Measuring Temperature

Overview

This test procedure is used for measuring temperatures associated with the pressure chamber. Sometimes materials can weaken due to heat and thermal tests need to be performed in order to make sure the materials stay within the correct temperature range.

Caution

Due to pressures involved, this experiment should be carried out behind a safety barrier.

Equipment

  • Air source. This includes pumps, tanks, compressors etc.
  • Pressure gauge
  • Thermometer / thermocouple

Procedure

This is a general procedure for measuring internal temperatures as it will depend on what is being tested and what temperature measuring equipment is available.

  1. Prepare the pressure chamber for the test by mounting it securely and attach it to the air source.
  2. Attach the thermometer or thermocouple to the desired location in the pressure chamber. Where this is located will depend on what is being measured.
  3. Pressurise the pressure chamber and record readings.
  4. Depressurise the pressure chamber.

Notes

  1. It is a good idea to video tape the experiment that includes the pressure gauge and temperature reading for later analysis.
