9.1.2 Calculating a Temperature Coefficient
A temperature coefficient
α
(g/cm
3
/K) is needed for the calculation of some measuring
units at a certain reference temperature.
Baumé
α
(g/cm
3
/K)
Degrees Baumé at 60 °F.
The measuring range is 0 to 100 °Baumé.
Temperature influence is compensated by
the set temperature coefficient
α
.
For determining degree Baumé there are
two different calculation methods
depending on whether the density is
above or below the density of water.
Depending on the density of the
measured liquid, DMA 35 automatically
switches between the two calculation
methods.
H2SO4 H2SO4 % w/w Concentration of sulfuric acid or battery
acid in % by weight.
The measuring range is 0 to 70 % w/w.
H2SO4 @ 20 °C Density of sulfuric acid or battery acid at
20 °C.
The measuring range is 0.8 to 2 g/cm
3
.
Sugar Brix Degrees Brix (sucrose concentration in %
by weight).
The measuring range is -10 to 85 °Brix.
Extract (°Plato) Degrees Plato.
The measuring range is -10 to 85 °Plato.
Custom
Functions -- Optional custom functions. Contact your
Anton Paar representative to obtain a
custom function.
Period -- Period value of the oscillator at the
measuring temperature.
Raw data -- Period value and resistance of the
temperature sensor (only for service
purposes).
