Panel Meters - Counters, Hour Meters

The LH24-F-HM-AL is a panel meter that is part of a range of counters, hour meters, and other meters designed for indoor use in industrial, commercial and electrical construction applications. It is simple to install and easy to use, and is extremely reliable.

What is the LH24-F-HM-AL Used For?

The LH24-F-HM-AL panel meter is used to measure and display the elapsed time for various applications. It has a range from 0 to 4999 hours, 59 minutes, 59 seconds, and it is capable of accumulative measurement of the total triggered time in "stop mode." A reset switch allows the user to reset the measurement back to zero or to a pre-set value.The LH24-F-HM-AL is suitable for a variety of applications, including: machine maintenance monitoring; energy control; tracking running time of pumps or motors; logging production or maintenance cycles; and as a flag timer in security systems.

Advantages

The LH24-F-HM-AL is incredibly reliable. It is designed to be highly resistant to shock, vibration, and electrical interference, and has an extremely long life expectancy. This panel meter is also energy-efficient. It has low power requirements and does not generate any electrical noise, which is ideal for use in sensitive environments.The LH24-F-HM-AL is also incredibly easy to install. It features simple wiring and a compact design, and it can be mounted on any location on a panel with no additional hardware needed.

Working Principle

The LH24-F-HM-AL incorporates an incremental encoder, which is a device used for measuring angular motion and counting input signals. The encoder measures the rotation of a shaft or axle, and converts that movement into electrical signals. These signals are then used to move the needle or LED on the panel meter to indicate the elapsed time.The encoder works by using a slotted wheel and a light source. The wheel has a series of slots cut into it which are spaced equally around its circumference. A light source is positioned behind the wheel and the light passes through the wheels slots when it is rotated. The slots then block the light intermittently when the wheel turns, which generates a series of electrical pulses. The number of pulses is counted and used by the panel meter to indicate the elapsed time.

Conclusion

The LH24-F-HM-AL Panel Meter is a versatile and reliable meter for measuring and displaying elapsed time. It is ideal for a wide variety of applications, from machine maintenance monitoring to security systems. Additionally, it features a simple wiring system, a compact design, and low power requirements, making it simple to install and energy-efficient. With its long life expectancy and extreme resistance to shock, vibration, and electrical interference, the LH24-F-HM-AL Panel Meter is an invaluable tool for industrial, commercial, and electrical construction applications.
