Product Description

HT SENSOR HT24 Flush Diaphragm silicon Pressure Sensor with a Highly Stable Diffused Silicon Chip

HT24 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* 1.51/2NPT 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.

Ordering tips
  • 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.
