New VPG RTD simulator

 Vishay Precision Group Inc. announced that its Vishay Foil Resistors brand (VFR) has introduced a new Bulk Metal® Foil RTD Simulator resistor with built-in climate control. Designed to simulate resistance temperature detector (RTD) PT-100 and PT-1000 outputs for the calibration of RTD instruments, the device features a low nominal TCR of ±1 ppm/°C from -55°C to +125°C, +25°C ref., and load-life stability of ±0.005% after 2,000 hours of rated power at +70°C.
