The KD-5100 differential impedance transducer from Kaman Precision Products provides reliability, repeatability and exceptional resolution in detecting a conductive target’s position relative to non-contacting sensors.
The transducer system is offered with 15N or 20N sensors. It has a sensitivity of up to 10 V/mil and has 5x10-6”/month long-term stability. The KD-5100 is compact and measures 2x2.12x0.75”. It has a rugged construction and a MTBF of 238,000 h in a reliable environment and over 55,000 h in a tactical environment. The transducer typically consumes less than 2 W of power at ±15 Vdc.
The KD-5100 has two perfectly matched sensors per channel that provide resolution to a nanometer and do not contact the target during measurement. They are located on the ends of a target or on the opposite sides for differential measurement applications. The sensor output is bipolar and differential.
The company utilizes MIL-SPEC components and manufactures the transducer conforming to MIL-H-38534 specifications. For cryogenic applications, Kaman builds a different version of the 20N sensor, which provides optimum performance at 70° K in liquid nitrogen.
