Detailed 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.

Ordering tips

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