Product Details

General Introduction:

Our PT-3051 pressure transmitter adopts advanced high-precision intelligent sensor elements, with high cost-effective. Using the digital capacitor circuit to replace analog signal amplifying circuit and A/D conversion circuit in conversion method. Using digital compensation technology to compensate for temperature and static pressure, improving measurement accuracy and reducing temperature drift. The product has features of long-term stability, high reliability, strong self-diagnosis, etc.


Our products have approved CE certification, which can directly replace similar products. All the products can be customized according to your requirements, we can also accept OEM.
