Introduction：

HPT301pressure sensors consist of a ceramic base plate and a flush diaphragm and work with the piezoresistive principle The Wheatstone bridge is screen printed on one side of the flush ceramic diaphragm which is glued to the sensor’s body conversely. The bridge faces the inside where a cavity is made and the Diaphragm’s opposite side can therefore be exposed directly to the medium to be measured. The Al 2O3 ceramic has excellent chemical resistance, so no additional protection is normally required.

HPT301 sensors are thermally compensated by laser-adjustable PTC resistors and the use of ceramic ensures a high linearity across the entire range of measurement, reducing effects of hysteresis to a minimum.
