Company Introduction                                        

Yantai dongrun Instrument Co., Ltd. was founded in 1998, specializes in manufacturing online water quality analysis equipment, material level meters, pressure gauges, flow meters, special temperature gauges and laboratory analysis equipment. Our company cooperate with the Chinese Academy of Sciences to build a water analysis laboratory, and the main products are TOC analyzer, ammonia analyzer, fluorescence oxygen analyzer, etc. We have passed the ISO9001 certification and has a professional R & D team, providing technical support to meet customer demand, particularly in the anti-corrosion, our company has a unique technology to meet different conditions of corrosion requirements.

 Product Introduction                                     

PMD-99A pressure transmitter can be divided into smart and ordinary in two forms.It adopts the world's most advanced ceramic capacitors sensor technology , thick film electronic technology, measurement without mediation liquid technology, SMT technology and HART communication technology.It has a unique structure, small temperature drift, high stability, strong resistance to overload ability, wide application range, easy installation and maintenance, etc.It can be widely used in metallurgy, petroleum, chemical, machinery, dye, pesticide industry, environment protection, etc.

Resistance to overload and impact resistant capability is strong, the instantaneous overload can attain 100 times range.

Feature

High Stability, better than 0.1%FS per year, several times higher than the other pressure transmitter.
Temperature drift is small,due to canceling the pressure measuring element of mediation liquid, and sensor is not only a high measuring accuracy, and is little affected by temperature gradient

Wider practicability, PMD product has a variety of process connections, and can adapt to industrial measurement in various places

Easy installation and maintenance, because the product has unique, simple and reasonable structure, and small volume, light weight, no need bracket, can be directly installed on the tank and piping.
