Using Bulk Metal® Foil Precision Resistors to Calibrate RTD Measurements
Highly stable precision foil resistors trimmed to unique values are used to simulate resistance temperature detector (RTD) measurements at precisely defined tempeartures. Bulk Metal® Foil resistors from Vishay Foil Resistors (VFR) can be trimmed to unique resistance values for use in simulating RTD measurements at precisely defined temperatures. These ultra-low TCR VFR resistors are nearly immune to drift over temperature and time, making them the ideal reference to check against RTD under any operating condition or after any lapse of time. Unique resistance values can be produced in only a few days and with relatively little cost due to a convenient calibration factor built into every resistor.
