Product Description
19mm Mini 4-20mA Output Silicon Pressure Sensor For OEM Transmitter
HT19-4-20 Pressure Sensor
Introduction of silicon pressure sensor:
HT19-4-20 Silicon Piezoresistive Pressure Sensor
The HT19-4-20 is a high-stability piezoresistive pressure sensor featuring a precision diffused silicon sensing element. It accurately measures liquid and gas pressure by transmitting force through a silicon diaphragm and isolating the medium via a silicone oil-filled isolation diaphragm.
Equipped with a sophisticated amplifier circuit, it delivers a standardized 0.5–4.5VDC or 4–20mA output for seamless integration. Its robust design and versatility make it ideal for applications such as air compressors, refrigeration systems, and HVAC equipment.
Key Features:
- High long-term stability
- Media isolation for corrosive or sensitive environments
- Industry-standard output signals
- Reliable performance in demanding industrial applications
Applications of silicon pressure sensor:
- Suitable for measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility.
- Applied in various industrial process sites, including petroleum, chemical, metallurgy, power, and hydrology
- Used in marine and aviation industries.
- Suitable for hydraulic and pneumatic control systems
- Utilized in process control applications.

HT19-4-20 Pressure Sensor Assembly & Handling Guidelines
-
Core-to-Housing Fit
-
Ensure proper alignment between the core and transmitter housing to maintain required airtightness.
-
-
Housing Assembly
-
Keep the housing vertically aligned during assembly.
-
Apply uniform pressure to prevent jamming or damage to the compensation plate.
-
-
Material Compatibility
-
If the measured medium is incompatible with the 316L housing or core diaphragm, specify this when ordering for customized solutions.
-
-
Diaphragm Protection
-
Avoid contact with hands or sharp objects to prevent deformation or puncture of the sensing diaphragm.
-
-
Gauge Pressure Core Venting
-
Keep the pressure port open to the atmosphere.
-
Prevent moisture, steam, or corrosive media from entering the negative pressure chamber.
-
-
Pin Lead Modifications
-
Refer to the actual core label for correct wiring if pin leads are altered.
