Pyromation
RTDs Resistance Temperature Detectors In operation, a small excitation current is passed across the element, and the voltage, which is proportional to resistance, is then measured and converted to units of temperature calibration. The RTD element is manufactured by winding a wire (wire wound elements) or plating a film (thin film elements) on a ceramic or glass core and sealing the element within a ceramic or glass capsule. Since most RTDs have a low initial resistance, often 100 ohms, and have a small change in resistance per unit...
