Annealing procedures for hot-wire sensors of platinum and platinum-plated tungsten have been investigated experimentally. It was discovered that the two investigated sensor metals behave quite differently during the annealing process, but for both types annealing may improve long-term stability considerably. Measured drift of sensors both without and with prior annealing is presented. Suggestions for suitable annealing temperatures and times are given.
对铂和镀铂钨热线传感器的退火程序进行了实验研究。结果发现，在退火过程中，所研究的两种传感器金属表现出截然不同的特性，但对于这两种类型的传感器，退火均可显著提高其长期稳定性。文中给出了未经退火和经过预先退火的传感器的测量漂移情况。还给出了合适的退火温度和时间的建议。
