In the field of industrial automation, the MIK-P300Z pressure transmitter has become a cost-effective choice thanks to the outstanding performance of its diffused silicon Hirschmann sensor. As a professional manufacturer, Xi'an Shenghongchuang Instrument Co., Ltd. provides you with an analysis of the price and quality advantages of the SIN-P300Z, MIK-P300 and other series products, helping technical evaluators make informed decisions.

Technical advantages of the diffused silicon Hirschmann sensor

As the core component of a pressure transmitter, the performance of the diffused silicon Hirschmann sensor directly determines the measurement accuracy and stability of the equipment. The MIK-P300Z series uses imported German diffused silicon chips manufactured through advanced MEMS processes, featuring low temperature drift, good long-term stability, and strong overload resistance. Compared with traditional ceramic capacitive sensors, diffused silicon sensors offer better cost-performance advantages within the accuracy range of 0.1%~0.5%FS, and are particularly suitable for industries with stringent safety requirements such as petrochemicals and power energy.

Comparative analysis of mainstream models

Technical evaluators often face a choice between the SIN-P300Z and MIK-P300 series during model selection. Comparative test data show that the SIN-P300Z maintains an accuracy of ±0.2% within the operating temperature range of -40℃~125℃, while the MIK-P300Z reduces temperature impact to ±0.15% through improved packaging technology. In terms of price, due to the increase in localization rate, the MIK-P300Z is 30%~40% lower than imported products of the same specification, while its key performance indicators have already met the requirements of the IEC 60770 international standard. It is worth noting that the domestic weighing sensor PPM231-TY02 column-type tension sensor for batching hoppers and aggregate scales also adopts a similar technical route, achieving import substitution in the field of batching and weighing.

Procurement and selection guide

When selecting a pressure transmitter, the following parameters should be considered: 1) Media compatibility——the 316L stainless steel diaphragm can handle most corrosive media; 2) Long-term stability——it is recommended to select products with annual drift ＜0.1%; 3) Explosion-proof certification——chemical industry scenarios must meet ATEX or IECEx standards. The engineering team of Xi'an Shenghongchuang recommends that for conventional applications such as water treatment and HVAC, the MIK-P300Z is fully sufficient; while in extreme environments such as nuclear power stations and aerospace, the enhanced version of the SIN-P300Z is recommended.

Industry application cases

In a large thermal power plant project in Shaanxi, we configured 48 MIK-P300Z pressure transmitters for the boiler feedwater system. After three years of continuous operation monitoring, all equipment maintained Class 0.15 accuracy, completely replacing the original imported products. Similarly, in a municipal water supply pipeline network monitoring system, the NS-K series using diffused silicon technology achieved a water head measurement accuracy of ±0.5m, helping the customer save 30% in procurement costs. These practices have verified the reliability of high-end domestic sensors.
