Silicon Diaphragm Pressure Sensor Description
Based on piezo-resistive silicon technology, PT401 differential
pressure transmitter uses silicon differential pressure sensors
with stainless steel isolated diaphragm as measuring elements. Made
of 316L stainless steel and designed of rigid and robust
construction, PT401 differential pressure transmitter has a feature
of that zero point and full range can be adjusted. It is suitable
for application in harsh environment and measurement with corrosive
pressure media.
This product has widely been used for measurement of differential
pressure of pipeline fluids in petroleum industry, chemical
industry, electric power hydrology etc.
