Linearisation
shown in ( Figure L 21 ), with the linearisation of a displacement transducer by means of two coils, S1 and S2, in a regenerative circuit.
Velocity of sound pressure waves
is 333 m/s. In mineral oil it is dependent on its air content. In pure oil it is approx. 1 500 m/s and drops rapidly with undissolved air in the oil. For this reason an average value of 1 300 m/s is used
Kinematical viscosity v
(°E), and then in stokes or centistokes (cSt), but is now given in m 2 /s or mm 2 /s. cSt can be converted as follows: 1 cSt = 1 mm 2 /s
Transmission speed
of time (DIN 19 226 Part 5). At a cycle frequency of 1 kHz, in the case of series data transmission, this results in a transfer of 1,000 Bit/s or 1,000 baud.
Baud
Measure for the transmission speed for data: 1 baud = 1 bit/s. Named after the French engineer Jean Marie Baudot (1845—1903). data rate .
HFD fluids
however. Chlorinated hydrocarbons (HFD S). Only used in closed systems within the coal industry for reasons of environmental protection. Mixtures of HFD R and HFD S. Other compositions (HFD U). Common to [...] All HFD fluids is the lack of compatibility with most materials for seals and a high density of 1.15 to 1.4 g/cm3 (intake characteristic!), which complicates any subsequent adjustment.
