Brief Introduction:
With our many years of successful experience on developing metal capactive smart pressure transmitter, based on HK-H100A thick film integrated circuit technology, we developed the new generation CDS-3151M series smart transmitter. CDS-3151M smart transmitter is made up of integrated sensor, connection board and LCD. The integrated sensor applies metal capactive pressure sensor with high accuracy, good long-term stability, and stron capability on overload protection. It embedded all the required core circuit into the sensor and encapsulated, which achieves sensor as transmitter. Only with external 24V power supply, it could be made into a HART smart transmitter. This technical innovation is a new approach in domestic industrial control & instrument industry, and it has also made great contribution to the development of China industrial control industry.

Main Features:
Achieve real electric isolation, thus eliminate grounding influence
Enhanced anti-jamming design, thus excellent filed anti-jamming performance
With our original design to embed all the required core circuit into the sensor and encapsulated, thus more reliable
Minished temperature drift: make uniform temperature compensation of PCB and sensor under the same temperature environment, thus better compensation effect and minished temperature drift
Strong field configuration: set zero, set span, switch display, set unit, set URL & LRL, set damping, as well as ZERO setting
High brightness backlight LCD, thus easy to read in darkness; LCD 360?rotatable freely, thus easy to watch in the field
Adjust zero and span without interference
Sensor embedded with non-losable memory
Optional process diaphragm material and explosion-proof housing construction
