Voltage indicators
Voltage indicators are small installation devices for measuring both alternating and direct voltages.  Voltage indicators continuously show the current voltage. Voltage indicators are used to check batteries or mains voltage. Since power plants in the industry as well as measuring equipment in research are very important, in most cases a monitor with the help of voltage indicators is essential. Besides, many quantities are shown as voltage. Scalable voltage indicators can transform a voltage value into the corresponding measured quantity. Our voltage indicators can be used for many different applications. Apart from measuring alternating and direct voltage, some voltage indicator models allow the measurement of current and temperature. The current voltage is shown on the LED display. The PCE-N20 series voltage transducers allow to display the measured values in different colors when the limit value is exceeded. Alarm contacts also allow to take automatic measurements when the limit value is exceeded. Parametrization is performed through the program interface by means of an adapter which converts software commands to be read by voltage indicators.

It is often necessary to control voltages in the industry and laboratories. Voltage indicators are used for this purpose.  Voltage is measured in volts [V]. The Volt is the SI derived unit of the electromotive force. It is named in honor of the Italian physicist Alessandro Volta. One volt is defined as the value of the voltage between two points when a current of one ampere dissipates one watt of power. Common SI prefixes are micro [µ], mili [m], kilo [k] and mega [M]. Measuring lines are parallel connected to the measured object to detect the potential difference between two points. This difference is then displayed. Voltage indicators can be used to check the mains voltage. If mains cables are too long and have a great load, there will be a voltage drop. Voltage indicators are also used to assess the sensors output signal. In order to do this, voltage indicators should be scaled. This means that it is necessary to indicate the voltage which is equivalent to a certain value. In smaller voltage indicators, this is performed by establishing two pairs of values. Voltage indicators should calculate mean values. Larger voltage indicators can process some pair of values to assess non-lineal signals. The calculated value is then displayed.
