Heat Transfer Apparatus

• A benchtop service unit designed to interface to a range of heat transfer Modules
• Provides a variable, stabilised 0-24V DC supply to the heater of the heat transfer accessory, with a current capability of 9 amp
• Provides a drive signal for a proportioning solenoid valve used for flow control
• Provides a control signal to a variable speed blower used for generating airflow
• 10 temperature inputs and conditioning circuits for K-type thermocouples:
  – 9 off, 0-133°C, resolution <0.1°C
  – 1 off, 0-500°C, resolution <0.15°C
• Instrumentation inputs for heater voltage, heater current, air flow, water flow, radiation and light meter
• State of the Art Data Acquisition system for detailed Data Analysis

The 909E Equipment is housed in a high Quality Heat module for heat transfer experiments. It provides control outputs to the accessories, and instrumentation inputs from the accessories.

Outputs:

• A stabilized, variable DC supply to the heater of the heat transfer accessory under evaluation
• Drive to flow-regulation valves
• Drive to the variable-speed air blowers 

Inputs and Instrumentation:

• Temperatures: (up to 10 off, dependent on accessory being used
• Heater voltage
• Heater current
• Heat radiated
• Light radiated
• Air velocity
• Cooling water flowrate
