ResistiveInputPoint

A ResistiveInputPoint is a NumericPoint with NrioResistiveInputProxyExt. It configures a UI to read a resistance from 0 to 100,000 ohms. Default configuration provides ohms. If other units are needed, select conversion type of either Linear (for linear response) or Generic Tabular, if non-linear. For details, see Scale and offset calculation (linear) and Non-linear sensor support.

NoteUniversal inputs (UIs) are optimized for resistive temperature sensors in 10K ohm range. Any temperature sensor far outside this range, for example a 100 ohm or 1K ohm type, will have poor resolution—and thus be unusable! In this case, install a compatible transmitter that provides a linear 0-to-10V or 4-to-20mA signal, and use a VoltageInputPoint instead.

The ResistiveInputPoint is pre-configured with a linearCalibration extension, to allow for offset correction. For details, see Linear Calibration Ext.

The ResistiveInputPoint’s Proxy Ext contains only common Nrio Proxy Ext properties. Among these, note that the read-only “Device Facets” property is preset to ohms.
