The 112CP series combined pressure/temperature sensor delivers the benefit of both pressure and in-stream temperature sensing in a single, robust integrated package.
The pressure transducer is a 0–5 Vdc output design that requires no end–user amplification. Similar to other TI pressure transducers, the voltage output is ratiometric to supply voltage. With a data conversion circuit referenced to supply voltage, accuracy can be maintained regardless of supply voltage variation. In addition, the circuit design includes linearity compensation, providing improved accuracy performance.
Features & Benefits
l Both pressure and temperature measurement in one package.
l Fast In-stream temperature measurement.
