The Temperature Measurement Educational unit 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
