The Temperature Measurement Educational unit (TD-003) designed to demonstrate the different temperature measurement procedures. The trainer is composed of different temperature sensors such as liquid thermometers, bimetallic thermometers, thermocouple, Pt100 and NTC thermistor.

  • different temperature measuring methods.
  • The temperature sensors being studied are attached to a height-adjustable device above the experimental tank.
  • Temperature sensors equipped are liquid thermometer, bimetal thermometer, Pt100, thermistor (NTC), type K thermocouple.
  • A fan is included to ensure almost constant ambient conditions.
  • A second tank with electronically controlled heater supplies water temperatures up to approx. 80°C.
  • The heated water at a specified temperature is fed into the experimental tank.
  • By lowering the height-adjustable device, the temperature sensors are immersed in the water and the temperature measurement begins.
  • The measured values can be read as analogue or digital values.
  • A 3-channel line recorder can record the measured values of the electronic temperature sensors continuously over time and thus also document the different time response.
  • Defined temperature jumps and steady and transient temperature behavior can be studied.
  • Both tanks are equipped with stirring machine
