The PT3511 piezoresistive sensor die is designed for pressure and temperature measurements using a single chip.
When excited by either constant voltage or constant current, a PT3511 pressure sensor produces a differential millivolt output signal directly proportional to the applied pressure. With NovaSensor’s SenStable® process, PT3511 die features excellent long-term stability and repeatability (< 0.1% / year typ.). The on-chip temperature sensor powered by constant current allows for high accuracy measurement of temperature and for improvement of pressure measurement accuracy.
