Non-contact Proximity Measuring System

Kaman’s KD-2446 non-contact high-precision measuring system utilizes eddy currents, operating on the principle of impedance variation caused by eddy currents induced in a conductive target by a sensor coil. This technology is capable of sub-micro inch resolution. The KD-2446 may be used in a variety of applications using target materials such as ferrous steel, stainless steel or aluminum. Applications for the KD-2446 include displacement, vibration, sorting and event capture. The KD-2446 offers resolution to 12 micro inches and opto-isolated switched output for process control, making it ideal for interfacing to PLC inputs, counters, timers or alarm circuits. The switch is integrated directly within its simple unit, eliminating the need to purchase additional equipment or wire into other components. Key elements of the KD-2446 include variable voltage input (12 to 24 volts DC); temperature tolerant sensors (up to 400°F); high speed (10KHz analog output, 3.3KHz switched output); very low switching hysteresis (< 1% on ferrous targets) and RoHS compliant. The KD-2446 is ideal for RPM sensing in harsh environments.
