Panel Meters - Counters, Hour Meters

Panel meters are instruments used to measure and display physical parameters such as pressure, current, voltage, and temperature. Counters, hour meters, and related products are used to track usage and operation parameters. In this article, we will discuss 87620213 application field and working principle.

87620213 is a basic electrical counter with digital internal circuitry that uses contact closure and pulse signals to count. It is designed for applications that require manually counted events. It is ideal for applications in the data acquisition, consumer electronics, and medical/safety markets.

Application Field

Typical applications include counting the number of product manufactured including food and other items assembled on a production line, data acquisition of pulse-controlled systems, and battery-operated equipment. 87620213 also has applications in amusement and gaming industries where it is used to monitor the number of gameplays, and in fire and safety equipment to track the number of times a device has been activated.

Working Principle

87620213 operates on the principle of contact closure or pulse input. The contact input measures the frequency of closures in an electrical circuit. As the frequency increases, the number of closures increases and the number on the display increases. The pulse input measures the number of pulses received over a period of time and displays the result. On both contact and pulse input, the count can be reset from the unit itself or from an external reset remote control.

Once the signal is received, it is registered electronically in the internal circuitry, and the display is updated automatically. The unit can be configured to accept a wide variety of input frequencies ranging from dc to 10 kHz. The display counter measures in intervals of 0.01, 0.1, 1, 10, or 100 units depending on how it is programmed.

87620213 is powered by an internal battery with a life of approximately 10 years and can be wall or DIN-rail mounted for easy accessibility and installation. It requires minimal wiring and can be used in both basic and sophisticated applications. Its protected and durable enclosure offers long-term reliability in harsh environmental conditions.

In summary, 87620213 is a simple, low-cost, and effective device for counting data and usage. It offers an economical solution for measuring and monitoring a wide range of processes and applications. With its wide range of input frequencies, it can cater to most applications.
