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.
