Axial Type Thermometer
Working Principle
.Bimetallic Strip: Consists of two metals with different coefficients of expansion. When the temperature changes, the strip bends, causing the pointer to move on the dial.
.Liquid-Filled System: A liquid-filled bulb and capillary system expands or contracts with temperature changes, moving the pointer via a mechanical linkage.
Overview
Features
1. Temperature Range: Varies widely depending on the specific model, but can range from -100°C to 600°C or more.
2. Accuracy: Typically within ±1-2% of the full-scale range.
3. Response Time: Generally quick, but varies with the design and medium being measured.
3. Mounting Options: Various mounting configurations are available, including wall, panel, and pipe mounting.
4. Environmental Protection: Often rated with ingress protection (IP) ratings for dust and water resistance.
Applications
. Industrial Processes: Used in industries like chemical, petrochemical, and power generation.
. HVAC Systems: Monitoring and controlling heating, ventilation, and air conditioning systems.
. Food and Beverage Industry: Ensuring proper temperature conditions during processing and storage.
. Pharmaceuticals: Maintaining precise temperatures in production and storage areas.
