The sensor features a highly integrated, all-in-one design and is digitally temperature-compensated and non-linearity-corrected before leaving the factory, delivering high-accuracy digital pressure and temperature output.

It supports an extremely wide supply range, operating at voltages as low as 3.2 V, and can work directly with standard 3.3 V embedded systems. It can switch between low-power and normal-power operating modes, and can be networked as an RS485 slave, an I²C slave, or an SPI master/slave device.

Pressure ranges cover all ratings up to 100 MPa, in both gauge and absolute pressure types. The mechanical structure uses the industry-standard 19 mm (φ19 mm) diameter and is made of 316L stainless steel, meeting the requirements of most application environments.

As a smart pressure sensor with multiple digital interfaces, this product meets your varied requirements for digital sensing.

Note

1:​Acquiring pressure readings simultaneously over I²C/SPI and RS485 may affect the response speed. It is nevertheless recommended to keep the RS485 connection points in place, so that full-function calibration and configuration of the digital sensor remain possible in the future.

2:​If the digital sensor is used as a standalone product in an RS485 application, EMC protection components should be provided in the circuit to improve its immunity to electromagnetic disturbances such as electrostatic discharge (ESD), electrical fast transients (EFT/burst), and surges.
