HT26V Piezoresistive silicon Pressure Sensor
Introduction of silicon pressure sensor core:
HT26V is a piezoresistive silicon pressure sensor core. It uses the
piezoresistive effect of diffused silicon to measure the pressure
of liquids and gases. Constant voltage power supply output is
relatively standard, lower than normal HT19 height, suitable for
special case assembly.
This product is a customized product, can be customized constant
voltage power supply or constant current power supply, the height
can be customized according to the field needs, and finally fully
applicable to customer requirements.

1. Pay attention to the fit between the core size and the
transmitter housing during assembly to achieve the
required airtightness
2. During the assembly of the housing, ensure it is aligned
vertically and apply even pressure to avoid jamming or damaging the
compensation plate.
3. If the measured medium is not compatible with the core diaphragm
and the housing material (316L), special instructions should be
provided when placing the order.
4. Avoid pressing the sensor diaphragm with hands or sharp objects
to prevent damage to the core due to diaphragm deformation or
piercing.
5. Keep the pressure port of the gauge pressure core open to the
atmosphere and prevent the entry of water, water vapor, or
corrosive media into the core negative pressure chamber.
6. If there are any changes to the pin leads, follow the label on
the actual core for reference.
