Acuity Packaged Sensor

Suitable for a wide range of uses, it is particularly designed for low-pressure differential sensing in such applications as HVAC, air-flow, and a variety of industrial pressure and flow applications.

The AC401X series packaged pressure die is a single in-line package (SIP) with 4 pins and differential pressure ports. It is meant for applications where a simple package is needed but where additional signal processing will likely be used to connect the sensor to other electronics.

The package houses an Acuity low pressure sensor. For pressures 20 mBar and higher, an AC3030 die is used in the AC4010. For the 10 mBar range, an AC3050 die is used. Two versions of the 10 mBar part are available. The AC4010-010 offers the same linearity as the AC3050 while the AC4015-010 offers the improved linearity of the AC3055, typically used for passive compensation schemes, but at a slight decrease in sensitivity.
