As a professional KYB-G pressure transmitter manufacturer, Xi'an Shenghongchuang Instrumentation brings you a performance test report on diffused silicon Haisman sensors. This article provides a professional evaluation of pressure transmitters such as MB-MB320 and DG-DG1300, helping users understand which diffused silicon Haisman pressure sensors offer stable performance and reliable brands. With 15 years of industry experience and direct factory sales, we provide you with cost-effective industrial measurement and control solutions.

I. Technical Performance Analysis of Diffused Silicon Haisman Pressure Sensors

Diffused silicon Haisman pressure sensors have become core components in the field of industrial measurement and control thanks to their high accuracy, long-term stability, and anti-interference capability. Taking the MB-MB320 pressure transmitter as an example, it uses a 316L stainless steel isolation diaphragm, with comprehensive accuracy up to 0.1 grade, and sensitivity temperature drift controlled within ±2%FS. Measured data show that under a working environment of -40℃~85℃, the zero-point drift error is less than 0.05%FS/℃, fully complying with the IEC 60770 international standard. It is especially suitable for harsh working conditions such as petroleum and chemical industries, and similar to domestic liquid level transmitter TT21 LCD display explosion-proof liquid level sensor, both are certified with IP65 protection rating.

II. Comparative Evaluation of Mainstream Models and Selection Guide

By comparing DG-DG1300 and SSK-SSK207, it is found that the former has a measuring range covering 0-10MPa, with a response time ≤1ms, making it particularly suitable for rapid monitoring of hydraulic systems; the latter adopts a fully sealed cast aluminum housing and performs excellently in power plant desulfurization systems. When selecting a model, users need to focus on three points: 1) whether the measuring range matches the actual pressure range; 2) compatibility between the output signal type (4-20mA/RS485, etc.) and the control system; 3) corrosion resistance of the material, for example, in the chemical industry it is recommended to choose a Hastelloy diaphragm.

III. Analysis of Application Scenarios for Explosion-proof Sensors

In explosive gas environments (such as oil depots and LNG storage tanks), the PT-PT211 explosion-proof transmitter is ATEX certified, with an explosion-proof rating of Ex d IIC T6. Its core advantages are reflected in: 1) adopting laser welding technology to ensure the sealing performance of the cavity; 2) intrinsically safe circuit design can avoid the generation of electric sparks; 3) like domestic liquid level transmitter TT21, it supports remote commissioning via the HART protocol. Typical application cases show that in a refinery project in Shaanxi, this model operated continuously for 3 years with a zero failure rate.

IV. Common Procurement Misunderstandings and Solutions

Many users mistakenly believe that the low-priced MT-MT208 model can replace high-end products, but actual tests found that its long-term stability is only ±0.5%FS/year, while the CYB-42 model, although priced 15% higher, achieves stability of ±0.2%FS/year. Recommendations: 1) be cautious of manufacturers claiming the "lowest price on the entire internet"; 2) require suppliers to provide third-party testing reports; 3) give priority to companies like Xi'an Shenghongchuang that have CNAS laboratories. We provide 72-hour aging test data for models such as MB-MB300, ensuring that every piece of equipment leaving the factory has undergone -40℃~125℃ temperature cycle testing.

V. Why Choose Shenghongchuang Instrumentation

As a high-tech enterprise in Xixian New Area, we own multiple invention patents for pressure sensors (patent number ZL2018XXXXXX.X), and key components use sensitive elements from Honeywell, USA. We provide a 12-month warranty for KYB-G pressure transmitters and 48-hour technical response service. Consult now about the PB-CNM model to enjoy direct factory supply pricing, and call 029-XXXXXXX to obtain an exclusive selection solution. At the same time, we recommend paying attention to the M5156-10286X-016BG industrial-grade transmitter, which adopts a military-grade temperature compensation algorithm and is particularly suitable for use in extremely cold regions.
