Aplisens APRE-2000 PD Smart Differential Pressure Transmitter is applicable to the measurement of differential pressure of gases, vapors and liquids. The active element is a piezoresistant silicon sensor separated from the medium by separating diaphragms and a specially selected type of manometric fluid.
The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250, 320 or 413 bar. Electronics in the casing with a degree of protection IP65, IP66.
Aplisens APRE-2000 PD Metrological Parameters
- Accuracy: ≤±0,1% of calibrated range
- Long term stability (for the nominal measuring range):
- ≤ accuracy for 3 years
- ≤ 2 x accuracy for 5 years
- HS version: ≤ accuracy for 6 years
- or ≤ 2 x accuracy for 10 years
- Thermal error
- < ±0,08% (FSO) / 10°C
- max. ±0,3% (FSO) in the whole compensation range
- Thermal compensation range: -25…80°C
- Zero shift error for static pressure
- 0,01% (FSO) / 10 bar for ranges no. 3, 4, 5, 6, 7, 9
- 0,03% (FSO) / 10 bar for range no. 8
- 0,06% (FSO) / 10 bar for ranges no. 1, 2
- 0,01% (FSO) / 10 bar for ranges no. 2, 8 in HS version
- 0,02% (FSO) / 10 bar for range no. 10
Zeroing the transmitter in conditions of static pressure can eliminate this error.
- Response time: 16…230ms (programmable)
- Additional electronic damping: 0…60 s
- Error due to supply voltage changes: 0,002% (FSO) / V
