The choice of cleaning materials used to clean the probe will depend on the
nature of the process material residue on the probe. Choose an appropriate
solvent and clean well.
Do NOT apply significant lateral force to the probe tip or use sharp objects to
scrape process material off the transducer probe.
6.3 Checking the Transducer Calibration
While the transducer is removed from the installation location, the transducer
calibration may be checked. In order to check the transducer calibration, a series
of liquids of known viscosity (with known density at a known temperature) is
required. This may be a Newtonian Viscosity Standard or other material of known
viscosity and density at a known temperature.
Galvanic Applied Sciences Inc. recommends the use of Cannon Viscosity
Standards, available directly from Galvanic. Should the viscosity measurement
range of the transducer be sufficiently low, distilled water may be used. The
viscosity of distilled water is about 0.9 cP at 25 °C, with a density of 1 g/cm3.
The manufacturer of the viscosity standard provides both the viscosity and
density values for the standard at a known temperature, as shown in Figure 6.4.
It is critical to ensure the viscosity standards and transducer are at a known and
stable temperature
–
preferably the temperature listed on the label of the
standard. If the test environment is not well controlled and at a temperature
corresponding to the known viscosity of the standard, comparison to the original
factory calibration is possible but should not be expected to be identical.
