An industrial customer wanted to monitor the power into a large oxidation oven, and tie that information into his existing distributed control system (DCS). He needed to measure three phase currents (to detect unbalances and phase loss), plus total kW. After considering several options for a power transducer with digital communications, he chose instead to use four analog 4-20mA loops to feed the DCS.
The Crompton INT1560 Energy Transducer has the required inputs and outputs. It measures 50 electrical parameters and provides both digital and analog outputs. Initial setup can be done through a plug-in display unit or through the RS-485 Modbus port (using Crompton's free configuration software). This rugged unit has an extended temperature range and enhanced noise immunity, so it can be installed on the plant floor.
