Product Description

Product Description
High Accuracy 0.25% Low Cost Water Oil Hydraulic Pressure Sensor    
High stable OEM sensor is the piezoresistive pressure  sensor with isolated construction and precise compensation. It

uses high stable silicon die, stainless steel 316L housing with  diameter Ф19mm. Wider temperature compensation and zero
correction are calibrated by laser trimming technics. The measured pressure is transmitted onto silicon die through 316L diaphragm

and inner media, to transform the pressure to electric signal. It can be filled with Fluorinated Oil. Because of its good biological

inertness, it can dissolve a large amount of breathing gas, and can be quickly discharged from the human body. It is more suitable for

the pressure measurement of the oxygen in medical applications. XYT19 pressure sensor is inspected and screened on automatic .

production line, testing and checking time after time strictly. It is widely used for various pressure measurement fields.
