Technical description

TA-CBI is a computer programmed balancing instrument. It consists of an electronic differential pressure gauge and a
micro computer which has been programmed with the TA
valve characteristics which makes possible a direct reading of flow and differential pressures.
The TA-CBI has two main components:
- An instrument which contains a micro computer, input touch
pad, LCD display and re-chargeable NiMh batteries.
- A sensor unit which contains a piezoresistive pressure
sensor, one measurement valve and connections.
The measurement valve has a safety function which protects
the sensor from too high differential pressures.
Measurement range:
Total pressure: max 2 500 kPa.
Differential pressure: -9 to 200 kPa.
Flow: During flow measurements the pressure range is 0.5 to200 kPa.
Temperature: -20 to 120°C

Temperature liquid medium:
-20 to 120°C
Measurement deviation:
Differential pressure: The greater of ±1% of displayed ＆#118alue or
±0.2 kPa
Flow: As for differential pressure + valve deviation.
Temperature: <0.2°C + sensor deviation.
Effective operating time:
8 to 10 h between charges depending upon application.
Ambient temperature for the instrument:
0 to 40°C （during operation）
5 to 40°C （charging）
-20* to 60°C （storage）
*） Do not leave water in the sensor when there is a risk of
freezing.
