Kaman is a world wide leader in the design and application of inductive technology for non-contact displacement sensing. Our technology is a key source of precision sensing components for OEMs and end users in both commercial and defense industries. Kaman''s eddy current displacement sensors are versatile high performance systems that can be modified, adapted and customized to meet nearly any application requirement.

Demonstration of Kaman''s extremely high-resolution sensor to detect minute movements of conductive material

Economically check 100% thread presence or absence on parts with Kaman''s ThreadChecker. Non-contact application-specific sensors designed to check thread presence or absence. Kaman''s improved ThreadChecker consists of a single electronics module compatible with any probe/material combination. Designed specifically for in-die use, it provides rugged, reliable verification of thread presence or absence in nearly any electrically conductive material. With Kaman''s proven eddy current technology at its core, threads can be checked regardless of part cleanliness, reducing the cost of implementation.

Kaman''s GMS-750 RS or Gapchecker is specifically designed to measure rotor-stator gap in large-scale power generation applications. Our proven eddy current sensor technology is incorporated into an easy-to-use turnkey instrument that eliminates operator dependent variations in collected data and dramatically reduces the overall time required to align the rotor to the stator.

Kaman''s KD-2306 is a multi-purpose non-contact linear displacement measuring instrument.

Kaman Sensors for Offshore Subsea Oil & Gas. Multi-purpose non-contact sensors for remote condition monitoring. Measure vibration, temperature, rotation direction and speed. Monitor, Maintain and Maximize.

Kaman's extreme environment high precision sensors and displacement measuring systems provide accurate non-contact measurement of conductive surface motion in hostile environments including high temperature, low temperature and high pressure. Applications include: Steam turbine shaft run-out in nuclear power plants, nuclear fuel rod position and vibration, Steam and gas turbines, turbine and rocket engines, Chemical processes, Research projects and High temperature processing.

In an eddy current differential system, the two coils in the inductive bridge are housed in two separate sensors. Rather than one active coil and one reference coil, both sensors contain active coils. These two sensors are usually placed on opposite sides of a target or opposite sides of a target pivot point.

Kaman''s SMT-9700 system uses proven inductive (eddy current) technology to provide extremely high-resolution noncontact position/displacement feedback of virtually any electrically conductive target.

Monitor, Maintain and Maximize. Kaman Sensors provide precise data for power generation condition based monitoring systems crucial to protect operating health, minimize costs, maximize performance and optimize bottom-line results. • Non-contact Position/Displacement sensors • Kaman''s inductive (eddy current) high performance systems can resolve position changes to the sub-atomic nano level. • Our extreme environment sensors are unaffected by high levels of pressure, temperature and situational contaminants.

Kaman''s SC-2440 system operates on a traditional Colpitts oscillator circuit where the sensor acts as the resonating coil for the oscillator.

Differential resolution to a nanometer Differential measuring systems provide exceptional resolution, repeatability, and nulling accuracy for detecting the aligned/centered position of a conductive target relative to a pair of non-contacting sensors. Using the KD-5100 for differential measurement applications, two precisely matched sensors per channel are positioned on opposite sides or ends of a target. In this sensor-to-target relationship, as the target moves away from one sensor, it moves toward the other an equal amount. Output is differential and bipolar. The electronically-matched sensors on opposing legs of the same bridge provide superior thermal stability. Two standard sensor configurations are available. Sensors and electronics packaging can be reconfigured for special customer applications or OEM requirements.
