Hair tests are more likely to detect regular than occasional marijuana use. One study found that 85% of daily users tested positive for marijuana, versus 52% of occasional smokers (1-5 times per week). Ingested cannabis was less likely to be detected than smoked marijuana [ 01 ].
For the similarly named concept in computer science, see Finite state transducer. A transducer is a device that converts one form of energy to another. Usually a transducer converts a signal in one form of energy to a signal in another. Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
One of the most frequently used temperature. transducers is the thermocouple. Thermocouples. are very rugged and inexpensive and can operate. over a wide temperature range. A thermocouple is. created whenever two dissimilar metals touch and. the contact point produces a small open-circuit.
