In this webinar, we will introduce our 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 RTD Simulator 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. The RTD Simulator provides a faster, easier, and far less expensive alternative to decade boxes and electronic simulators for the calibration of transmitters, controllers, data acquisition, process control, and lab equipment in the field, shop, or control room. Each RTD Simulator comes with certification and features its specified temperature simulation — anywhere from -200°C to +850°C — clearly printed on the device for easy identification. The climate control capabilities of the RTD Simulator are provided by the inherently low absolute TCR of Bulk Metal Foil resistors, which itself results from two predictable and opposing physical phenomena within the composite structure or the resistive alloy and its substrate. The first is that the resistance of the alloy increases with the temperature. The second is that the coefficient of thermal expansion (CTE) of the alloy and substrate are different, resulting in a compressive force on the alloy when the temperature increases and a consequent decrease of the foil resistance. The two effects occur simultaneously, resulting in an unusually low predictable, repeatable, and controllable TCR. The webinar will feature a combination of slides and short videos to demonstrate the features and benefits of this new product.
