Note 1) Reference conditions are based on JEMIS-032.
Note 2) Refer to the 4 pages for the accuracy according to kind of detector
Flow Transmitter
- Power supply: Built-in battery or AC power adapter.
- Built-in battery : Exclusive lithium button battery (5000 mAh). Continous operation time, approx. 12 hours (without printer, backlight OFF, output current not used and at normal ambient temperature (20°C)). Recharging time, approx. 3 hours (power adapter used).Recharging temperature range : 0 to +40°C. Power consumption : Min. 3W and Max. 16W. The consumption varies depending on the used conditions.
- Power adapter : Exclusive power adapter 100V to 240V +10%/-15% AC (50/60 Hz), 90 VA or less.
- Display : TFT color graphic LCD 240 x 320 (with backlight) Neasurement value (instantaneous flow rate, integrated flow rate) and various settings are displayed. Excellent visibilty even outdoors in direct sunlight.
- Analog Output Signal : 4 to 20mA DC, one point (load resistance, 600Ω or less). Instantaneous velocity, instantaneous flow rate or heat quantity (calorie) after scaling.
- Analog Input Signal : Total 2 point inputs
