Voltmeters

Voltmeters are instruments that measure the voltage, or potential deviation, between two points in an electrical circuit. Voltmeters are panel mounted devices that can display with either an analogue or digital display. Analogue panel voltmeters have a pointer that moves along a scale proportional to the voltage level. Digital panel voltmeters measure the potential deviation in the same way and display this with a digital readout.

What are voltmeters used for?

Voltmeters can measure voltage levels in generators or fixed machinery. They're commonly used in chemical processing plants where pressure, temperature or fluid-flow readings can be converted into voltage measurements.

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 is the high voltage range capacity of 200KV.

Types of Digital Voltmeters

Digital panel voltmeters have a number of 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.
