Digital Differential Impedance Transducer (Digital DIT) DDITThe Measuring Division of Kaman Precision Products announces the release of a new eddy current measurement system, the Digital Differential Impedance Transducer (DDIT). The DDIT is designed to provide a digital interface for high speed eddy current measurement systems, with resolution in the micro-inch range, at bandwidths as high as 60 kilohertz (kHz). It is ideal for use in applications for fast steering mirrors, magnetic bearing active control, shaft vibration, image stabilization, and adaptive optics. Using a standard 9D connector for reading data, power, and control signals, the system operates from a single power supply with a voltage range of 8-28 volts. The DDIT is available in three configurations: The Digital System is designed to interface directly to an embedded controller with a master serial peripheral interface (SPI) bus. The ANA (analog) System provides linear analog voltage, with a full range output signal of 0-5 VDC with a null position of 2.5 VDC. The FE System is designed for field-programmable gate array (FPGA) interface for high speed operation, with data rates as high as 128 kHz, 48 bits of data, 60 kHz bandwidth, and no internal firmware.
