Product Details
Oil Filled Diffused Sillcon Pressure Transmitter Sensor For Water
And Oil Test
19mm Silicon Piezoresistive Pressure Sensor
Introduction of Pressure Transmitter Sensor:
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
refrigerationsystems.
Product Features of Pressure Transmitter Sensor:
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 of Pressure Transmitter Sensor:
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
Electrical performance of Pressure Transmitter Sensor:
1.Power Supply: ≤2mA DC (Typical 1.5mA DC)
2.Input Impedance:3KΩ~6KΩ
3.Output Impedance:2.5KΩ~6KΩ
4.Electrical Connection:Gold-plated Kovar pins or 100mm
high-temperature wires.

Electrical connection and compensation |
|
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.
