Professional manufacturer of sensors
G1/2 Brass Hall Effect Flow Sensor – NPN Pulse | -10~100°C | 1.75MPa Heavy Duty
Pain & Scenario: Standard plastic sensors warp and drop signals in extreme thermal cycling or high-pressure chillers, causing costly system failures and inaccurate readings.
Solution: The SAIER G1/2 Brass HVAC chiller flow sensor eliminates these risks. Forged from heavy-duty 57 Brass, it withstands 1.75MPa hydraulic shocks and survives -10°C freezing to 100°C boiling loops. To guarantee absolute signal fidelity, the sleeved 350mm harness features upgraded wire cores, completely preventing oxidation and ensuring flawless NPN pulse transmission to your controller.
Case & Algorithm: Commercial heat pump manufacturers use this sensor to achieve zero field-failure rates. Stop relying on estimated data and optimize your PLC using our precise installation-specific calibration algorithms:
Horizontal: $F = [11Q – 5] ± 10%
Vertical: $F = [11Q – 2] ± 10%
