316L Stainless Steel Compatibility Flush Diaphragm Silicon Pressure
SensorHT24 Silicon Piezoresistive Pressure Sensor
Introduction of flush diaphragm silicon pressure sensor: HT24 is a flush diaphragm pressure sensor with a highly stable
diffused silicon chip. The sensitive chip does not directly contact
the measured medium. Pressure is transferred to the sensitive chip
through a stainless steel diaphragm and sealing silicone oil. This
product is a flat diaphragm structure with thread, G1/2 M20*
1.5 1/2NPT is the most commonly used thread. Easy to clean, high
reliability. Suitable for food, health and other industries.
Product Features of flush diaphragm silicon pressure sensor:
- Utilizing advanced technology and 316L stainless steel housing,
along with materials such as titanium and Hastelloy for the diaphragm.
- Employing thick-film circuits for temperature compensation and
zero-point correction.
- outstanding reliability, repeatability, and stability.
- Flush diaphragm structure, which makes it easy to clean.
Applications of flush diaphragm silicon pressure sensor:- Suitable for measuring non-corrosive gas and liquid pressure with
316L stainless steel compatibility.
- Food and beverage industry.
- Industrial process control.
- Pharmaceutical industry.
Electrical performance of flush diaphragm silicon pressure sensor:- Power Supply: ≤2mA DC (Typical 1.5mA DC)
- Input Impedance : 2.5KΩ~6KΩ
- Output Impedance: 2.5KΩ~6KΩ
- Electrical Connection: Gold-plated Kovar pins or 100mm
high-temperature wires.

- 1. During assembly, attention should be paid to the coordination
between the core size and the transmitter housing to achieve the
required tightness.
- 2. In the process of the shell assembly, to ensure that the
vertical alignment, and uniform pressure, to avoid the stuck or
damage compensation board.
- 3. If the tested medium is not compatible with the core diaphragm
and housing material (316L), special instructions should be
provided when placing the order.
- 4. Avoid pressing the sensor diaphragm by hand or sharp objects, so
as not to damage the core due to deformation or puncture of the
diaphragm.
- 5. Keep the pressure of gage pressure core mouth open to
atmosphere, prevent water, steam, or corrosive medium into the
negative pressure gauge pressure core chamber.6. If there are any
change pin, please according to the label on the actual conductor
for reference.
