Technical Parameter Comparison: Accuracy, Range and Stability

In industrial flow control systems, the core performance of pressure transmitters directly affects process accuracy and safety. Both SUP-P300Z and MIK-P300 use diffused silicon sensing technology, but there are significant differences in their technical parameters:

• Measurement accuracy: SUP-P300Z reaches ±0.1%FS (full scale), outperforming MIK-P300's ±0.2%FS, and is especially suitable for industries such as pharmaceuticals and semiconductors that are sensitive to slight pressure fluctuations
• Range: MIK-P300 supports ultra-high-pressure measurement from 0-100MPa, while SUP-P300Z has a maximum range of 60MPa, but offers micro-pressure range options of 0-5kPa
• Temperature compensation: Both products are equipped with full-temperature-range compensation, and SUP-P300Z has a stability error of ≤±0.5%/10℃ within the range of -40℃~125℃

According to the standard test of GB/T 17614-2015 for transmitters used in industrial process control systems, SUP-P300Z performs better in long-term drift indicators, with annual stability ≤±0.1%FS.

Application Scenario Adaptability Analysis

Different operating conditions have clearly differentiated requirements for pressure transmitters, and selection should be based on specific application scenarios:

1. Harsh environment adaptability

MIK-P300 has passed IP68 protection certification and EX d IIC T6 explosion-proof certification, making it more suitable for petrochemical, mining machinery and other environments with explosion risks or high dust levels. Its 316L stainless steel housing can resist corrosion from H2S acidic media.

2. Dynamic response requirements

SUP-P300Z has a response time of ≤1ms, and with its built-in FIR digital filtering function, it has unique advantages in scenarios with rapid pressure changes such as pulsation measurement in hydraulic systems and wind tunnel testing.

3. System integration complexity

Both products support HART/RS485 communication protocols, but SUP-P300Z additionally provides a 4-20mA+pulse output option, which can simplify the wiring structure of multi-signal acquisition systems.

Full Life Cycle Cost Evaluation

It is worth noting that the modular design of SUP-P300Z allows on-site replacement of the sensing unit, which can reduce maintenance costs by more than 60% compared with the overall replacement solution of MIK-P300.

Decision-Making Recommendations and Industry Practices

Based on Xi'an Shenghongchuang's experience in 200+ projects in the process industry, we provide the following selection guidelines:

1. Scenarios where SUP-P300Z should be prioritized:
   • Long-term stability is required (such as energy metering transfer)
   • Severe pressure fluctuations exist (such as compressor outlet monitoring)
   • Deep integration with PLC/DCS is required
2. Cases where MIK-P300 is recommended:
   • Bulk procurement projects with limited budgets
   • Corrosive media environments (such as chlor-alkali chemical industry)
   • Monitoring points for non-continuous measurement
