The PX139 Series has been discontinued and will no longer be available once existing stock is depleted. Please see the PXSCX as possible alternatives or contact our Pressure Engineering department.
The PX139 Series pressure transducer uses state-of-the-art micro-machined silicon pressure sensors along with stress free packaging techniques to provide highly accurate, temperature compensated pressure transducers for the most demanding applications. Designed to operate from a 5 volt DC power source the PX139 provides a calibrated 4 volt output span of 0.25 to 4.25 volts.
