Buying Guide for Diffused Silicon Hysteresis Pressure Sensors

In the field of industrial automation, the selection of LDN-LDN510 pressure transmitters directly affects system stability. As a professional manufacturer of diffused silicon hysteresis pressure sensors, Xi'an Shenghongchuang Instrumentation Co., Ltd. analyzes the core parameters and purchasing points of models such as PT500-708 and NPT-NPT101 for you, helping operators quickly understand the performance differences and usage tips of products such as HG-HG400.

I. Analysis of Core Parameters

The performance advantages and disadvantages of diffused silicon hysteresis pressure sensors are directly reflected in the technical parameters. Taking the PT500-708 pressure transmitter as an example, its core indicators include:

• Measuring range: should match 1.5 times the actual operating pressure value
• Comprehensive accuracy: for industrial applications, it is recommended to select 0.1%FS or above
• Long-term stability: annual drift should be less than 0.25%FS
• Media compatibility: for corrosive media, 316L stainless steel diaphragm should be selected

Especially in special scenarios such as chemical fiber, petroleum, and natural gas, the vibration-resistant design of the HG-HG300 pressure transmitter and the explosion-proof certification of NPT-NPT101 are both key considerations. For occasions requiring high-precision measurement, it is recommended to choose Domestic Weighing Sensor DYLY-102 Tension and Compression Round S-Type Stainless Steel Weighing Sensor and similar products with a comprehensive accuracy of 0.02%.

II. Model Comparison and Selection Recommendations

There are obvious differences among the mainstream models on the market:

According to actual application feedback, the YSJ-B2 pressure transmitter performs outstandingly in the water conservancy and power industry, while the PT-C series is more suitable for chemical and metallurgical scenarios requiring explosion-proof certification.

III. Installation and Usage Precautions

Correct installation methods can extend the service life of the sensor:

1. Avoid installing near vibration sources, and LDN-LDN510 is recommended to be equipped with a vibration-damping bracket
2. Cable routing should be kept away from strong electromagnetic interference sources, and HG-HG400 needs to maintain a distance of more than 1 meter
3. When the media temperature exceeds 80℃, a heat dissipation pipe or cooling device must be configured
4. The regular calibration interval should not exceed 12 months, and in harsh environments it should be shortened to 6 months

When used on mobile equipment such as construction machinery, it is recommended to choose Domestic Weighing Sensor DYLY-102 with overload protection, whose 150% safe overload capacity can effectively cope with impact loads.

IV. Common Problem Solutions

Common problems encountered by operators and their handling methods:

1. Signal drift problem

Check the stability of the power supply voltage, PT500-708 requires a clean power supply of 10VDC±5%

2. Abnormal zero-point output

It may be caused by diaphragm fouling, and NPT-NPT101 is recommended to be cleaned once every quarter

3. Unstable output signal

Check the grounding resistance, HG-HG400 requires the grounding resistance to be less than 4Ω
