The Gravity CT1780 is a cold-junction compensated thermocouple amplifier that makes monitoring extreme temperatures from -270℃ to +1372℃ straightforward and scalable. It accurately digitizes signals from a K-Type thermocouple, providing 0.25℃ resolution, and transmits the data over a simple 1-Wire communication bus. This 1-Wire protocol allows multiple sensors to be daisy-chained on a single data line, perfect for monitoring various zones in industrial ovens, ceramic kilns, or scientific flame analysis. An integrated DIP switch further simplifies identifying individual sensors in a multi-point network, making complex setups manageable.
