Web15 de jan. de 2024 · When you talk about a hospital-grade thermocouple, it’s highly likely you’re seeing a thermocouple at work. Even other medical equipment that requires detection, diagnosis, and even treatment often uses the temperature sensor. Usually, these are miniaturized to produce highly-reliable temperature readings in heat-critical set-ups. Thermocouples are suitable for measuring over a large temperature range, from −270 up to 3000 °C (for a short time, in inert atmosphere). Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, other industrial processes and fog machines. They are less suitable for applications where smaller temperature differences need to be measured with high accura… WebHence the term, 'thermocouple'.
