Panel Meters - Counters, Hour Meters

The H7ET-NFV1 series is an advanced panel meter that can measure the frequency and voltage of electrical signals. It can be used to monitor industrial machinery, ensuring that motors, pumps, and other devices are operating efficiently. With its durable design and user-friendly LCD display, it is a reliable device for monitoring in industrial applications.

Application Field

The H7ET-NFV1 can be used in many industries, including food processing, mining, manufacturing, and power plants. It is especially useful in demanding environments such as oil rigs, because it can measure frequency up to 600 Hz and voltage up to 600VAC. It can also be used in wastewater and water treatment facilities, as it is capable of measuring different parameters related to the water purity.

Working Principle

The H7ET-NFV1 uses a technique known as phase comparison to measure the voltage and frequency of an electrical signal. The device splits the signal into two lines, one for voltage and one for frequency. The frequency line is then compared to the voltage line in order to accurately measure the signal. The device then compares the signal to a built-in reference signal, which can be adjusted to match the desired frequency and voltage.

The H7ET-NFV1 can be used in many different applications due to its high accuracy and signal stability. It can also be used to detect over-voltage and under-voltage conditions in order to prevent costly equipment damage. The device is easy to install, with minimal wiring, and can be used with both analog and digital displays.

Conclusion

The H7ET-NFV1 is a reliable and durable panel meter that can measure voltage and frequency up to 600VAC and 600 Hz. It is designed for use in demanding environments, such as oil rigs and water treatment facilities, and can also be used for monitoring industrial machinery. With its user-friendly LCD display and accurate signal measurements, it is an ideal choice for monitoring in industrial applications.
