Description:

Accurate measurement and temperature control are necessary in production and scientific experiment. To accurately measure and control temperature, the characteristics and measuring method of all sorts of temperature sensor must be known firstly, therefore, the characteristic measurement of temperature sensor is one of important experiments in colleges and universities.Temperature sensor characteristic laboratory apparatus is possessed of the following advantages:

1. Adopting TCF708 intelligent controller for copper dry well, which is high in accuracy, large area of constant temperature, small in volume, easy in operation and firm in structure;

2. Equipped with constant current source, dc bridge and digital voltmeter, with which the temperature characteristics of platinum resistance and other thermal resistances (such as thermistor) can be measured in two different ways;

3. Dry well contact thermostat is allowable to insert four test temperature sensors at the same time. Under the same temperature condition, several sensors can be measured in electrical parameter synchronously, which can improve the experiment efficient greatly.

EXPERIMENTS:

Temperature sensor characteristic.
