Operating conditions
Temperature Temperature Temperature Temperature
Process temperature Refer to technical data for the measuring sensor.
Ambient temperature Depending on the version and combination of outputs.
It is a good idea to protect the converter from external heat sources such as direct
sunlight as higher temperatures reduce the life cycle of all electronic components.
-40…+65°C / -40…+149°F
Ambient temperatures below -25°C / -13°F, may affect the readability of the display.
Storage temperature -50…+70°C / -58…+158°F

Physical condition Conductive, liquid media
Solid content (volume) Can be used up to ≤ 70% for OPTIFLUX and TIDALFLUX measuring sensors
The greater the solid content, the less accurate the measurements!
Gas content (volume) Can be used up to ≤ 5% for OPTIFLUX and TIDALFLUX measuring sensors
The greater the gas content, the less accurate the measurements!
