Siemens 590-505 : Air Differential Pressure Sensor, +/- 0.25-in WC, 0-10VDC, 1% Accuracy, Panel Mount
The 590 Series Differential Pressure Sensors obtain differential or gauge (static) pressures and convert this pressure difference to a proportional electrical output. Static accuracy is ±1% full scale in normal ambient temperature environments.
Features
- 10 PSI proof pressure on all ranges
- 24 Vac excitation
- 0 to 10 Vdc analog input is compatible with all energy management systems
- Fully protected against reverse wiring
- 1% accuracy improves variable air volume system performance
- Optional accuracies as high as 0.25% FS
