The Measuring Division of Kaman Precision Products introduced the off the shelf, self-contained SC-2440 analog-output displacement sensor, suited for high-precision and high-repeatability applications. Targeting automated assembly, OEM applications with on-board computing power, and any application with high repeatability requirements, the low-cost SC-2440 requires no calibration.
The temperature of the sensor is continuously monitored, and the circuit provides a voltage output of 0.5 to 1.2 VDC from 0° to 70°C, which can be monitored for active correction of the displacement output with changing temperature conditions. Additional features include self-contained electronics, a submersible IP-67 rugged housing, fixed gain output, reverse polarity, and short circuit protection. The system also features extremely low hysteresis and performs well with ferrous targets.
