The bimetallic sensor technology in the KST401 thermostat ensures accuracy through the precise and predictable properties of its bimetallic strip. Here's how it works:
1-Material Composition: The bimetallic strip is made of two metals with different coefficients of thermal expansion. As temperature changes, one metal expands or contracts more than the other, causing the strip to bend.
2-Temperature Sensitivity: The specific metals used are selected for their sensitivity to temperature changes, ensuring that even small variations in temperature produce measurable deflections.
3-Mechanical Actuation: The bending motion of the strip directly actuates the thermostat's contacts, opening or closing the electrical circuit with high precision. This eliminates the need for intermediate mechanisms that could introduce errors.
4-Calibration and Design: The KST401 is carefully calibrated to maintain a narrow differential of 5°C ±1°C, ensuring the sensor consistently triggers at the desired temperature range.
5-Repeatability and Reliability: The bimetallic sensor's mechanical properties are stable over time, providing consistent performance through repeated cycles of heating and cooling.
This combination of design and material properties allows the KST401 thermostat to deliver accurate, reliable temperature control across a wide range of applications.
