Heat sensitive thermometer - 10 ~ + 100 °C, the linear scale

Demo with large electric meter of the instrument is made,the rapid determination of the the temperature of liquid,the gas and solid surface. It is used for a middle school physics teaching demo, normal colleges and universities as essential supporting equipment.

Technical requirements:

1. The temperature measuring range: - 10 °C ~ 100 °C
2. Working voltage: DC 6V
3. Supporting electric meter: demo with large electric
meter sensitivity 500 ua ~ 2 ma
4. The reaction time:no more than 6 seconds.

Structure principle:

This instrument make use of negative temperature coefficient that semiconductor thermistor has, when temperature increases, its resistance decreased, when the temperature drops, its resistance value increases. Using this feature, the thermistor can change line amplifier output voltage. A adjustable potentiometer voltage output, it can adjust the full value of demo electric meter. When electric thermistor resistance changes, also changes in the linear amplifier output voltage, so the current value will change.Meter shows the measured temperature value.
