Moore Industries Millivolt Transmitter MVT/0-1MA/4-20MA/117AC WT

The Moore Industries MVT Millivolt Transmitter is a robust industrial device designed to convert low-level input signals into a standard 4-20mA output for reliable process control and monitoring. This specific model, MVT/0-1MA/4-20MA/117AC WT, features an input range labeled as 0-1 mA (noting potential inconsistency with typical millivolt naming, possibly indicating a low-current or custom millivolt range), an output of 4-20mA, and operates on 117V AC power. The 'WT' designation likely refers to a weather-tight configuration, housed in a Hoffman NEMA Type 4 enclosure for protection against harsh environments like dust, water, and corrosion. Key features include adjustable span and zero potentiometers for easy calibration, electrical isolation to prevent ground loops, and high accuracy for precise signal transmission. It is commonly used in applications such as temperature monitoring with thermocouples, process automation in chemical plants, oil and gas facilities, and power generation systems. Advantages over similar products include Moore's reputation for durability and reliability, with benefits like reduced signal noise and compatibility with legacy systems. Drawbacks may include its analog nature compared to modern digital transmitters, potentially requiring more maintenance. The unit appears used but in good condition based on visual analysis, with no visible damage, and includes a caution label for safe handling. Overall, it provides cost-effective signal conditioning for industrial assets.
