QYB102 Explosion-Proof Pressure Transmitter
Couldn't load pickup availability
The QYB102 adopts a 2088 industrial explosion-proof housing and uses a high-performance, high-stability piezoresistive pressure sensor as its core measuring element. The pressure signal is processed through a dedicated digital circuit and converted into standard output signals. The product has undergone rigorous long-term aging and stability screening, ensuring reliable performance even in harsh outdoor environments. With special terminal wiring and an integrated LED/LCD, it is easy to install, calibrate, and maintain.
This transmitter is ideal for fluid pressure measurement in industries such as petroleum, water conservancy, chemicals, metallurgy, power generation, environmental protection, and more. It is compatible with gases, liquids, and vapors, and performs reliably under corrosive and all-weather conditions.
Applications:
Petroleum and petrochemical industries
Water conservancy and treatment systems
Chemical processing and metallurgy
Electric power and the light industry
Scientific research and environmental monitoring
Outdoor and corrosive environments require explosion-proof solutions
