... Unlike other sensors the LM135 has a linear output. Applications for the LM135 include almost any type of tem- perature sensing over a −55˚C to +150˚C temperature range. The low impedance and linear output make interfac- ing to readout or control circuitry especially easy. The LM135 operates over a − ...

... Thermal Response in Stirred Oil Bath Application Hints CALIBRATING THE LM135 Included on the LM135 chip is an easy method of calibrating the device for higher accuracies. A pot connected across the LM135 with the arm tied to the adjustment terminal allows a 1-point calibration of the sensor that corrects for inaccuracy over the full temperature range ...
