Thermostatic Control and Temperature Sensor Laboratory Equipment

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing an essential laboratory apparatus designed to bridge theory and practice in the studies of thermodynamics and electronic instrumentation This instrument is specifically developed for the characterization and scaling of temperature sensors serving as a core component in general physics curricula and engineering programs at leading universities worldwide This tool provides a solid practical foundation for students to understand how temperature is measured controlled and applied in real-world systems

The platform offers a series of in-depth experiments centered on modern temperature sensors like the AD590 current integrated sensor Students can actively measure and apply the relationship between output current and temperature calculate the sensor's sensitivity at freezing point and understand its volt-ampere characteristics to determine the minimum linear service voltage range These experiments build an intuitive understanding of how sensors work at the circuit level

In addition to integrated sensors this apparatus also facilitates the exploration of semiconductor thermistors Users can measure the relationship between the resistance and temperature of a thermistor which is a key component in many commercial and industrial applications Furthermore they are challenged to find its empirical formula from the collected data a valuable exercise that combines physical measurement with data analysis and mathematical modeling

One of the most educational features of this equipment is its ability to support a design-and-install project Students can design and assemble their own digital Celsius thermometer using the provided AD590 sensor a resistance box a digital voltmeter and a DC source This hands-on experience is crucial in teaching the fundamental principles of instrumentation design and how individual components integrate to create a functional measurement system

Technically this device excels in several key aspects It offers a wide thermostatic control range from ambient temperature down to -80°C with a precise 0 1°C display resolution Its compact design which is safe without mercury pollution or relay noise and equipped with dual digital displays for both set and measured temperatures makes it a highly practical and efficient tool for any teaching laboratory requiring constant temperature control for various physics and chemical experiments
