Introduction

In the field of industrial flow control, the selection of the HK-613 pressure transmitter directly affects system stability. As a professional manufacturer of diffused silicon sensors, Xi'an Shenghongchuang Instrumentation will analyze the 3 key performance indicators you must consider when purchasing diffused silicon liquid and gas pressure sensors, helping you quickly match the precise requirements of models such as BTL-BTL70 and CYB-20SA.

1. Accuracy and Stability: The Core Indicators of Diffused Silicon Sensors

The accuracy of diffused silicon pressure sensors directly determines the measurement reliability of the HK-613 pressure transmitter. According to ISO 9001 standards, high-quality diffused silicon sensors should meet the following requirements:

• Non-linearity error ≤0.1%FS: ensure that models such as BTL-BTL70 maintain linear output within the full scale range
• Repeatability error ≤0.05%: CYB-20SA needs to maintain data consistency in multiple measurements
• Temperature drift coefficient ≤0.01%/℃: cope with industrial environmental fluctuations from -40℃~125℃

Xi'an Shenghongchuang's SK1151-33X series uses military-grade silicon chips and has passed 2000-hour aging tests, with its independent linearity reaching 0.05%, far exceeding the industry average.

1.1 Long-term Stability Verification Methods

It is recommended to verify the stability of models such as LYB-LYB3008 through the following methods:

2. Media Compatibility and Sealing Design

Models such as DET-131 need to adapt to different operating media, and special attention should be paid to the following when selecting them:

1. Wetted material: 316L stainless steel diaphragm can withstand corrosion from acidic and alkaline media
2. Sealing grade: IP68 protection and welded sealing structure ensure long-term leak prevention
3. Pressure port: interfaces such as G1/4" and NPT1/2 need to match the existing piping system

For high-pressure environments such as injection molding machines, it is recommended to use domestic TLH slider electronic ruler displacement sensor together as a set. Its conductive plastic film material and IP67 sealing grade can perfectly match the installation requirements of HK-613.

2.1 Special Media Handling Solutions

Application recommendations for ND-1 in the following scenarios:

• Viscous media: install a diaphragm isolator
• High-temperature steam: configure heat dissipation fins and capillary tubes
• Corrosive liquids: use Hastelloy wetted parts

3. Signal Output and System Integration

The signal processing capability of models such as KD-KD201 directly affects the accuracy of the control system:

• Output type: 4-20mA/0-10V signals need to match the PLC acquisition module
• Response time: rapid response of ＜1ms is suitable for dynamic pressure monitoring
• EMC protection: passed IEC 61000-4-3 Level 4 electromagnetic compatibility testing

When used together with TLH series displacement sensors, it is recommended to adopt an RS485 bus architecture, and its wide operating voltage design of 5-24VDC can simplify the power supply system.

Summary and Action Recommendations

When purchasing diffused silicon pressure transmitters such as HK-613/JYB-KO-M, it is recommended to prioritize: 1）measurement accuracy of 0.05 class or above; 2）sealing protection of IP67 or above; 3）standardized signal output interfaces.
