Displacement Measuring System suits high-sensor-count applications.
October 28, 2011 -
Featuring 19 in. modular rack format, Model KDM-8206 is based on 3U-by-7T Eurocard module that makes multi-channel displacement, run-out, and position measurements. Module contains inductive bridge and signal conditioning circuits that produce linear voltage proportional to physical displacement of target relative to sensor. User can add channels by installing modular PC backplane boards into empty slots. With coarse and fine calibration controls, system achieves resolution to 10 µin. or better.

Kaman 's New Rack-Mount High-Precision Displacement Measuring System Handles High-Sensor-Count Applications
MIDDLETOWN, CT - In response to the ever-increasing demand for ease of expandability in multi-channel sensor applications, Kaman delivers the new KDM-8206 measuring system in a 19-inch modularized rack format. The user easily adds channels to the system by installing modular PC backplane boards into empty rack or bench-top enclosure slots.
Designed for making high-precision multi-channel displacement, run-out, and position measurements, the KDM-8206 is ideal for high-sensor-count test and development applications in industrial, laboratory, and production facilities. The 3U-by-7T Eurocard measuring module is the fundamental component of this non-contact measuring system, and features auto-synchronization of multiple channels.
The KDM-8206 module contains the inductive bridge and signal conditioning circuits that produce the measurement output, a linear voltage proportional to the physical displacement of the target relative to the sensor. With both coarse and fine calibration controls, the system achieves resolution to 10 microinches or better or 0.01% of full scale. In addition, the KDM-8206 features non-linearity of <1% of full scale, and frequency response of 50 KHz standard, with up to 120 KHz optional. Output signals are single-ended voltage, differential voltage, or 4 to 20mA current.
The KDM-8206 sensors measure ferrous and non-ferrous targets. Kaman offers 21 standard sensors that operate from -67° to 220°F, and ten sensors that operate from cryogenic to 400°F. The inductive eddy current technology on which these sensors are built is unaffected by environmental contaminants such as water vapor, oil, particulates, etc.
Kaman offers three types of enclosures for the KDM-8206 measuring channel: 12-channel full rack, 9-channel mid-rack, and 6-channel half-rack. All Kaman-supplied racks feature 110/220 VAC, 50/60 Hz input power supply, BNC coaxial output connectors for measuring channel voltage outputs, two-position terminal blocks for measuring channel current outputs, and twin BNC connectors for sensor inputs. Optional are meters, rack-to-rack synchronization, and true differential output.
CE marked and RoHS compliant, the KDM-8206 is available immediately from Kaman Precision Products. With all inquiries, Kaman's experienced applications engineers review the customer's performance requirements - considering the calibrated range, linearity, thermal sensitivity, resolution, and repeatability required - and recommend the appropriate configuration for the application.
Kaman Precision Products | Measuring, a division of Kaman Aerospace, has led the industry for over 50 years in solving difficult sensing applications when the target cannot be touched.
