87620212

Panel meters, or instrumentation meters, are devices used to measure - and often display - the values of various electrical and mechanical processes. Many serve as indicators, gauges, or counters, offering the user immediate feedback on a circuit\'s current performance. 87620212 is one type of panel meter that can serve a specialized purpose in certain circuits. This article will explore the application field and working principle of 87620212.

Application

The 87620212 is designed to serve as an electronic hour meter. It measures the amount of time a circuit is on, then displays the total in hours. Hour meters are embedded in motors to show the amount of time each has been running, which can be used to determine the lifespan of the motor, when it should next be serviced, and when it needs to be replaced. This allows a user to anticipate the necessary replacement before any significant failures occur.

The 87620212 can also be used as a digital counter. On watch devices, such as digital cameras or handheld scanners, the 87620212 can be used to count operations, such as the number of photos taken or the number of scans produced. This allows the user to monitor usage and wear and tear of the affected part. Other counters can measure and indicate elapsed time, such as the time in between shifts in industrial applications.

Working Principle

The 87620212 functions using a series of integrated circuits (IC). These ICs are configured to recognize input conditions, such as voltage or current, and display corresponding output values. The 87620212 is designed with a height of 4.6 inches, a width of 2.8 inches, and a depth of 1.6 inches, allowing it to be used in tight spaces. It is also configured in a panel-mountable design, and can be integrated into a larger unit (such as certain watch devices or machines with existing meters).

Power to the 87620212 is provided through a single AAA battery, which lasts up to 200 hours of continuous use. The 87620212 simultaneously measures and stores digital information, so if power is lost, the data is not reset. Additionally, the 87620212 features a liquid crystal display (LCD), which can be used to view readings from two to three feet away.

Conclusion

The 87620212 is an electronic hour meter and digital counter commonly used in many industrial and watch devices. It uses integrated circuits to recognize input conditions and display corresponding output values, and can be used to monitor the lifespan of certain parts and usage of assemblies. The 87620212 is designed to withstand power surges, and the LCD display can be seen from two to three feet away. Altogether, the 87620212 is an ideal choice for anyone interested in monitoring circuit performance.
