Voltmeters

Voltmeters are instruments that are used in electrical circuitry to measure the voltage, or potential deviation, between two points in an electrical circuit. Voltmeters are panel mounted devices that can display results in either an analogue or digital display format. Analogue voltmeters have a pointer that moves along a scale proportional to the voltage level whereas digital voltmeters measure the potential deviation in the same way and display this with a digital readout.At RS Components, we have curated a wide range of voltmeters from leading brands in the industry, including HOBUT, Lascar, Murata Power Solutions, Sifam Tinsley, RS PRO and many more. Our range includes voltmeters suitable for AC and DC, with various supply voltage and meter accuracy options available.

What are voltmeters used for?

Voltmeters are used in a wide range of applications of industries as their function of measuring voltage levels can be beneficial in many different environments, such as measuring the voltage in generators or fixed machinery. They're also commonly used in chemical processing plants where pressure, temperature or fluid-flow readings can be converted into voltage measurements.

How do I connect a voltmeter?

As a voltmeter is used to measure any potential difference is should always be connected in parallel in your circuit. This is important because objects in parallel encounter the same potential difference.

Types of Analogue Voltmeters

Moving coil voltmeters have either permanent magnets or dynamometers as measuring components with low power consumption benefits.Moving iron voltmeters can measure both AC and DC currents by producing a deflective torque. The torque-to-weight ratio is high which means increased accuracy of readings.Electrostatic voltmeters measure current flow based on attracting, repulsion or symmetry between two electrically charged plates. Their benefits are the high voltage range capacity of 200KV.

Types of Digital Voltmeters

Digital panel voltmeters have several different parameters such as supply voltage and meter accuracy. Typical mounting options include 12-pin DIPs and traditional bezel mounts.Digital screen options include a range of red, blue or green LED or LCD display units to suit your needs under different lighting conditions. Housings can be circular, square or rectangular.
