99778714

Panel meters are essential instruments used in almost every industrial process and are widely used to monitor and measure various parameters. The 99778714 is an example of a panel meter that is designed to count, measure, and display hour accumulations. The meter can also be used to count external pulses such as motor starts or contact closures.

Application Field

The 99778714 panel meter is designed for use in challenging industrial environments. It features a NEMA-12/4X enclosure which provides protection from dust, viruses, and liquids. The meter’s IP-65 and IP-67 ratings make it ideal for factory, production, and aircraft control applications. It can also be used for general instrumentation and metering in the mining or oil-and-gas industry. Additionally, the meter also displays rotating shift accumulations, making it useful in safety critical applications.

Working Principle

The 99778714 hour meter utilizes digital inputs to count the number of hours that have elapsed since the start of its operation. It can also be used to count pulses. The meter reads its inputs and accumulates the data to a non-volatile memory. This memory keeps a record of the total working hours, even when the meter is powered down. The meter’s display displays an accumulative total as each hour passes and can also be reset to zero at any time. The meter also has a backlight display for night-time readability and durability.

Conclusion

The 99778714 is a versatile panel meter designed for use in industrial applications. It is designed to count, measure, and display hour accumulations as well as other external pulses. The meter’s NEMA-12/4X enclosure provides protection from dust, viruses, and liquids while its IP-65 and IP-67 ratings make it ideal for factory, production, and aircraft control applications. Additionally, the meter’s rotating shift accumulations make it useful for safety critical applications.
