SMP31 15-100 psi
Pressure Medium: Air/Gas
Sensor Type: Absolute
Supply Voltage: Under 5V, 5V
Output Signal: Millivolt
Pressure Range: 3-300 psi
Kind: Board Level

Using a high quality silicon MEMs pressure sensor as the sensing element, the SMP31 uses a vent hold for the pressure interface, resulting in a low profile. The aim of the SMP31 is to allow customers to integrate an absolute pressure sensor into their systems at costs close to that of bare pressure die. 

The SMP31 Series can be specified with pressure ranges from 15-100 psi. For a compensated and amplified pressure sensor, please take a look at our SMP31A.
