Microprocessor or PLC can monitor temperature-proportional voltage or PLC for displacement output correction with changing temperature conditions.

MIDDLETOWN, Conn. – The Measuring Division of Kaman Precision Products Inc. in Middletown, Conn., is introducing the SC-2440 off-the-shelf, self-contained analog output displacement sensor for high-precision, and high-repeatability applications.

The low-cost SC-2440 requires no calibration and continually monitors the temperature of the sensor. the circuit provides a voltage output of 0.5 to 1.2 volts DC in temperatures from 0 to 70 degrees Celsius.

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.

Additional features of the SC-2440 system include self-contained electronics, submersible IP-67 rugged housing, a compact build, built-in temperature sensor, fixed gain output, reverse polarity, and short circuit protection.

The system also features extremely low hysteresis and performs well with ferrous targets. For more information contact Kaman Precision Products online at
