Performance Test Report of the MIK-P300 Pressure Transmitter Under Extreme Environments

This article provides a detailed test of the performance of the MIK-P300 pressure transmitter under extreme environments. As a high-end product in the SUP-P300Z series, this transmitter can still maintain accurate measurement under harsh operating conditions such as high temperature, low temperature, and high humidity. The test report will provide key data support for technical evaluators, helping them understand the reliability and stability of the SUP-P300 pressure transmitter.

1. Test Background and Methods

In the field of industrial automation, the stability and accuracy of pressure transmitters directly affect production safety and efficiency. As a high-end model in the SUP-P300Z series, MIK-P300 adopts advanced sensing technology and sealing processes, and is specially designed for extreme working conditions. This test aims to verify its performance under the following environmental conditions:

• High-temperature environment: -20℃至85℃ continuous operation test
• Low-temperature environment: -40℃至-20℃ cold start test
• High-humidity environment: long-term stability test under 95%RH humidity
• Vibration test: accuracy retention under 10-2000Hz random vibration environment

The test equipment uses a national primary standard pressure source with an accuracy of up to 0.05%FS, and all test data were collected by an ISO/IEC 17025 accredited laboratory.

2. High-Temperature Environment Performance Test

In an 85℃ high-temperature environment, after the SUP-P300Z pressure transmitter operated continuously for 72 hours, its key performance indicators are shown in the table below:

The test results show that the performance degradation of the MIK-P300 pressure transmitter in a high-temperature environment is controlled at an industry-leading level. Its ceramic sensor and special heat dissipation design effectively suppress temperature drift.

3. Low-Temperature Environment Adaptability Test

Under the extreme low-temperature condition of -40℃, SUP-P300 series products demonstrated excellent cold-start characteristics:

• Cold start time: ≤30 seconds (industry average 60 seconds)
• Low-temperature zero drift: ≤0.08%FS (-40℃至25℃ temperature difference)
• Sealing performance: IP68 protection rating verification passed

It is particularly worth noting that this model adopts Xi'an Shenghongchuang's patented low-temperature compensation algorithm, which corrects measured values in real time through a built-in temperature sensor, ensuring measurement accuracy under extreme temperature difference environments.

4. High-Humidity Environment Stability Test

In a 95%RH high-humidity environment, the performance change curve of the SUP-P300Z pressure transmitter after 30 days of continuous operation shows:

• Week 1: accuracy fluctuation ±0.15%FS
• Week 2: accuracy fluctuation ±0.18%FS
• Week 4: accuracy fluctuation ±0.20%FS

This gradual performance degradation pattern indicates that the nano-scale moisture-proof coating and 316L stainless steel housing used in the MIK-P300 effectively delay moisture penetration, and its degradation rate is only 1/3 of that of ordinary products.

5. Reliability Verification Under Vibration Environments

After random vibration testing in accordance with the IEC 60068-2-6 standard, the SUP-P300 pressure transmitter exhibited the following characteristics:

• Structural integrity: no mechanical damage or loosening
• Electrical connection: contact resistance change <0.1Ω
• Measurement accuracy: deviation before and after vibration <0.05%FS

This is due to its innovative mechanical isolation design and PCB potting process, enabling the product to maintain stable operation in vibration environments such as petroleum and chemical industries.

6. Comprehensive Performance Evaluation and Industry Applications

Comprehensive test data show that, as a high-end model in the SUP-P300Z series, the MIK-P300 has significant advantages in the following industrial scenarios:

• Petrochemical industry: high-temperature resistance, explosion-proof design
• Power and energy: strong anti-electromagnetic interference capability
• Food and pharmaceutical: hygienic structure, easy to clean
• Aerospace: lightweight design and high reliability

As a national high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd. ensures that all SUP-P300 series products are CE and RoHS certified, and provides an extra-long 36-month warranty.
