A Basic Guide to Thermocouple Measurements

Thermocouples are common temperature sensors used in a wide variety of commercial and industrial applications. While slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range, are selfpowered, and have a fast response time. Their simple construction make them inexpensive and durable. Because of the small sensor voltage and low noise ...

Pilot Thermocouples Flame Sensors for Ovens, Ranges, Stoves

Pilot thermocouples are essential parts of your equipment because they measure your oven’s temperature and ensure foods are being cooked appropriately. It’s also important to have properly operating flame sensors, which confirm that the pilot light is lit whenever the gas valve is open. Ultimately, if any of these parts are broken, your oven may be unsafe to operate and even more issues ...
