Introduction of differential diffused silicon pressure sensor:
HT20V is a differential pressure sensoris a differential pressure sensitive device isolated by stainless
steel double corrugated diaphragm. Precise measurements are
achieved by isolating the diaphragm and filling the silicone oil to
the silicon pressure sensitive element. The sensor adopts the
international advanced silicon pressure chip with high stability
and high precision, and adopts the sintered base designed by stress
optimization. The production process of the sensor includes: patch,
gold wire bonding, film welding, high vacuum oil injection,
pressure circulation stress relief, high temperature aging,
temperature compensation, etc. The shape, size and sealing method
of the general products are consistent with the international
mainstream products of the same kind, and the interchangeability is
good. They are widely used for differential pressure and level
measurement in 316L stainless steel compatible media.

|
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.
