100mbar 19mm Compact Conventional Pressure Sensor Core
HT19 Silicon Piezoresistive Pressure Sensor Introduction: HT19 is a silicon piezoresistive pressure sensor featuring a highly stable diffused silicon sensing element. It accurately measures the pressure of liquids and gases by transmitting medium pressure to the silicon diaphragm through an isolation diaphragm and silicone oil. With its compact size, high accuracy, and cost-effectiveness, this versatile sensor is widely used in applications such as air compressors and refrigeration systems.
Product 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

1. Core-to-Housing Fit: Ensure the core size is compatible with the transmitter housing prior to assembly to achieve the required level of airtightness.
2. Housing Assembly: During assembly, maintain vertical alignment of the housing and apply even, controlled pressure to prevent jamming or damage to the compensation plate.
3. Media Compatibility: Verify that the measured medium is chemically compatible with the core diaphragm and housing material (316L stainless steel). If compatibility is not guaranteed, you must provide special instructions at the time of order placement.
4. Diaphragm Protection: Never touch the sensor diaphragm with fingers or sharp objects. The diaphragm is extremely sensitive and can be permanently damaged by deformation or piercing.
5. Gauge Pressure Reference: For gauge pressure cores, the pressure port must remain open to atmospheric pressure. Take care to prevent moisture, water vapor, or any corrosive media from entering the negative pressure chamber.
6. Electrical Connections: Always refer to the wiring label attached to the actual core for pin lead connections. Do not rely on external documentation if the pin configuration has been modified.
