Product Description of K3MA-J Digital process meter
The Omron K3MA-J-A2 Digital Process Meter is a compact and highly dependable panel-mount indicator designed for monitoring and displaying industrial analog signals with excellent clarity and stability. This process meter accepts both voltage and current inputs, allowing it to work with a wide range of field instruments such as pressure transmitters, level transmitters, flow sensors, and temperature transmitters commonly used in industrial automation systems.
Equipped with a bright five-digit dual-color LED display, the unit can show measurements in either red or green illumination. The color-change function helps operators instantly recognize normal and abnormal operating conditions without additional indicators. Large display characters ensure that readings remain visible from a distance, which is especially useful in factory floors and control panels.
The K3MA-J-A2 operates on a safe 24V AC/DC power supply, making it suitable for PLC control panels and low-voltage automation environments. The meter allows easy front-panel configuration, enabling users to scale input signals into meaningful engineering units such as temperature, pressure, or flow rate. Built-in functions such as zero adjustment, averaging processing, and peak value monitoring improve measurement stability when signals fluctuate.
The device also includes relay comparison outputs that can be used to trigger alarms, warning lamps, or control actions when process values exceed preset limits. Its compact panel-mount design reduces installation space, while the protective front panel construction resists dust and moisture, making it appropriate for demanding industrial environments.
Because of its accuracy, simple setup, and strong visibility, the Omron K3MA-J-A2 digital indicator is widely used in manufacturing plants, water treatment systems, packaging machines, and process control applications where reliable real-time monitoring is required.
