Panel Meters - Counters, Hour Meters – 90208-26 application field and working principle

The 90208-26 application field and working principle refers to a type of instrument known as a panel meter. A panel meter is composed of counters, hour meters, and other components used for display and measurement of various single-phase and three-phase electric parameters.

Counters are used to accumulate or count the events, or input pulses, in order to measure or monitor the performance of a system or device.

In 90208-26 application fields, the counters are usually designed to count pulses from digital pulse generators, rotational speed sensors, frequency meters, and other sources. The counters have a wide selection of input signals, including sinusoidal alternating current (AC), direct current (DC), frequency, and binary coded pulses, as well as a variety of different types of output signals. Counters are used to measure frequency, revolutions per minute (RPM), general pulse rate, accumulative electric energy, and elapsed time.

An hour meter is used to measure and record the operating time of an appliance or piece of equipment. It is an instrument with a counter that is pointed at a stopwatch or timer. This type of meter is typically used to measure the length of time the appliance or equipment has been in operation. They can measure from one to sixty hours, depending on the model.

The 90208-26 is used in applications where accuracy, reliability, and minimal maintenance costs are important. It features an RF receiver to gather and log information as well as a large graphic display showing the personnel’s status. This device has a dual clock for precise time measurement as well as an auto start and stop timers. It also includes a large memory and a printout function to save data for later review.

The 90208-26 employs a variety of circuitry and components to provide precise performance and measurement. Its operation is based on a phase-locked loop circuit that imparts an oscillator signal to a counter circuit, which continuously calibrates and corrects the panel meter’s input for maximum accuracy. The counters are constructed with solid state, digital circuitry and feature input sensitivity and range adjustment for increased accuracy and resolution.

In addition, the 90208-26 features nine different selectable scales for measuring frequency ranging from 0.1 to 150 kHz. The device also has an adjustable amplitude selector for choosing the appropriate voltage level. The 90208-26 is also able to provide the user with an adjustable hysteresis feature to avoid overlap of different measurements.

The 90208-26 is an ideal choice for monitoring, controlling, and measuring power quality and frequency. Its features and accuracy make it a great device for a range of applications, from industrial and medical equipment, to appliances, and other consumer products.
