Analysis of core parameters of diffused silicon pressure transmitter

As a core component of industrial flow control, the YM-130 pressure transmitter's diffused silicon sensor parameters directly affect measurement accuracy and stability. This article will provide an in-depth analysis comparing the specifications of models such as the YM-130, from the cost-effectiveness of the YSZK-01G-C to the calibration method of the DMK331, helping users resolve selection dilemmas and troubleshooting problems.

1. Technical advantages of diffused silicon sensors

Diffused silicon pressure sensors are renowned for their superior stability and accuracy, and are widely used in industries such as petroleum, chemical, and power. Compared to traditional sensors, diffused silicon technology offers higher sensitivity (typically reaching 0.1%FS) and a wider temperature compensation range (-40 to +400℃). Taking the YM-130 as an example, its 316L stainless steel diaphragm is compatible with most non-corrosive media, and combined with industrial-grade overload protection design, it can meet the requirements for long-term stable operation under harsh conditions.

When selecting a diffused silicon sensor, three key indicators should be considered: measurement range (e.g., the SDP6A00 series offers a selectable range of -0.1 to 100 MPa), output signal type (4-20mA/0-10V, etc.), and media compatibility. For special applications such as high-temperature media measurement, it is recommended to choose products specifically optimized for temperature performance, such as the domestically produced general-purpose pressure transmitter SDP6A00 water, oil, and air pressure sensors .

2. Horizontal comparison of mainstream models and specifications

As can be seen from the comparison table, different models have significant differences in price positioning. For example, the YSZK-01G-C, with its 0.5% accuracy and moderate measuring range, is the top choice for cost-effectiveness; while the DMK331 series meets precision control requirements with its ultra-high accuracy of 0.1%. Users should select the measuring range according to the actual pressure fluctuation range of the working conditions (it is recommended that the working pressure be in the range of 60%-80% of the measuring range).

3. Calibration Methods and Troubleshooting Guide

Calibration of models such as YMP-YMP489 must follow the ISO 9001 standard procedure: First, input the 25%/50%/75%/100% range points through a standard pressure source, and then use a precision ammeter to check the output signal deviation. When common faults of YM-115 such as zero-point drift occur, check whether the power supply voltage is stable (24VDC±5% recommended), or check for diaphragm blockage caused by medium crystallization.

For abnormal display issues with the MBS-G3131, it is recommended to first verify the contact reliability of the electrical connections (Hirschmann connectors/aviation plugs, etc.). The working principle of diffused silicon sensors is based on the piezoresistive effect; when the YM-1QQ exhibits non-linear output, temperature compensation calibration is often required.

Key factors in selection decision

Based on a comprehensive evaluation of the YD-322's accuracy class and the technical specifications in the YM-1XH's instruction manual, it is recommended to make a decision based on four dimensions: 1) Media characteristics (corrosiveness/viscosity); 2) Ambient temperature (whether wide temperature compensation is required); 3) Installation method (threaded/flange); 4) Signal transmission distance (4-20mA is preferred for long distances). For special applications such as aerospace, products with multiple military certifications should be selected.

Xi'an Shenghongchuang Instruments Co., Ltd., a national high-tech enterprise, has successfully applied its pressure transmitter series to key national projects such as the West-East Gas Pipeline.
