out the SQ2010’s product page here.
