Overview
Details

The AC&M microprocessor digital panel meters are divided into two categories: one for power system application purposed, and the other is for industrial process measuring. For power system is an AC conversion to DC analog or RS-485 digital measure signal, application for Voltage, Current, Watt, Var, Watt-hour, Var-hour, Power Factor, and Frequency. For industrial process is a DC signal conversion to analog or digital signal such as DC-to-DC, temperature, load cell, speed, rotary, level etc.. These two kinds of digital meters have wide range applications and come in various types suitable to many application specifications, and independent isolating output. AC&M has designed a single input but combined with a digital display meter/transducer output and setting alarm function into one case, also provided high isolated ability for fault protection different from digital multi-meters in that they are used especially for single function, single range measurement. A wide range of equipment and analog to digital conversion in highly accurate digital measurement.

Recently, a digital meter combined with analog or digital output and two Hi-Lo setting relay is a trend of modern multi-function design concept. The traditional analog output has 4~20mA or 1~5V etc.. For more field useful purpose, RS-485 digital output is a necessary equipped. A digital meter relay consisting of a digital panel meter with a comparison function using digital switches has been developed. AC&M’s digital meters combined with unique display/switch relay and high isolated transducer together. Thereby enabling not only the reading of normal values, but also the comparison of large, medium and small values.

The meters have system output function that converts analog signals from sensors to digital signals for direct input to equipment such as computers, recorders computing unit to facilitate recording and automatic control.

AC&M can provide a number of digital panel meters to meet a wide range of applications through reliable design and reality control based on long experience with digital techniques. This is support by extensive and rigorous past production testing that is part of our quality-assurance control system using standards that are directly traceable to national standards. This quality assurance system is backed by an equally extensive and experienced after sales service.
