HT19F Absolute and Gage ±0.15% Pressure Non-Linearity Pressure Sensor
HT19F Absolute and Gage pressure ±0.15% Pressure Non-Linearity Pressure sensor
19mm Silicon Piezoresistive Pressure Sensor
Product Introduction
The HT19F is a silicon piezoresistive pressure sensor featuring a highly stable diffused silicon element core. It accurately measures liquid and gas pressure by transmitting the tested medium's pressure to the silicon diaphragm through an isolation diaphragm and silicon oil. This versatile sensor is extensively used in air compressors and refrigeration systems.
Product Features
Advanced technology with 316L stainless steel housing and premium diaphragm materials including titanium and Hastelloy
Thick-film circuits for precise temperature compensation and zero-point correction
Outstanding reliability, repeatability, and stability
Applications
Measurement of non-corrosive gas and liquid pressure with 316L stainless steel compatibility
Industrial process sites including petroleum, chemical, metallurgy, power, and hydrology
Marine and aviation industries
Hydraulic and pneumatic control systems
Process control applications
Electrical Performance
Power Supply: ≤2mA DC (Typical 1.5mA DC)
Input Impedance: 3KΩ~6KΩ
Output Impedance: 2.5KΩ~6KΩ

Ensure proper fit between core size and transmitter housing for required airtightness during assembly
Maintain vertical alignment and apply even pressure during housing assembly to avoid damaging the compensation plate
Provide special instructions when ordering if the measured medium is incompatible with core diaphragm and housing material (316L)
Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage from deformation or piercing
Keep gauge pressure core pressure port open to atmosphere and prevent entry of water, water vapor, or corrosive media
Refer to the label on the actual core for any pin lead changes
