血压计传感器
DESCRIPTION
The US933A Series incorporates a piezoresistive pressure sensor and signal conditioning ASIC in 6-pin DIL plastic housing for easy through board assembling.It provides low cost way to use temperature compensated and span calibrated pressure transducer for high volume application at affordable cost.
Pressure ranges from 5 to 100 psig. Ratiometric output at 5V excitation is 0.5 to 4.5 V. Custom output can be ordered upon request. Pressure connection can be done through Tygon tube on the pressure port.
