SMT-900 Smart Electro Pneumatic Positioner
1. Quick and simple mobile phone settings;
2. Protection level 1P66;
3. A filter element is installed at the air source input end of the product to filter the air source and protect the internal piezoelectric valve;
4. Adopt an external exhaust design to cut off the air source from entering the body to prevent corrosion of the circuit board;
5. The gas consumption is close to zero in the short term, which can effectively save energy.

Product Description
This smart valve positioner is a two-wire instrument based on piezoelectric valve technology. It receives a 4~20mA current control signal and accurately controls the valve opening through built-in high-performance processing. It can automatically adjust with one click. It uses fuzzy PID mode control internally, and supports 4~20mA valve opening transmission function.
