Product Description

WD19 Piezoresistive Pressure Sensor
       D10 series is a 14-bits digital output pressure sensor, supporting I2C interface protocol. The external pressure is passed to sensitive elements through 316L stainless steel diaphram and internal silicon oil. Thus D10 sensors can be used to measure all pressure media compatible with 316L stainless steel.
       The series sensor realizes pressure and temperature calibration and compensation via a specially customized integrated circuit. It outputs 10%-90% digital signal as well as digital output of temperature signal.
 

Features - Pressure Sensor:

1.  High stability and high accuracy
2.  Low cost OEM
3.  Suited for pressure range: 0-40Kpa-7Mpa
4.  Wide temperature compensation range: total error <1%
5.  Measurable of corrosive media ( media compatible with 316L)
6.  Standard mounting size
7.  Communication: I2C or SPI
