Square-root extracted pressure transducer.
Measuring range 0 - 100 Pa to 0 - 20 kPa.
Based on a square root-extracted output characteristic, this differential-pressure transducer is particularly suitable for measuring the volumetric flow rate, e.g. in air-conditioning units, in fans and ventilation ducts. The volumetric flow rate/flow velocity can be read off directly on-site via an optional display.
The 3 or 4-figure LC display is available as an option. In addition to Pa and kPa, it can also display mmWs, inch H2O m3/h, m/s etc.
An optional time constant of up to 5 s means the device can also be used under fluctuating pressure conditions and generates a stabilised output signal.
Measuring ranges:
from 0 - 100 Pa to 0 - 20 kPa
Linearity: ± 1 %
Output signals: 0 - 10 V
0 - 20 mA, 4 - 20 mA
Supply voltages:
230 VAC, 115 VAC,24 VDC, 24 VAC
Time constants: 1,2,5 s optional
Medium: air, all non-aggressive gases.
Can also be calibrated in other units of measurement, e.g. mbar, mmWs, psi, m3/h, m/s etc.
