Introduction to RTD PT200 Probe
Resistance Temperature Detectors (RTDs) are temperature sensors that operate on the principle that the electrical resistance of a metal changes with temperature. The PT200 probe is a specific type of RTD where the “PT” stands for Platinum, a common material used in RTDs due to its excellent linearity, stability, and high temperature coefficient of resistance. The “200” indicates that at 0°C, the resistance of the platinum element in the probe is 200 ohms.
RTD PT200 probes are widely used in various industries such as chemical processing, food and beverage, pharmaceuticals, and HVAC systems.
