Description

The Transducer Fundamentals module guides the trainee through the circuits and devices used to interface computer and control circuits to the outside world. The circuit board includes eight transducer circuit blocks, an oven for demonstrating temperature transducers, an instrumentation amplifier with selectable gain, and a Reference Supply circuit block with computer interface.

Students learn the principles of input and output transducers and how physical quantities, such as heat, position, proximity and force, are converted to electrical signals for detection and processing by computer and control systems.

The circuits found on this module include: IC Transducer, Thermistor, RTD, Thermocouple, Strain Gauge, Capacitance Sensor, Ultrasonic Transducers (Transmission/Reception), and Infrared Controller (Transmission/Reception) This circuit board can be interfaced with the 32-Bit Microprocessor board to demonstrate the principles of data acquisition and microprocessor control of external devices in process control and automation applications.
