Product Details

Pressure Transmitter used in petroleum industry (Capacitive Differential Pressure Transmitter)

Description :

Pressure or differential pressure will cause changing of capacitance value, analog signal convert to digital signal via AD and then being transfered to microprocessor, processed by microprocessor then convertted to 4~20mA analog electricity signal via DA 

Features :

Super performance, use to measure pressure, differential pressure,liquid level, rate of flow.
Accuracy: ±0.075%~±0.1%F.S
Stability: ±0.25%
Standard 4~20mA,RS-485 communication interface
Support upgrade of basic scene control technique

Application
Compatible with 316LSS,noncorrosive liquids.   
Shipping and aviation industry.
Hydraulic pressure and pneumatic control system
Apply in Petroleum industry, chemical industry, electric power, metallurgy, hydrology etc process control.
