Using A Voltage Data Logger

In the course of data logging and recording implemented in different environments

, voltage data loggers are in frequent use. These voltage logging devices are used for voltage (AC and DC) measurements. They are employed to measure and record voltage values over periods of time, and in addition to basic data loggers which can perform simple measurements, there are also voltage data logging devices that feature analysis functions as well as integrated displays.

For simple voltage measurements and recording, simple voltage data loggers can be used; they acquire data directly to a PC, and they have built in USB interface. Some simple data loggers for measuring voltage values can automatically calculate the dew point. They are easy to use and are inexpensive to purchase.

As mentioned above, voltage data loggers are data loggers which can measure DC or AC voltage. There are simple models specifically designed for voltage measurements, but they do not have great flexibility, although their cost is lower. That is why general purpose data loggers are to be preferred when flexibility is important in the specific environment, as they can be used to measure a number of input signals types.

There can also be environments and needs to monitor a mix of DC and AC voltage inputs. Then the solutions are universal input voltage data loggers which can measure a range of input types, and that can be achieved by means of outfitting them with transducers.

Multichannel voltage data loggers can acquire the voltage data directly to a PC, or to a removable SD memory card. They also have built in USB or Ethernet interface. They have a number of selectable gain ranges per channel.

High voltage data loggers for AC/DC voltage measurement feature built in memory for data recording. They typically have USB 2.0 communication interface. They can also comprise an alarm function. High voltage data loggers can be used in a wide range of applications, such as rail voltage monitoring, power supply monitoring, windmill monitoring, battery testing, intermittent detection of voltage faults, etc.

In addition, there are data loggers which offer the versatility of measuring a number of values, such as current, resistance and temperature in addition to voltage. They feature large and clear graphic LCD screens to enable easy access to readings, and they also offer a host of advanced functions, for example mathematical channels or high speed logging. They can handle analog, digital as well as other types of variables with a high resolution and high speed.

When choosing voltage data logging devices, it is important to take into consideration the specifics of the environment in which measurements are to be performed. The choice of interfacing type is also important, and when there is no need to use voltage data logging devices as stand alone ones, loggers that interface with a PC and use software to activate the logger can be used.
