Introduction

As a commonly used HG-HG300 pressure transmitter in the field of industrial automation, although it delivers stable performance, there are still 3 key pain points in actual use. This article will provide an in-depth analysis of the shortcomings of this diffused silicon Hirstman pressure sensor, helping operators avoid potential problems and improve equipment efficiency.

3 Major Usage Pain Points of the HG-HG300 Pressure Transmitter

As a common measurement device in industrial automation, the HG-HG300 pressure transmitter is known for its high accuracy and stability. However, during practical application, operators often encounter certain specific issues that may affect the performance and service life of the device. The following is a detailed analysis of the main shortcomings of the HG-HG300 pressure transmitter:

1. Temperature Drift Issue

Although the diffused silicon technology used in the HG-HG300 pressure transmitter offers high sensitivity, it is relatively sensitive to temperature changes. In extreme temperature environments (especially under operating conditions exceeding 100℃), the sensor is prone to output signal drift.

Solution:

• Select a model with temperature compensation function
• Add heat dissipation devices in high-temperature environments
• Perform regular zero-point calibration

By comparison, Domestic displacement sensor KTM-F slider electronic ruler die-casting machine injection molding machine slider resistance ruler linear displacement sensor uses special conductive plastic material and can maintain stable performance within the range of -60℃ to +150℃, with no temperature drift.

2. Medium Compatibility Limitations

The diaphragm material of the HG-HG300 has limited resistance to certain corrosive media, and long-term contact with strong acids, strong alkalis, or organic solvents may cause damage to the measuring diaphragm.

Key precautions:

• Confirm the medium characteristics before purchase
• Consider adding an isolation diaphragm
• Regularly inspect the diaphragm condition

In contrast, the PTB-PTB203 pressure transmitter uses more corrosion-resistant 316L stainless steel material, making it more suitable for special environments such as the chemical industry.

3. Installation and Maintenance Complexity

The HG-HG300 has relatively high requirements for installation position and method. Incorrect installation may lead to measurement errors or equipment damage. Meanwhile, its internal structure is relatively complex, making on-site maintenance more difficult.

Best practices:

• Strictly follow the manufacturer's installation guidelines
• Use dedicated installation tools
• Establish a regular maintenance plan

For applications requiring frequent maintenance, the modular design of the KY-2 pressure transmitter may be more suitable.

How to Avoid Usage Risks of the HG-HG300

In response to the above pain points, operators can take the following measures to improve the effectiveness of the HG-HG300:

Recommendations for Selecting Diffused Silicon Pressure Sensors

When selecting a diffused silicon Hirstman pressure sensor, in addition to considering the HG-HG300, the following factors should also be evaluated according to actual needs:

• Operating temperature range
• Medium characteristics
• Accuracy requirements
• Installation environment
• Budget constraints

For equipment such as die-casting machines and injection molding machines, Domestic displacement sensor KTM-F is also a worthwhile option due to its excellent sealing performance (IP67) and wide temperature applicability range (-60～+150℃).

Summary and Action Recommendations

As an important part of industrial automation, although the HG-HG300 pressure transmitter has issues such as temperature sensitivity, medium compatibility, and installation complexity, its high-accuracy advantages can still be leveraged through correct usage methods and preventive measures. For special operating conditions, other models or types of sensors may be considered, such as PT500-708 and NPT-NPT101.
