Introduction

Ka SMU-9000 measuring systems use inductive (eddy current) technology to measure position without contacting the target. SMU-9000 measuring systems are ideally suited for applications requiring high resolution and economical performance-to-price ratio. Based on Kaman’s proprietary Pulse Width Modulated electronics, the SMU-9000 systems incorporate the latest surface-mount components with printed circuit board designs. The use of pulse width modulation techniques virtuall y eliminates the noise of traditional linear amplifiers, thereby “unmasking” position/motion sensing down into sub-atomic dimensions. This technology requires only simple, single ended supply voltage and low power circuitry.

SMU-9000 Configurations

The SMU-9000 measuring system is available in several configurations. These configurations include: Singl e Channel, Dual Channel, Three Channel, and Four Channel systems shown in figures 2 through 4. The system electronics is housed in an enclosure made of die cast aluminum or poly-carbonate material. Sensors for the SMU-9000 come in a wide variety. The selection of a specific sensor is dependent upon the application in which the system is used.

Power Supply Requirements

The critical circuit voltages needed for operation of the SMU9000 are internally regulated. Therefore, any single ended DC voltage power supply which can furnish from 6.5 to 30 volts at 20ma per channel may be used.

Note: Avoid using switching power supplies if high resolution (low noise) output is required.

The output amplifier runs directly from the supply voltage (positive) and an internally generated negative voltage. The system can be calibrated to have an output voltage swing anywhere from -5 volts to within 1.5 volts below the supply voltage. T ypi cal output voltage ranges and the r equired input supply voltages are as follows:

Output Voltage Range Required Input Supply Voltage

-5 Vdc to +5 Vdc Requires a minimum 6.5 Volt supply

0 Vdc to +10 Vdc Requires a minimum 11.5 Volt

supply

0.2 Vdc to 3.5 Vdc Requires a 5 Volt supply and special 3.5 Volt internal requlator to achieve minimum power drain of 40 mW per channel

-10 Vdc to +10 Vdc

balanced differential
