HT26V Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT26V silicon pressure sensor is a kind of piezoresistive type, its
core is the spread of the highly stable silicon crystal
components.The pressure difference of the measured medium is
transferred to the silicon diaphragm through a 316L isolation
diaphragm and sealed silicone oil.Custom structures are made from a
conventional diameter of 19mm and are highly customized, with
stainless steel parts available as low as 7mm.5-10V constant
voltage power supply, regular output.HT26V pressure sensor is
equipped with o-rings, used for pressure seal, convenient
installation.

1. In the assembly, attention should be paid to the coordination of
the core size and the transmitter housing to achieve the necessary
tightness.
2. During the assembly of the shell, ensure that it is vertically
aligned and apply pressure evenly to avoid getting stuck or
damaging the compensation plate.
3. If the medium under test is not compatible with the core
diaphragm and housing material (316L), special instructions should
be provided when placing the order.
4. Avoid pressing the sensor diaphragm with your hands or sharp
objects to avoid deformation or puncture of the diaphragm and
damage to the core.
5. Keep the pressure port of the gauge pressure core open to the
atmosphere to prevent water, water vapor or corrosive media into
the negative pressure chamber of the gauge pressure core.
6. If there is any change in the pin, please refer to the label you
actually carry.
7. Customizable, please contact the business manager to negotiate.
