NOTICE
The insulation can also be thicker than the recommended insulation thickness.
Prerequisite:
‣
The temperature at the lower end of the transmitter housing does not exceed 80 °C (176 °F)
‣
Ensure that convection takes place on a sufficiently large scale at the transmitter neck.
‣
Ensure that a sufficiently large area of the housing support remains exposed. The uncovered part
serves as a radiator and protects the electronics from overheating and excessive cooling.
Heating
Some fluids require suitable measures to avoid loss of heat at the sensor.
Heating options
• Electrical heating, e.g. with electric band heaters
• Via pipes carrying hot water or steam
• Via heating jackets
Heating jackets for the sensor can be ordered as accessories from Hauser (→ 73).
Vibrations
The high oscillation frequency of the measuring tubes ensures that the correct operation of the
measuring system is not influenced by plant vibrations.
