# K-PT

Our K-PT module is designed to connect PT100/1000 sensors to a K-Box or K-AN8 voltage measurement device that normally cannot support these sensors. The powered K-PT module enables PT100/1000 sensors to be connected via the D-Sub 9 terminals and will output the signal voltages to an Analogue measurement device.

Calibration and sampling rates can be configured using the freely distributed K-Cal software.
