Using a built-in voltage to current converter, the analog voltage output from the capacitive sensor is transformed into a 4-20mA current output. The output signal span is ±8mA centered about 12mA bias (zero-g offset). The accelerometer thus outputs a 4-20mA current signal that is proportional to the overall acceleration and the sensor can readily interface to the existing PLCs, process control and predictive maintenance equipment. Description ASC’s current output sensors, CS series, are available in two versions: LN (low-noise) and standard (high bandwidth). These sensors are used typically in industrial environments with strong electromagnetic interference and in applications demanding no loss in transmission of acceleration data over long distances. The ASC CS series features an anodised aluminium housing, which is light-weight and provides case isolation against ground loops. The sensor sensitivity and bias is extremely stable over a wide temperature range from -20°C to +70°C. The CS series is available in uniaxial (ASC CS1711LN, ASC CS1721), biaxial (ASC CS1511LN, ASC CS1521) and triaxial (ASC CS1611LN, ASC CS1621) configurations.
