7 Practical Tips for Purchasing the HK-613 Pressure Transmitter

As a key component in industrial automation, the selection of the HK-613 pressure transmitter directly affects system stability. In this article, senior engineers from Xi'an Shenghongchuang Instrumentation share 7 practical tips to help you accurately select diffused silicon Hesmman pressure sensors and avoid common application mistakes with models such as DET-131. From media compatibility to output signal types, this article explains in detail the core purchasing considerations for product series such as KYBX.

1. Clarify the Measured Medium and Material Compatibility

In scenarios such as petrochemical and environmental protection industries, corrosive media will directly affect sensor service life. It is recommended to give priority to diffused silicon Hesmman pressure sensors made of 316 stainless steel, whose corrosion resistance is more than 30% higher than that of 304 stainless steel. For example, the domestic general-purpose pressure transmitter PD210H uses a 316L stainless steel isolation diaphragm, making it compatible with strong acids and alkalis, and especially suitable for pressure monitoring on chemical production lines.

2. Range Selection Must Consider Overload Protection

Common failures in models such as ND-1 often result from improper range selection. Engineers recommend:

• The working pressure should be within 60%-80% of the measuring range
• The overload pressure should reach 2 times the full scale range （up to 300MPa）
• Vacuum measurement requires a special range of -0.1MPa

The PD210H series provides full range coverage from 0.01MPa~250MPa, and its 0.25 accuracy class can meet high-demand scenarios such as laboratory calibration.

3. Verify Output Signal and System Compatibility

The ST-ST950 model once caused PLC misjudgment due to signal conflict. Be sure to confirm:

The KYBX-KYBX pressure transmitter supports switching among multiple signal outputs, making it compatible with more than 90% of industrial control systems.

4. Check Key Parameters for Environmental Adaptability

The failure rate of HR-M2 in high-temperature scenarios indicates:

• The medium temperature range must reach -30~85℃
• Ambient temperature compensation 0-70℃
• When humidity is ≤95%, IP65 protection is required

The temperature drift of the diffused silicon Hesmman pressure sensor is controlled within ±0.05%FS/℃, ensuring stability in high-temperature scenarios such as turbo-generator units.

5. Balance Between Accuracy Grade and Cost

The case of BP-BP200 shows:

1. Choose class 1.0 （±1%FS） for ordinary process control
2. Precision testing requires class 0.5 or class 0.25
3. Laboratory calibration must use class 0.1

PD210H offers an optional class 0.1 configuration, with annual stability of ±0.1%FS, delivering better cost performance than imported brands.

6. Standardization of Installation Method and Interface

The installation issues of LED-900 serve as a warning:

• Thread specifications must match standards such as M20×1.5/G1/4
• Aviation plugs are better than direct cable outlets
• Compact structures are more suitable for space-constrained scenarios

DET-131 adopts a modular design and supports quick replacement of different pressure interfaces.

7. Supplier Qualifications and After-Sales Service

Research shows that 68% of KD-KD201 failures originate from counterfeit products. Key points for identifying genuine products:

• Check ISO9001 certification
• Confirm an 18-month warranty period
• Require traceable laser coding

As a manufacturer of diffused silicon Hesmman pressure sensors, Xi'an Shenghongchuang provides professional technical support and spare parts assurance.

Summary and Action Recommendations

When selecting pressure transmitters such as HK-613, it is necessary to comprehensively consider seven major factors including medium characteristics, range accuracy, and environmental adaptability. For scenarios such as building automation and constant-pressure water supply, the domestic general-purpose pressure transmitter PD210H has become the preferred solution to replace imported brands, thanks to its 316 stainless steel material, 0.25 accuracy class, and multiple signal outputs.
