A thermistor leaf thermometer.
An instrument is described which allows measurements of leaf temperature within about 0.3 C. It consists of a special thermistor probe, a small circuit box, and a standard ammeter. The circuit box can easily be fixed to the meter and contains a battery, which passes 0.3 milliampere through the thermistor, and also contains an integrated circuit amplifier, so that the meter reads 20 C full scale...
متن کاملA digitally linearized thermistor thermometer referenced to IPTS-68.
We describe a digitally linearized thermistor thermometer that is accurate to +/- 0.01 degrees C from 0 to 60 degrees C at a wattage of 50 microW and a sampling time of 1 s. It is traceable to the International Practical Temperature Scale of 1968 (IPTS-68). Analog and digital outputs are provided, the latter as ASCII RS-232C. The thermistor is a 10-cm long immersible probe, 1.5 mm in diameter. ...

متن کاملA Generalized Periodic Thermistor Model
The theory of maximal monotone operators is utilized to prove the existence of weak periodic solutions for a coupled nonlinear parabolic-elliptic system.The diffusion term in the parabolic equation contains a Leray-Lions operator.This system may be regarded as a generalized version of the evolution thermistor model.
متن کاملReviving the labial thermistor clip.
The labial thermistor clip was first introduced as a physiological measure of female sexual arousal almost 30 years ago (Henson, Rubin, Henson, & Williams, 1977); however, only a few studies have subsequently reported on its use. The development of the clip was based on the idea that surface temperature reflects changes in blood volume such as what causes genital tumescence during physiological...
