Key Customization Factors for Diffused Silicon Hirschmann Pressure Sensors

In the field of industrial automation, the demand for customized 7MF-MF1567 pressure transmitters is growing steadily. As a professional supplier of flow control equipment, Xi'an Shenghongchuang Instrument Co., Ltd. analyzes the 3 major customization points of diffused silicon Hirschmann pressure sensors for you, helping technical evaluators make accurate selections. This article will introduce in detail the customization solutions for 7MF-MF1567 pressure transmitters to help you achieve the best performance match.

Diffused silicon Hirschmann pressure sensors are widely used in harsh environments such as petrochemical and electric power industries due to their excellent stability and accuracy. For technical evaluators, the selection of measurement range, material compatibility, and signal output configuration during the customization process are the three core considerations.

1. Precise Matching of Measurement Range and Turndown Ratio

The 7MF-MF1567 series provides a wide range coverage from 0-0.2kPa to 10MPa, and its unique 40:1 turndown ratio is significantly superior to industry standards. In scenarios such as vacuum monitoring in power systems or high-pressure pipelines in petrochemical applications, special attention should be paid to:

• Vacuum Environment Adaptation：Range 3 (0-0.2~6.0kPa) adopts a special diaphragm design and can withstand an overpressure limit of 13.76MPa
• High-Temperature Compensation：For ranges 6~8, within the medium temperature range of -40~100℃, the zero-point error is controlled within ±0.5%/55℃
• Static Pressure Correction：For static pressure systems above 6.89MPa, it is recommended to enable the preset static pressure compensation algorithm

Compared with the domestic capacitive pressure transmitter PCM1151, diffused silicon sensors offer better volumetric change (＜0.16cm³) in micro-pressure measurement, making them particularly suitable for precision control in hydraulic systems.

2. Corrosion Protection Solutions for Material Combinations

For different medium characteristics, we provide multiple material combination solutions:

In metallurgical industry applications, the TS-TS205 pressure transmitter with a 42CrMo alloy body has passed a 3000-hour salt spray test, and its explosion-proof structure complies with the Exd Ⅱ CT6 standard.

3. Intelligent Signal Output Configuration Strategy

Modern industrial sites have put forward higher requirements for signal transmission:

• HART Protocol Integration：Supports synchronous transmission of 4~20mA analog signals and digital communication
• Nonlinear Correction：Optional square root output mode, maintaining linearity in the 0%~0.1% low range segment
• Remote Diagnostics：Real-time monitoring of diaphragm health status through the self-diagnostic function of the YSJ-B3 transmitter

For models such as VP-VP461 that require explosion-proof certification, it is recommended to configure an intrinsically safe Exia Ⅱ CT6 circuit, and its 14.5~45V wide voltage input can adapt to unstable power supply environments.
