Industrial Application Value of Diffused Silicon Herschmann Sensors

In industrial fields such as petrochemicals and electric power energy, the accuracy and reliability of pressure measurement directly affect production safety and efficiency. The MIK-P300 pressure transmitter adopts the original German Herschmann diffused silicon sensor core, successfully solving the drift problem of traditional sensors under high-temperature and high-pressure working conditions through a high overall accuracy of 0.1%FS and a fast response of ≤1ms. Test data from Xi'an Shenghongchuang Instrumentation Co., Ltd. show that this series of products can still maintain long-term stability of ±0.2%FS/year at an extreme temperature of 85℃, far exceeding the requirements of the IEC 60770 international standard.

Typical Application Scenarios and Technical Breakthroughs

After a large refinery adopted the MIK-P300Z pressure transmitter in its catalytic cracking unit, it achieved real-time and precise monitoring of reactor pressure. Its 316L stainless steel isolation diaphragm and three-level lightning protection design effectively resist hydrogen sulfide corrosion and electromagnetic interference. Compared with traditional capacitive sensors, diffused silicon technology expands the measurement range to 200m water column and increases overload capacity by 150%, while the equipped LCD display module supports rapid on-site diagnostics. It is worth noting that the domestic liquid level transmitter JYB-KO-Y3 of the same series demonstrated similar performance advantages in sewage treatment projects. Its explosion-proof design complies with ATEX standards, and the IP65 protection rating ensures stable operation in harsh environments.

Comparative Analysis of Key Technical Parameters

Five Core Factors in Procurement Decision-Making

Technical evaluators should focus on the following when selecting diffused silicon Herschmann pressure sensors: 1) medium compatibility——for strong acid and alkali working conditions, Hastelloy material should be specified; 2) explosion-proof certification——the MIK-P300Z has passed NEPSI explosion-proof certification; 3) signal stability——the 4-20mA output needs to be equipped with reverse polarity protection; 4) installation convenience——multiple interface specifications such as flange/thread are provided; 5) life cycle cost——the 5-year warranty provided by Xi'an Shenghongchuang significantly reduces TCO. Actual cases show that correct model selection can reduce equipment failure rates by more than 60%.
