Electronics analog analog displacement displacement output output sensor Sensor system systemKAMAN PRECISION PRODUCTS SC-2440 off the shelf, self-contained analog output displacement sensor system is suitable for applications featuring high-precision automated assembly, OEM applications with on-board computing power, and any application with high repeatability requirements. Device requires no calibration and the temperature of the sensor is continuously monitored, while the circuit provides a voltage output of 0.5 to 1.2Vdc from 0 to 70°C. This temperature-proportional voltage can be monitored by a microprocessor or PLC for active correction of the displacement output with changing temperature conditions. When used in precision automation applications, the output is as accurate at the beginning of the first shift on a cold January morning as it is at the end of the shift on a hot July afternoon.
