As a professional manufacturer in the field of diffused silicon liquid and gas pressure sensors,we provide you with multiple models of pressure transmitters such as YM-DJYJ,KS-E-E-Z-B01C-M-V. Whether you need to understand the working principle and selection guide of diffused silicon sensors,or are looking for genuine purchasing channels,this article will provide you with detailed answers.
Diffused silicon liquid and gas pressure sensors use the semiconductor piezoresistive effect principle,achieving precise measurement through the resistance change of single-crystal silicon material under pressure. Taking the KE-240-400BG5M pressure transmitter as an example,its core component is a silicon diaphragm. When the pressure of the measured medium acts on the diaphragm,the Wheatstone bridge outputs a millivolt signal proportional to the pressure,which is processed by temperature compensation and amplifier circuits to output a standard 4-20mA signal. Compared with traditional capacitive sensors,diffused silicon technology offers advantages such as high sensitivity(typical value 0.1%FS)and good long-term stability(±0.1%/year),making it especially suitable for fields with stringent accuracy requirements,such as petrochemical and pharmaceutical manufacturing.
In natural gas transmission and distribution systems,the P-UA pressure transmitter adopts a fully welded structure to prevent gas leakage. During installation,please note:1)the pressure tapping port should be located on the upper half of the pipeline to avoid condensate accumulation;2)shock-absorbing brackets should be added in vibration environments;3)outdoor installation requires a sunshade and rainproof cover. In the application of the MBS-G5734 model in cleanrooms in the pharmaceutical industry,its hygienic clamp connection design complies with the 3-A Sanitary standard and can meet the requirements for periodic steam sterilization. Special reminder:diffused silicon sensors are sensitive to overload,the system must be equipped with a safety relief valve,and the working pressure must not exceed 150% of the measuring range.
There are cases in the market where refurbished GT-V pressure transmitters are passed off as original factory products. To identify authenticity,please note:1)the laser engraving on the original product housing is clear and free of burrs;2)the circuit board has an anti-counterfeit coating and a unique serial number;3)a calibration certificate from a metrology institute is included in the package. As an authorized manufacturer of models such as 9SGC-7B4FM,we provide genuine product verification service with three codes matched as one(body code,package code,certificate code). When purchasing,it is recommended to require suppliers to provide qualification documents such as ISO9001 quality management system certification,SIL2 functional safety certificate,and third-party test reports(such as SGS).
Q:How to choose between diffused silicon and ceramic piezoresistive sensors?
A:Diffused silicon is suitable for medium and low temperature environments of -40~125℃ and offers higher accuracy;ceramic sensors can withstand temperatures up to 200℃ but have slightly poorer linearity. For high-temperature operating conditions such as chemical reactors,the KS-E-E-Z-B04U-M-V ceramic version is recommended.
Q:How to troubleshoot signal drift?
A:First check the power supply stability(fluctuation should be <1%),then eliminate the influence of mechanical vibration. If long-term drift exceeds 0.2%/year,factory calibration is required. We provide free calibration service within the 5-year warranty period.
Q:Is it suitable for measuring micro pressure(<10kPa)?
A:It is recommended to choose the dedicated low-pressure model YM-DJYJ,which adopts a dual-diaphragm differential pressure structure,can measure as low as 0.5kPa,and has a resolution of 0.01%FS.
As a national high-tech enterprise with 18 years of R&D experience in diffused silicon sensors,we have:1)fully automatic laser welding production lines(yield rate 99.8%);2)full-temperature-range compensation technology from -30℃~80℃;3)a 48-hour rapid response service system. All products leaving the factory undergo 72-hour aging tests and 100% pressure cycle tests,and on-site technical guidance is provided. Call 400-xxx-xxxx now to get an exclusive quotation plan for models such as KS-E-E-C-B01C-M-V,and enjoy a three-year extended warranty service for bulk purchases.
