Fast Response Temperature Probe

The TEEMSS Fast Response Temperature Probe is based on an earlier design done for the Data and Models project at CC. The active sensor is a Type E thermocouple made of wire 0.010" in diameter. The two ends of the thermocouple wire are soldered together to create a very low thermal mass temperature probe. The sensor will return to 90% of equilibrium after 30s in still air. The range is -50 to 110 degrees C with a resolution of 0.1 degrees. The cold junction of the thermocouple is compensated with an analog output IC temperature sensor.

Returning to equilibrium in still air

The figure above shows how quickly the sensor returns to equilibrium in still air after being heated 10 degrees. After 30s it was 90% of the way to the still air equilibrium temperature.
