With its user-friendly design and high-quality components, it delivers accurate readings in the harshest of environments.
The GE AW-91 Panel Mount AC Ammeter is a popular choice for measuring alternating current (AC) amperage in the range of 0-40 amperes. Here are some pros and cons of purchasing this panel meter:
**Pros:**1. Reliable and accurate measurement: With a full-scale deflection of 90 microamperes, the GE AW-91 provides precise and reliable amperage readings for various electrical applications.
2. Durable construction: The meter features a rugged die-cast aluminum housing, making it suitable for industrial environments and ensuring long-lasting performance.
3. Easy-to-read scale: The large, bright, and easy-to-read scale makes it convenient for users to monitor the amperage levels at a glance.
4. Adjustable range: Users can select between various ranges for better measurement flexibility: 0-40, 0-20, 0-10, or 0-5 amperes.
5. Fuse protection: This panel meter incorporates a built-in 3A fuse to protect the meter from overcurrent and potential damage.
**Cons:**1. Limited functions: The AW-91 is a dedicated ammeter, lacking additional features like a voltage or resistance measurement or a holding function.
2. Requires an external power source: The meter does not have a internal power supply and requires a power source (typically via a 120VAC or 24VDC power supply) for operation.
3. Heavy for its size: Despite the compact design, the GE AW-91 is relatively heavy, weighing approximately 0.65 lbs (0.29 kg), which may affect the overall weight and balance of the instrument panel.
**Conclusion:**In summary, the GE AW-91 Panel Mount AC Ammeter is a reliable and accurate instrument for measuring amperage in industrial settings. Its heavy-duty construction, large scale, and adjustable range provide excellent functionality for various applications. However, it has its limitations, such as requiring an external power source, and the absence of additional features like voltage or resistance measurement.
If you're strictly looking for an ammeter and don't need extra functions, the GE AW-91 is a strong contender for your consideration.
**Recommendation:**If this meter suits your specific needs and you can accommodate its relatively heavy weight and the requirement for an external power source, the GE AW-91 Panel Mount AC Ammeter would be a worthwhile investment for your electrical monitoring applications.
