*; Measurable without temperature conversion |
Temperature : 0 to 100°C
Desalination rate : 0 to 100% |
| Repeatability |
within ±0.1% of the full scale (in equivalent input) |
| Linearity |
within ±0.1% of the full scale (in equivalent input) |
| Transmission output |
2 output points,
Max. load resistance: 900Ω
4 to 20 / 0 to 20 mA DC : input / output isolated type
- Transmission output range : Freely selectable within the measurement range. However, repeatability and linearity will remain accurate to the
separately set measuring range.
(Negative terminals of each transmission output channel are connected
inside and thus have the same electric potential.) |
