Data loggers and data recorders acquire digital data from sensors and other signals. Typically the device is used in situ or in the field, and stores data over a period of time. The data is then usually downloaded and stored to a computer system for historical recordkeeping and analysis.
The term data logger is primarily used to describe a device that stores data for subsequent download to a host PC. Data recorder is a broader term used to describe any device that records sensor...

Who Took Our Poll?Top
IBA corp has been our most recent purchase, so far we have as of yet to find its parallel in data acquisition. The best feature is the free analysis tool that comes with it; we can zoom in on data all the way to the individual data points, store data both as continuous data and by product ID.
Veriteq's new loggers are great and Ellab's software is easy to use. GE's RF units are a good design idea with poor quality design.
Applications and UseTop
Because Colombia is a mountainous country, one of the factors that affect tire performance is the temperature in the flange area caused by the excessive use of brakes. We use loggers to record and evaluate tires temperature to the working conditions different routes of the trucks.
Mistakes are using data loggers with wrong temp. range which makes data incorrect. Resolution and efficiency.
More datapoints, faster scan time. Would be nice if the price were lower, each unit and license is fairly expensive, well worth it, but hard to justify to accounting. Since our last purchase they have added lots more features that we haven't yet explored, so I wouldn't classify myself as an expert on their systems, but I absolutely love the ones we have at this point in time.
Wireless or GSM transmission, Low power consumption, Power backup, Intelligent central server software for controlling a number of loggers remotely, Enable activation of circuits through relays or active electronics.
Scalable, low power consumption, TCP/IP enabled, flexible programmability. Multiple counter and analog inputs, sampling rates up to 1/30 second, SD or other removable card for memory and program files
If you have more than one system that's being monitored, be sure to get the files synchronized. Our systems run on different PC's and the PC times aren't synchronized; This can lead to some false assumptions if you don't take that into account.
Check software and the ability to integrate the hardware with homemade software, Check simultaneous data view and the ability to download while system is still logging, Check idiot proof operation, Check if external power is used, that the data logger moves to battery when power fails. Long life battery.
Full connectivity, open software for drivers and control soft. Do not be impressed by sampling frequency if you will measure mere day-to-day signals.
