SHANGHAI CHENZHU INSTRUMENT CO., LTD. is a very established provider that specialises in automation safety. We have over 24 years of experience in the design and manufacture of intrinsic barrier, signal conditioner, surge protection device, safety relay, power transmitter and temperature transmitter. Our products and solutions cover many areas--from process automation safety to factory automation.

Safety is a primary focus in the petrochemical industry wherein different process steps, such as cracking, condensation, or distillation, the respective intermediate or finished products are manufactured under defined pressure and temperature conditions.

As an instrument maintainer of instrument control systems, CHENZHU's intrinsic isolated barrier receives and processes signals from hazardous areas and transmits them to safe areas or hazardous areas after processing safety signals. The barrier is a typical product of the safety automation system.

As shown in the picture, the construction and working of the offshore oil platform are huge and onerous. Frankly, though the barrier is small, it plays an important role in the whole system.
