According to different automatic control system, the user can select the V4, V6, V8, V10 the four-level intelligence.

V4 is world's first current step-up menu prompts; it may be adjusted without manual operator or built-in LCD

V6 three key parameters intelligent technology can complete work parameter settings and configuration function

V8 can do remote control and on site parameter setting and configuration function through HART communicate operator.

V10 can realize HART communication and button configuration function.

Users can choose three different sensors according to application to improve accuracy and reliability. The silicon piezoresistive sensors are high accuracy and low price. It is suitable to measure gauge pressure and absolute pressure.

Differential capacitance sensor: It uses f the most mature technology in the differential pressure measurement. It can measure low differential pressure in very high static pressure.

Dry-type ceramic capacitors are suitable for low pressure and negative pressure application. It can be used to strong corrosion and wear occasions.
