The Importance of Temperature Monitoring in your Lab
beta-static.fishersci.comTemperature Measurement Instrument Measurement Accuracy— For temperature and humidity monitoring devices, measurement accuracy refers to the closeness of the value obtained with a particular device to the true value being measured. In practice, this is determined by comparison with a device that has been calibrated against a standard that is

Accurate Temperature Sensing with an External P-N Junction
www.analog.comTemperature Sensing Theory Linear Technology devices use an external bipolar transis-tor p-n junction to measure temperature. The relationship between forward voltage, current, and temperature is: IC =IS e VBE (nVT) –1 ⎛ ⎝ ⎜ ⎜ ⎞ ⎠ ⎟ ⎟ VT = kT q IC is the forward current IS is the reverse bias saturation current VBE is the ...
Components and Methods for Current Measurement
www.vishay.comThe TC R effects can be partially compensated by measuring temperature and correcting the measured voltage with anticipated changes in resistance due to temperature. Often times the TCR for MOSFETs can be as large as 4000 ppm/°C, which is equivalent to a 40 % change in resistance for a 100 °C rise. Generally, this measurement method
