An
Electrical contact bimetal thermometer combines mechanical temperature measurement with electrical signaling, offering a versatile tool for both local indication and automated control in industrial applications. This device integrates a bimetallic strip mechanism with electrical contacts, enabling it to detect temperature changes and trigger alarms or control circuits when predefined thresholds are exceeded.
Working Principle
At its core, the thermometer uses a bimetallic strip composed of two metals with different thermal expansion coefficients. As the temperature rises or falls, the strip bends due to the differential expansion, causing a pointer to move across a calibrated scale for visual temperature reading. Simultaneously, the mechanical movement actuates one or more electrical contacts. These contacts can be set to close or open at specific temperatures, completing or interrupting an electrical circuit. This action can activate alarms, shutdown systems, or control heating/cooling equipment.
Key Features
