SensorTool is a powerful app that provides context to the interpolation of values. The primary use for this app is to support technicians who troubleshoot and calibrate complex systems which use transducers and logic controllers. This app will be useful to Crane and Heavy Equipment Technicians, Instrument and Electrical Technicians as well as a variety of users who use interpolation with any frequency. Users can create and store custom labels as well as create custom sensors or scenarios for repeat-ability when diagnosing and troubleshooting common systems. The app can also be used as a convenience to engineers and students who need to frequently and conveniently interpolate values with a linear relationship.
