Introduction

The accuracy class selection of the MBS33-060G3040 pressure transmitter with diffused silicon Hesmann pressure sensor directly affects the reliability of measurement data. As a core product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this article shares 3 key tips to help commercial evaluation personnel quickly determine the matching degree between the accuracy class and operating conditions based on the characteristics of models such as DMK331-250-6001, thereby optimizing procurement decisions.

1. Understanding the core parameters of the accuracy class

When evaluating the accuracy class of the MBS33-060G3040 pressure transmitter, the following technical indicators should be prioritized:

• Linearity error: Indicates the maximum deviation between the output signal and the ideal straight line, usually expressed as a percentage of full scale (%FS). For example, the typical value of model DMK331-250-6001-1-5-100-H00-1-B-2-000 is ±0.1%FS
• Repeatability: The consistency of data from multiple measurements under the same conditions, with the MBS33 series generally reaching ±0.05%FS
• Temperature effect: The zero-point drift caused by every 10℃ change in operating temperature, which can be controlled within ±0.02%FS by diffused silicon technology

Compared with similar products such as domestic CHBX1 cantilever beam load cell with a combined accuracy of 0.02～0.03%, Hesmann sensors have greater advantages in dynamic pressure measurement scenarios.

1.1 Balance between accuracy class and cost

According to the ISO 9001 standard, we recommend selecting according to the following principles:

2. Analysis of operating condition environment matching

The selection of the measuring range for models such as MBS33M-060G1705 needs to consider:

1. Medium characteristics: Corrosive media should use a 316L stainless steel diaphragm, which is consistent with the material selection logic of the alloy steel used in the CHBX1 sensor
2. Vibration interference: For scenarios such as oil and gas pipelines, it is recommended to configure a damper, which can reduce the failure rate of MBS33-060G3017 by 67%
3. Temperature compensation: For operation in the wide temperature range of -20℃～+65℃, it is necessary to verify the temperature compensation circuit design in the wiring diagram of E913-033-B24R

2.1 Typical fault prevention solutions

For the common zero-point drift issue during calibration of MBS33-060G3013:

• Carry out a 24-hour aging test before installation
• Perform on-site calibration regularly in accordance with JJG 882-2019 procedures
• Select the dedicated signal conditioner for MBS33-060G3011 for matching instruments

3. Full life cycle cost calculation

When evaluating the service life of MBS33M-060G1234, the following should be calculated:

• Procurement cost: High-accuracy models are usually priced 30-50% higher than standard models
• Maintenance cost: Adopting the preventive maintenance plan in the instructions for use of MBS33-060G3041 can extend MTBF to 8 years
• Failure cost: In the chemical and metallurgical industries, production shutdown losses caused by sensor failure can reach ten thousand yuan/hour

Summary and recommendations

When selecting the accuracy class of the MBS33-060G3040 pressure transmitter, it is recommended that commercial evaluation personnel: 1) select the most cost-effective accuracy grade according to process requirements; 2) strictly match the characteristics of the operating condition environment; 3) adopt a full life cycle cost model for decision-making.
