WPAH01 ceramic pressure sensor adopts ceramic base, made into ceramic piezoresistance pressure sensor with thick-film technology. It’s size Φ18mm*6.35mm. Ceramic is a kind of material with high elasticity, corrosion resistance, wear resistance, resistance to impact and vibration. Ceramic’s good thermal stability and thick film high temperature sintering process make the ceramic pressure sensor’s operating temperature range up to -40 ~ 125 ℃. The ceramic's high elasticity and creep resistance make the ceramic pressure sensor have good long-term stability. Besides, the corrosion resistance character makes the sensor have unique advantages in the application such as the refrigeration, chemical and environmental protection and other fields.


  • WPAH01 ceramic pressure sensors are widely used in: process control, environmental control, hydraulic and pneumatic equipment, servo valves and transmission, smart building automation, chemical and chemical industry and medical instruments and many other fields.
  • Now, high-performance and low-cost ceramic sensor is the direction of development of pressure sensors with the trend of replacing other type sensors in Europe and the United States. In China, more and more users choose ceramic sensors instead of strain and diffusion Silicon pressure sensor.


  • Ceramic sensitive film with high overload capacity
  • Laser calibration for zero and full scale
  • Excellent corrosion resistance, wear resistance
  • Impact resistance, anti-vibration
  • High precision, good stability
  • Wide operating temperature range
  • Small size, easy to package
  • Environmental protection

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
