DK191P Industrial Controls

Panel Meters

Panel meters are instrument used for monitoring and measuring electrical current, voltage, and other electrical parameters. They are often found in electrical cabinets and control panels, providing a sense of control and providing a quantifiable means of evaluating electrical conditions. The most common type of panel meter is the DK191P.

DK191P Application Field

The DK191P is an AC and DC voltage and current meter with a measuring range of 0 to 3600 mV AC and 0 to 600V AC, 0 to 600V DC, and 0 to 300 mA DC. It is typically used in a wide range of applications including electric control equipment, lighting control systems, alarm systems, and process panels. It is particularly useful for checking for short circuits and monitoring battery and charger circuits.

DK191P Working Principle

The DK191P meter works on the principle of postulated potential differences. This means two potentials in the system are measured in a manner that allows for an indication of the current or voltage. The meter’s two active contacts measure the potentials, and these are then translated into an electrical current or a measurable voltage. The resulting display shows direct readings in volts, millivolts, or amperes.The principle of voltage division is also used; this involves the division of the source voltage by means of a variable resistance. This reduces the source voltage to an appropriate level that can be measured with the meter. This type of operation is particularly useful in situations when the source voltage is too high to be read directly by the meter.The DK191P also includes a range selector switch which allows the user to select certain ranges of voltages and currents appropriate to the application. This type of range selection provides greater flexibility in the operation, and avoids any over-current or over-voltage situations.

Conclusion

The DK191P Panel Meter is a well-designed and feature-packed instrument for measuring voltage, current, and other electrical parameters. Its postulated potential differences working principle provides a convenient and accurate way to read electrical values, while its variable resistance system allows for effective range selection levels. The DK191P is a must-have device in any electric control panel.
