AMI-1MM2

The AMI-1MM2 and AMI-1MU2 indicators from Alco Science are compact, versatile devices designed for use in gas chromatography applications. These indicators are ideal for detecting the presence and quantifying the amount of various gases or volatile organic compounds (VOCs) in a gas stream.

The AMI-1MM2 and AMI-1MU2 indicators feature a robust, reliable design using a UV lamp and an optically-matched filter for increased sensitivity and accuracy. The indicators are available in two versions: AMI-1MM2 for H2, CO, and other reducing gases, and AMI-1MU2 for oxygen and other oxidizing gases.

Both indicators come with a user-friendly analog display, which shows the percentage of the gas being detected in real-time. A built-in automatic baseline stabilization feature ensures accurate readings even in the presence of varying background gas concentrations.

These indicators offer a 3/8 NPT thread connection, making them compatible with most gas chromatography systems. They also feature a short response time and a wide dynamic range, ensuring they can accurately detect gas concentrations from very low parts per million (ppm) to over 100%.

The AMI-1MM2 and AMI-1MU2 indicators are also highly durable, with a rugged housing and a long lamp life. They can operate in a wide temperature range, making them suitable for use in various industrial, laboratory, and research environments.

With their precision, reliability, and ease-of-use, the AMI-1MM2 and AMI-1MU2 indicators are essential tools for anyone working with gas chromatography applications, providing real-time, accurate, and reliable gas concentration readings.

Pros and Cons of Buying AMI-1MM2 and AMI-1MU2 Current Transducers

AMI-1MM2 and AMI-1MU2 are current transducers manufactured by ABB (Asea Brown Boveri). AMI-1MM2 is a shunt type current transducer for current measurement with a burden capacitance of 1 mmu, while AMI-1MU2 is a voltage type current transducer with a burden voltage of 1 mm2.

1.1 High Accuracy: AMI-1MM2 offers excellent accuracy and reliability in current measurement. Its shunt type design ensures precision measurements even in harsh environmental conditions.

1.2 Wide Input Current Range: This transducer can measure and monitor currents ranging from 0.25 A to 5,000 A.

1.3 Rugged Design: The AMI-1MM2 is known for its rugged construction, which can withstand high operating temperatures and demanding environments.

2.1 Foil Shunt Prone to Corrosion: The shunt in the AMI-1MM2 is made of nickel silver, which can be susceptible to corrosion under specific conditions, requiring regular maintenance.

2.2 Shunt Requires Proper Installation: The shunt must be mounted and installed correctly for accurate readings. It is important to follow correct installation procedures to avoid potential issues.

3.1 Flexible Burdening Options: AMI-1MU2 supports broad burdening voltage options, making it suitable for several measurement applications.

3.2 Reduced Cost: The voltage type current transducer typically costs less compared to shunt type transducers like the AMI-1MM2.

4.1 Sensitive to Burden Voltage: The voltage type current transducer's accuracy depends on the burden voltage accuracy and must be closely monitored.

4.2 Temperature Effects: Like all voltage type current transducers, temperature changes can impact AMI-1MU2's performance.

When considering AMI-1MM2 and AMI-1MU2 current transducers, both have their advantages and disadvantages. AMI-1MM2 offers higher accuracy, wide input current range, and ruggedness. However, it may require more maintenance since the shunt is prone to corrosion and needs proper installation. AMI-1MU2 is flexible with burdening options, more cost-effective, and provides easier installation. However, it requires close monitoring of burden voltage, is sensitive to temperature, and may not achieve the same level of accuracy as AMI-1MM2.

If accuracy and reliable current measurements in harsh environments are the top priorities, AMI-1MM2 would be an excellent choice for applications with sufficient budget to cover maintenance. For more cost-conscious applications with acceptable accuracy requirements, the AMI-1MU2 voltage type current transducer could be the preferred choice.
