Lab #10
Electrical Transducers
Transducers
• Any device that translates a physical
property into an electrical one (or vice
versa)
– Thermistor – changes temperature into
resistance
– Photoresistor – changes illumination into
resistance
Lab Activities
• Activity #1 – Temperature Measurements
– Uncompensated
– Using DMM special probe (see data sheet in
class folder)
– Compensated (with linearizing resistor)
• Activity #2 – Illumination Measurements
– Resistance measurements
– Instrumentation amplifier (DC and AC outputs)
