B-parameter equation (0x80n00:19, entry 0x111)

The B-parameter equation can be used for NTC sensors (thermistors), i.e. RTD elements with negative coefficient k.

Here the coefficient R_T0 indicates the resistance at the temperature T₀, the B-parameter can be taken from the information provided by the sensor manufacturer, or it can be determined by measuring the resistance at two known temperatures.
