HT19F Pressure Sensor Cell with Temperature Compensation Level
Sensor
Pressure sensor with temperature compensation
19mm Silicon Piezoresistive Pressure SensorIntroduction:
HT19F functions as a silicon piezoresistive pressure sensor ,with a
core consisting of a highly stable diffused silicon element,.
It effectively measures the pressure of liquids and gases by transmitting the pressure of
the tested medium to the silicon diaphragm through an isolation diaphragm and
silicon oil.The sensor's versatility finds extensive use in air compressors and
refrigerationsystemsProduct Features:
1.Utilizing advanced technology and 316L stainless steel housing,
along with materials such as titanium and Hastelloy for the diaphragm
2.Employing thick-film circuits for temperature compensation and
zero-point correction
3.outstanding reliability, repeatability, and stability
Applications:
1.Suitable for measuring non-corrosive gas and liquid pressure with
316L stainless steel compatibility
2.Applied in various industrial process sites, including petroleum,
chemical, metallurgy, power, and hydrology
3.Used in marine and aviation industries
4.Suitable for hydraulic and pneumatic control systems
5.Utilized in process control applications

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.
