Transmitter 420 Ma 4-20 400 Bar 3051 Vacuum Pressure Sensor
Description 3051 Intelligent Capacitive Differential Pressure transducer
The 3051 intelligent pressure transmitter adopts advanced sensor
technology and self-developed high-performance digital circuit,
which is the new one of our company.
Generation of intelligent pressure transmitters. In principle, a dedicated digital processing chip is used to perform temperature and static pressure using digital compensation techniques.
Compensation to improve measurement accuracy while reducing temperature effects. The sensor that breaks through the traditional design concept is integrated with the dedicated chip circuit.
The transmitter has the characteristics of high precision, small size, light weight, convenient adjustment, high reliability and long-term stability.
EST3051 intelligent pressure transmitter has complete specifications, easy installation and use, safety and explosion protection, and can be widely used in petrochemical and electric power.
In the industries of force, metallurgy, pharmaceutical, food processing, etc., the products conform to the national "IEC" standards.
