Horizontal Comparison of Technical Parameters of Mainstream Diffused Silicon Pressure Transmitters in 2023

In 2023, the diffused silicon pressure transmitter industry ushered in technological upgrades, and mainstream models such as DG1300-PJ-1-CJ/GK/GZ and CR-YM2 achieved breakthroughs in accuracy and stability. Aimed at the needs of technical evaluators, this article horizontally compares the technical parameters, installation methods (such as the JM-2010-5M installation guide), and maintenance points (including the MBS4701 maintenance specification) of 10 products such as MPM489E22B1C2G and BP-H, helping you quickly grasp the key points for selecting differentiated functions such as alarm control and remote signal transmission.

1. Market Status and Technology Evolution Trends

According to the latest data from the International Society of Automation (ISA), the global diffused silicon pressure transmitter market size is expected to reach $4.2 billion in 2023, of which China's market share will increase to 28%. As a national-level sensor industry base, Xixian New Area has formed a complete industrial chain ecosystem. Represented by domestic equipment such as domestic general-purpose pressure transmitter WY-M hydraulic oil pneumatic sensor, domestic products have already matched international brands in key technical indicators such as 0.1% high accuracy and a wide temperature range of -40～+400℃. The industry currently shows three major trends: diversified signal outputs (4-20mA/RS485/HART protocols coexisting), structural miniaturization (for example, the size of MPM489E22B1C2G is 30% smaller than the previous generation), and intelligence (the CLG-D model comes standard with the Modbus communication protocol).

3. Key Selection Guide

Technical evaluation points for different application scenarios:

• Chemical industry: give priority to the 316L stainless steel material of the BP-H model, whose corrosion resistance is certified by NACE MR0175
• Power systems: FST800-211P341I-10B comes standard with an electromagnetic interference resistance design, complying with the IEC 61000-4-3 standard
• Mobile equipment: JM-2010-5M uses a compact M20×1.5 threaded interface, suitable for space-constrained scenarios
• Process control: PX-BACHX supports dual outputs of 4-20mA+RS485, meeting the redundancy requirements of DCS systems

4. Professional Recommendations for Installation and Maintenance

According to the installation instructions of the KYB-C1 pressure transmitter, special attention should be paid to:

1. The installation position should avoid vibration sources, with vibration acceleration ≤5g
2. When the medium temperature exceeds 120℃, a heat sink or capillary tube should be installed
3. The maintenance specification of MBS4701-060G5811 requires zero-point calibration every 6 months
4. The CLG-D model with alarm control requires regular testing of relay contacts
