5 Core Criteria for Selecting Diffused Silicon Hesseman Pressure Sensors

In the field of industrial automation control, the accuracy and reliability of diffused silicon Hesseman pressure sensors directly affect system performance. As the core component of pressure measurement, how should models such as the MBS33M series and PT124B be selected? This article approaches the topic from 5 professional criteria including range accuracy and media compatibility, helping technical evaluators quickly match parameters of models such as PTX5072 and solve calibration and selection challenges.

1. Range and Accuracy: The Primary Indicators for Matching Process Requirements

The 0.1%FS high-accuracy characteristic of the MBS33M-060G3130 pressure transmitter keeps the error within only ±0.01MPa over a 10MPa range. Technical evaluation should focus on:

• Overload capacity: The PT124B-210-10MPa-M20 model features 150% range overload protection
• Temperature compensation: 7MF15643CA00-1AA1 adopts full-temperature-range compensation technology(-40~125℃)
• Long-term stability: MBS33-060G3061 annual drift is ＜0.2%FS/year

It is recommended to select a model with a range 1.5 times the actual working pressure, for example, PT124B-210-2.5MPa-M20 is suitable for 1.6MPa operating conditions.

2. Media Compatibility: A Decisive Factor in Material Selection

The 316L stainless steel diaphragm of the PTX5072-TC-A1-CA-H0-PB pressure transmitter can withstand strongly corrosive media:

3. Output Signal and System Integration

The MBS33M-060G3124 pressure transmitter provides dual output of 4-20mA+HART protocol and can seamlessly interface with domestic instrument NHR1120 temperature detection alarm digital display control instrument controller. Key parameters include:

• Response time ＜1ms（PTX5072 series）
• Load capacity ＞600Ω（complies with IEC 60381 standard）
• EMC immunity reaches EN 61326 Class A

4. Environmental Adaptability and Protection Rating

Operating characteristics of the 7MF15643CA00-1AA1 pressure transmitter:

• IP67 protection rating（can withstand short-term immersion）
• Wide-temperature operation from -40~85℃
• Vibration resistance 5g@10-2000Hz

5. Convenience of Calibration and Maintenance

The PT124B series supports on-site calibration:

1. Adjust zero point/full scale via HART handheld communicator
2. M20 interface standardly equipped with pressure relief valve
3. Modular design allows replacement time of ＜15 minutes
