Yokogawa Counts Per Second Type AB-16 AB-40 DB-16 DB-40

Description:

The Yokogawa Counts Per Second Type AB-16 / AB-40 / DB-16 / DB-40 Panel Meter is used in electrical measurement systems for monitoring pulse frequency or count rate signals. Commonly installed in switchgear, control panels, and industrial instrumentation systems requiring frequency or pulse indication. Maintenance teams and system integrators use this part for replacing legacy meters, monitoring signal rates, or maintaining accurate process indication in industrial environments.

Applications:

The Yokogawa counts-per-second meters in the AB/DB series are commonly used in industrial environments where pulse signals or frequency-based measurements need to be visually monitored. These meters are frequently applied in power plants, marine systems, and manufacturing facilities to measure signals from sensors, tachometers, or flow systems that output pulses proportional to speed or flow. The AB/DB switchboard series is designed for high visibility and rugged environments, making them suitable for control rooms and harsh industrial settings.
