Thermostatic Control Sensor Laboratory Apparatus
DESCRIPTION / TECHNICAL SPECIFICATIONS
Characteristics
measuring and scaling of temperature sensor are essential contents of heat and
electromagnetism experiments in college general physics, and also an important
experiment newly added to the teaching program of engineering universities in
countrywide.
Features:
►► Small in volume.
►► High accuracy in
temperature control.
►► Without
pollution and noise (have no mercury used and relay as well).
►► Digital display
both for set and measured temperature values. The apparatus is suitable for
measuring the characteristics of all kinds of temperature sensors and the
relation of resistance to temperature of a variety of materials. It also can be
used for physics and chemical experiments acting as constant temperature
apparatus. It is one of necessary experimental apparatus required by the
engineering universities.
Experiments
►► Measurement and
application of ad590 current integrated temperature sensor.
►► Easuring the
relation of output current to temperature of ad590 sensor, calculate the
sensitivity of the sensor and its output current at 0°C;w
►► Design and try
to install a digital celsius thermometer by utilizing AD590 sensor, resistance
box, digital voltmeter and dc source.
►► Measuring
volt-ampere characteristics of AD590 sensor at a constant temperature and find
out the minimum voltage within the linear service range of AD590 sensor.
►► Measure the
relation of thermistor value of semiconductor to temperature and find out
empirical formula of this thermistor.
