Description
The WPAH01 ceramic pressure sensor is a ceramic piezoresistive pressure sensor manufactured using a refined ceramic substrate and a thick-film process. Its dimensions are Φ18mm * 6.35mm. Ceramics are recognized as highly elastic, corrosion-resistant, wear-resistant, and resistant to impact and vibration. The excellent thermal stability of ceramics and the high-temperature sintering process of the thick film allow the ceramic pressure sensor to operate over a temperature range of -40 to 12°C. The high elasticity and creep resistance of ceramics give the ceramic pressure sensor excellent long-term stability. Furthermore, the corrosion resistance of ceramics provides it with unique advantages in refrigeration, chemical, and environmental protection fields.
Application
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.

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, but the module will be 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 sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
