A voltmeter is a device used in electrical circuits to measure the voltage or difference in electrical potential between two points. These devices can measure both direct and alternating current, with readings typically displayed in volts, millivolts, or kilovolts. Modern digital voltmeters offer a precise and easy-to-read display, making them a popular choice for accurate voltage measurements. In this blog, we’ll explore the various functions of a voltmeter and how both analogue and digital voltmeters are used in different applications.

GTS offers arange of voltmeters with various supply voltage options. Our selection includes instruments ranging from 8V to 32V, with our 12V voltmeters being especially popular. A variety of supply voltages and meter accuracy options are available in GTS's voltmeter range. We sell instruments in 8V-32V ranges in addition to our popular 12V Voltmeters.

Voltmeter Applications

Voltmeters are employed in a broad variety of industrial applications due to their ability to measure voltage levels in a variety of settings, such as tracking the voltage in stationary machinery or generators. Additionally, they are frequently employed in chemical processing facilities where readings of pressure, temperature, or fluid flow may be translated into measures of voltage.

Connecting a Voltmeter

A voltmeter should always be wired in parallel to your circuit since it is used to measure any potential difference. Because objects in a parallel meet the same potential difference, this allows for an accurate reading.

Analogue Voltmeters

Analogue voltmeters offer low power consumption advantages by using either dynamometers or permanent magnets as measurement elements. Because of the high torque-to-weight ratio, measurements are more accurate. Using the attraction, repulsion, or symmetry between two electrically charged plates, electrostatic voltmeters gauge the flow of current. Their advantages include a 200KV high voltage range capacity. 

At GTS we sell 52mm Voltmeters that measure either 8-16V ranges or 16-32V. We also offer Marine specialised 52mm Voltmeters that measure the same ranges.
