Product Description Hengtong Absolute Gauge Piezoresistive Air
Gas Pressure Sensor with Welded FittingsHT19 Silicon Piezoresistive
Pressure SensorIntroduction: HT19 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
refrigeration systemsProduct 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 stabilityApplications:1.Suitable
for measuring non-corrosive gas and liquid pressure with
316L stainless steel compatibility2.Applied in various
industrial process sites, including petroleum, chemical,
metallurgy, power, and hydrology 3.Used in marine and
aviation industries4.Suitable for hydraulic and pneumatic control
systems5.Utilized in process control applicationsElectrical

Selection ExamplesOrdering tips1. Pay attention to the
fit between the core size and the transmitter housing during
assembly to achieve the required airtightness2. 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. Q&A 1.Q: What
