Fluid Viscosity
When the application involves highly viscous fluids,
the fluid immediately around the thermistor probe
will heat up thus producing an incorrect result when
compared with the temperature of the bulk of the
fluid. This effect would be shown as a levelling of
the voltage/temperature characteristic at lower
temperatures. Fluids which produce sedimentary
deposits can increase the thermistor response time.
