Description
PS19C is made from high-quality silicon piezo-resistive sensor
chip. The piezo-resistive sensor chip is packaged
in a fluid-filled cylindrical cavity and isolated from measured
media by a stainless steel diaphragm and housing. The output of
PS19ACcan be configured to 10%~90%Vs ratiometric,4~20mA, I2C by
integrated the
electronics. Integrated the electronics is used for temperature
compensation, offset correction.
PS19C pressure sensor are designed for floating O-ring
seal mounting. This not only can avoid housing induced
stress,but also is easy for installation.
