PCE Deutschland voltage data logger PCE-VR 10

The Voltage Data Logger from PCE Instruments is used to record up to three input channels of 0 ... 3000 mV signals via three input channels. The voltage data logger stores the measured voltages on an SD card in Excel format. To record also higher voltages in the range between 0 ... 10 V a voltage divider can be used. The measured voltages are transmitted via plug-in terminals to the data logger, which displays the corresponding values directly on the display and simultaneously stores them on the memory with the associated time stamp. A scaling of the measuring signal is not necessary, because the measuring values are stored directly as mV-measuring value. Scaling can then be conveniently performed manually in Excel.

The voltage data logger thus determines the pure raw data of the sensors whereby any further processing and data evaluation can be carried out very flexibly via spreadsheet programs such as Excel. In addition to storing the measured values, the voltage data logger displays the values of the respective voltage channels on the large backlit LC display. The maximum resolution is 0.1 mV with an accuracy of 0.5 % + 2 mV. The voltage data logger is operated with 6 AA 1.5 V batteries or a power supply unit. For visualization of the live measured values the data logger from PCE Instruments can be connected to the PC via the serial interface. The storage intervals are adjustable in several steps between 1 second and 600 seconds. Thanks to the robust housing, the voltage data logger can be placed on a table or mounted on a wall. This allows mobile measurements at different locations as well as stationary measurements, e.g. if permanent recordings are to be made at only one plant.

Areas of application for the data logger for voltage If measured values and data have to be recorded, compared and later documented over longer periods of time, data loggers which are usually specially designed for the corresponding variables are suitable in most cases. Often it concerns variables such as temperature, humidity, pressure, energy, light, pollutants or current and voltage. Data loggers consist of a storage medium such as an SD card, an interface (USB, Bluetooth, WLAN...) and at least one channel for the corresponding measured variable. Often there is also the possibility to record different measured variables simultaneously via several channels. The voltage data logger from PCE Instruments is specially designed for the field of electrical voltage measurement and is therefore suitable for parallel recording of voltages on a maximum of three voltage channels.

The voltage data logger is used to record e.g. sensor data which can be read out via a voltage output. The measuring range of up to 3000 mV can be extended for sensors with higher voltages up to 10 V via a voltage divider (see optional accessories). If, for example, physical variables such as temperature, pressure and level are to be recorded and compared simultaneously in a system, the corresponding sensors can be connected to the data logger in order to display and document the changes and mutual dependencies of the three variables after the measurement. The voltage data logger can also be used to compare identical sensors at a measuring point. In this way, sensor errors can be directly excluded before permanent installation and measurement. Air pressures before and after filters can also be checked with suitable sensors in order to test the filter function. The data loggers for voltage are therefore suitable for a wide range of applications in industry, maintenance and repair or research and development.
