瑞典TA-CBI测量设备
Technical description
TA-CBI is a computer programmed balancing instrument. It c***ists 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 connecti***.
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 &plu***n;1% of displayed value or&plu***n;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 le***e water in the sensor when there is a risk of
freezing.
