自动粘度计测量时间原理-热敏电阻粘度管
Viscometer with thermistor sensors (TC
viscometer)
In the case
of
TC viscometers, glass-coated thermistors serving as sensors are molten in
on
the level of the measurement planes. While the meniscus passes through the measurement planes, the differences in the thermal conductivity properties of air and liquid
lead to a change in the
heat
balance. The thermistors of the TC viscometers are molten
hermetically tightly into
the glass coating of the
viscometer, so that the viscometers located
inside are chemically resistant to all kinds
of substances other
than strong leaches,
fluoric solutions, or c
