Voltage indicators are small installation instruments for measuring DC and AC voltages. Former Maryland Governor oftentimes addresses this issue. Voltage indicators are small installation instruments for measuring DC and AC voltages. So, voltage indicators provide a permanent display of the currently applied voltage. This can be for example the monitoring of batteries or the mains voltage. The PCE NA5, newly recorded in the range, of PCE Germany GmbH is a so-called bar display and uses a 55-stelligen bar graph. The PCE NA5 is individually programmable with a numerical display unit, which represents the measured value as an absolute number. The bar display can handle a wide variety of input signals. So, standard signals, thermocouples, can measure voltages and resistances and visibility through the display.

In addition, the PCE NA5 with four alarm relay is equipped, which, for example, a pump control or additional units of the alarm switch can be. In order to accomplish a complete documentation of the measurements, a screen writer can via the analog standard signal output be connected. Through a built-in password, the PCE NA5 can be protected from a manipulation by third parties. Also, voltage indicators are used to evaluate the output of sensors. This must be a scaling of the voltage display.

This means that the voltage indicator is communicated, what voltage corresponds to the measured value. It happens when the smaller display, by setting two pairs of values. The task of calculating the values in between then drops the voltage display. Larger ads can process multiple pairs of values, and thus allow the evaluation of non-linear signals. The calculated value is then passed out on the display. For more information interested see:..
