Figure 4. Output versus Absolute Pressure

TRANSFER FUNCTION:

Vout = Vs* (.009*P–.095) ± Error

VS = 5.0 Vdc

TEMP = 0 to 85

°C

Figure 4 shows the sensor output signal relative to pres-

sure input. Typical minimum and maximum output curves

are shown for operation over 0 to 85

°C temperature range.

The output will saturate outside of the rated pressure range.

A fluorosilicone gel isolates the die surface and wire

bonds from the environment, while allowing the pressure

signal to be transmitted to the silicon diaphragm. The

MPXA6115A/MPXH6115A series pressure sensor operating

characteristics, internal reliability and qualification tests are

based on use of dry air as the pressure media. Media other

than dry air may have adverse effects on sensor perfor-

mance and long–term reliability. Contact the factory for

information regarding media compatibility in your application.
