Yokogawa 100-0-100 Field Amps Meter

What is the Yokogawa 100-0-100 Field Amps Meter?

The Yokogawa 100-0-100 Field Amps Meter is an analog electrical measuring instrument designed for AC measurements within a symmetrical range of –100 to +100 amps. Unlike single-direction meters, this bi-directional configuration makes it ideal for systems where current flow can take place in either direction, which may be common, for example, in marine generators, battery charging systems, and DC motor control circuits.

This meter, from Yokogawa, the global leader in measurement and industrial automation, offers reliable and repeatable readings even in quite harsh working conditions. Its robust construction, clear scale, and stable pointer movement make it suitable for continuous monitoring of electrical parameters.

Key Features of the Yokogawa 100-0-100 Field Amps Meter

1. Bi-Directional Current Measurement

The symmetrical scale (100-0-100) allows for measurement of both forward and reverse currents, and provides complete visibility of the system behavior, especially in power distribution and charging systems.

2. High Accuracy & Stability

Calibration of a Yokogawa meter is very accurate, with stable indications. Even under voltage fluctuations, vibrations, and temperature changes, this meter performs very well.

3. Robust Industrial-Grade Build

With its resistant casing, strong front glass, and corrosion-resistant inner components, it is designed for the most challenging industrial and sea environments.

4. Clear Analog Display

It features a large, easy-to-read scale so technicians can quickly interpret readings for better safety and operational efficiency.

5. Compatibility with CTs (Current Transformers)

The meter can work with external CTs to operate in high-current applications, increasing its versatility across many system types.

6. Low Maintenance Requirement

Analog meters require little maintenance compared to the digital ones, thus being cost-effective for long-term usage.

7. Dependable Mechanical Motion

The movement of this pointer is smooth, and it’s responsive-the real-time insight of current variations.
