Pressure Sensor Series YCQB

Pressure Sensors Pressure Sensor Series YCQB

Pressure sensors are widely used in Air Conditioning, Refrigeration and Heat Pump system. Using a 5 V excitation input these sensors provide a 0.5-3.5 V or 0.5-4.5 V ratiometric signal output proportional to the pressure of the medium. This device requires no end user amplification.Pressure sensors permit to control and guarantee the system working under safe and stability condition.
