Finger Pulse Transducers
Finger Pulse Transducers use a piezo-electric element to convert force applied to the active surface of the transducer into an electrical analog signal.
Finger Pulse Transducers use a piezo-electric element to convert force applied to the active surface of the transducer into an electrical analog signal. They are ideal for use in the classroom to study heart rate.
Pulse Transducer (DIN)
- Connects directly to a PowerLab Pod Port (DIN) analog input
- The transducer is kept in place using a hook-and-loop fastener around the finger when measuring finger pulse
- Detects expansion and contraction of the finger circumference, due to changes in blood pressure
- Typical output is 100 mV output for finger pulse (ranges from 20 mV to 500 mV depending on person)
