Temperature Ratings For Heaters Bonded to Aluminium
Product catalog summary
Overview: This document provides technical specifications for temperature ratings of heaters bonded to aluminium plates, produced by Holroyd Components Ltd. The data is presented for a flat element vulcanised onto a 1.5mm aluminium plate, with measurements taken in a steady state condition at an ambient temperature of 20°C in still air.
Specifications: The document lists specific heat output in watts per square centimeter (Watts/cm²) and the corresponding surface temperature in degrees Celsius (°C). The data is divided into two tables based on the range of heat output.
Table 1: Higher Heat Output
- Ranges from 0.750 Watts/cm² at 238°C to 2.000 Watts/cm² at 370°C.
- Incremental increases in heat output result in approximately 10°C increases in surface temperature.
- Ranges from 0.750 Watts/cm² at 238°C to 2.000 Watts/cm² at 370°C.
- Incremental increases in heat output result in approximately 10°C increases in surface temperature.
Table 2: Lower Heat Output
- Ranges from 0.050 Watts/cm² at 40°C to 0.700 Watts/cm² at 230°C.
- Smaller increments in heat output result in varied increases in surface temperature, with larger temperature jumps at lower outputs.
- Ranges from 0.050 Watts/cm² at 40°C to 0.700 Watts/cm² at 230°C.
- Smaller increments in heat output result in varied increases in surface temperature, with larger temperature jumps at lower outputs.
Key Observations:
- The relationship between heat output and surface temperature is linear within each table.
- Higher heat outputs result in significantly higher surface temperatures, indicating efficient heat transfer properties of the aluminium plate.
- The relationship between heat output and surface temperature is linear within each table.
- Higher heat outputs result in significantly higher surface temperatures, indicating efficient heat transfer properties of the aluminium plate.
Applications: These specifications are critical for designing heating systems where precise temperature control is required, such as in industrial or laboratory settings.
