Analysis of Key Factors for Selecting Diffused Silicon HESSMAN Pressure Sensors

In the field of flow control equipment, the selection of the measurement range for the diffused silicon HESSMAN pressure sensor used in the MBS33M-060G1705 pressure transmitter is of critical importance. This article provides an in-depth analysis of key parameters of diffused silicon HESSMAN pressure sensors, including model specifications, accuracy grades, and measurement ranges, helping business evaluation personnel make accurate selections and avoid cost losses and project delays caused by choosing the wrong model.

1. The Relationship Between Measurement Range and Overload Capacity

The typical measurement range of model MBS33M-060G1705 is 0-1.7MPa, but actual selection must take the system peak pressure into consideration. Industrial-grade pressure transmitters usually have an overload capacity of 2 times full scale. For example, the domestic general-purpose pressure transmitter MT208 with a 0.6MPa range can withstand an instantaneous pressure of 1.2MPa. Special attention should be paid during business evaluation:

• Conventional operating conditions: select an upper range limit 30% higher than the maximum working pressure
• Pulsating operating conditions: reserve a margin of more than 50%
• Vacuum environment: select a model with negative pressure detection such as MBS33-060G3011

The 316L stainless steel diaphragm structure of the diffused silicon HESSMAN pressure sensor can withstand pressures from -0.1~100MPa, but the sealing method and connection specifications of different models (such as G1/4 or M20*1.5) will affect the actual application range.

2. The Correlation Between Accuracy Grade and Temperature Compensation

The MBS33 series offers multiple accuracy options from 0.1%~0.5%, but actual accuracy is significantly affected by temperature. Taking MBS33-060G3040 as an example:

For extreme environments such as aerospace, it is recommended to select models with wide-temperature compensation. For example, MT208 can still maintain 0.1% accuracy within the range of -40~400℃, and its temperature compensation technology can reduce thermal drift error by 90%.

3. Electrical Characteristics and Key Points for System Integration

The wiring method of the HESSMAN connector directly affects signal stability:

1. Model E913-033-B24R adopts a standard 4-20mA output, with a transmission distance of up to 1000 meters
2. For scenarios sensitive to power supply fluctuations, select wide-voltage models of 12-36VDC
3. For explosion-proof areas, intrinsic safety certification parameters must be confirmed

The selection of supporting instruments is equally critical. MBS33-060G3011 is recommended to be paired with an acquisition module with a resolution of ≥16 bits, while the DMK331 series, due to different output signal characteristics, needs to be matched with a dedicated signal conditioner.

4. Media Compatibility and Service Life Evaluation

Although the 316L stainless steel diaphragm of the diffused silicon sensor is corrosion-resistant, different media still have special requirements:

• When chloride ion content exceeds 25ppm, a Hastelloy isolation diaphragm should be added
• For viscous media, select MBS33-060G3060 with flange mounting
• For the food and pharmaceutical industries, hygienic clamp quick-connect fittings are preferred

According to accelerated life test data, under rated operating conditions, the mean time between failures of MBS33M-060G1234 can reach 5 years, but actual service life is affected by the following factors:

Selection Decision Tree and Professional Recommendations

Based on experience from 200+ industrial projects, it is recommended that business evaluation personnel make decisions according to the following process:

1. Confirm media characteristics and temperature range
2. Calculate the maximum working pressure and safety margin
3. Select matching electrical connections and output signals
4. Evaluate installation method and protection rating
5. Verify the compatibility of supporting instruments

For special operating conditions such as high pressure and high temperature, the domestic general-purpose pressure transmitter MT208 with its 100MPa range and 400℃ temperature resistance can provide a more cost-effective solution. As a national high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd. can provide customized selection verification services for each project.
