A: Temp.Sensor
- Linear temperature compensation based on a manually entered
temperature coefficient (see appendix A.1 on page 73) - see
frame on page 26.
Temp.Coeff.
Example
- Non-standard applications.
- Temperature compensation based on the temperature coefficient
of pure water. Source data is based on International Standard IEC
60746-3.
Also enables manual entry of a temperature coefficient (see
frame on page 26) for applications where pure water
Temp.Coeff.
contains an unknown impurity; in which case the temperature
coefficient must be calculated - see appendix A.1.1 on page 74.
- Temperature compensation based on the temperature coefficient
of pure water containing trace acids.
Examples
- Cation exchanger in-bed and outlet applications.
- Degassed cation/conductivity applications.
- Temperature compensation based on the temperature coefficient
of pure water containing trace caustic.
Example
- Inferred pH in caustic-dosed waters applications.
- Temperature compensation based on the temperature coefficient
of pure water containing trace salts.
Examples
- General monitoring applications.
- Mixed-bed exchanger applications.
- Final polisher effluent applications.
- Cation exchanger inlet applications.
- Anion exchanger in-bed and outlet applications.
- Reverse osmosis applications.
- Temperature compensation based on the temperature coefficient
of pure water containing trace ammonia.
Examples
- Ammonia-treated make-up and boiler feed water applications.
- Condenser sampling applications.
- Hot well sampling applications.
- Before-cation column applications.
- Inferred pH in ammonia-dosed waters applications.
