FST800-211P341I-25B Pressure Transmitter Price and Technical Evaluation Guide

When selecting diffused silicon pressure transmitters such as FST800-211P341I-25B，accurately understanding the balance between price and performance is critical。This article provides an in-depth analysis of the quotation patterns of multiple sensor models（such as MPM489/HM27G/SS302 series），and compares the factory-direct supply advantages of products such as DG1300/HR-M1KF2AN3，providing core data for purchasing decisions by technical evaluators。

I、Market Status and Price Range of Diffused Silicon Pressure Transmitters

In the current industrial sensor market，the price of diffused silicon liquid and gas pressure sensors such as FST800-211P341I-25B usually fluctuates within the range of 800-3000 yuan，depending on the measuring range（for example，the MPM489(0-10mH2O)E22B2C1G model is suitable for low-pressure scenarios），material grade（316L stainless steel carries a 15%-20% premium over ordinary stainless steel）and certification standards（such as CE/ATEX certification increasing costs by 10%-30%）。Domestic brands represented by SS-SS302 have an average price of around 1200 yuan，while imported models such as HR-K2SJG1F2AF generally exceed 2500 yuan。It is worth noting that，Domestic General-Purpose Pressure Transmitter PTS705 Water Pressure Oil Pressure Air Pressure Sensor，with 0.1% high accuracy and a wide temperature range of -40～+400℃，has shown a trend of replacing imported products in the petrochemical field。

II、Core Parameter Comparison and Key Points for Technical Selection

Technical evaluators should focus on the following performance indicators：1）accuracy class（HR-M1KF2AN3 can reach 0.25%FS）；2）medium compatibility（DG1300-PJ series adopts a special diaphragm treatment process）；3）temperature compensation range（PS6000-VB-BZ-A1-A-30/FZ model supports full compensation from -30℃~+120℃）。Comparative testing shows that DMP331-110-6000-3-5-100-300-1-000 offers better long-term stability than similar products in 6000psi high-pressure scenarios，while HM27G-1-A1-F1-W2 performs outstandingly in small-range（0-1MPa）applications。For users requiring customized services，it is recommended to directly contact the HR-M1KF2AN3 pressure transmitter manufacturer by phone to obtain a technical solution。

III、Procurement Strategies and Cost Optimization Solutions

For bulk purchasing，series products such as FST800-211P341I-16B can reduce costs by 15%-25% through factory-direct sales channels。Technical teams are advised to：1）give priority to models supporting both G1/2 and M20*1.5 connection standards（such as the PTS705 series）；2）consider the economical 2088 junction box version for non-corrosive media；3）pay attention to the 3-year extended warranty service provided by manufacturers。A shipbuilding enterprise replaced imported products with Domestic General-Purpose Pressure Transmitter PTS705 Water Pressure Oil Pressure Air Pressure Sensor，reducing procurement costs by 42% while meeting the 1.6MPa measurement requirement。

IV、Technical Q&A and Common Misconceptions

Q：How to choose between diffused silicon and ceramic piezoresistive sensors？
A：Diffused silicon sensors（such as the FST800 series）offer better linearity within the -0.1~100MPa range，while ceramic sensors are more suitable for media containing solid particles。
Q：Why does the price of SS-SS302 differ by up to 40% among different manufacturers for the same model？
A：The key differences lie in the temperature compensation process（the wider the compensation range，the higher the cost）and the sealing structure（welded type is 20%-30% more expensive than O-ring type）。
Q：The 4-20mA output signal of PS6000-VB-BZ-A1-A-30/FZ is unstable？
A：Check whether the power supply voltage is stable at 24VDC±10%，and eliminate electromagnetic interference（shielded cables are recommended）。

V、Industry Trends and Professional Recommendations

With the increasing adoption of IEC 61508 functional safety certification in the process control field，technical teams are advised to give priority to models such as HR-K2SJG1F2AF that have passed SIL2 certification。For special scenarios such as aerospace，special attention should be paid to the medium temperature range（PTS705 supports up to +400℃）and vibration resistance performance（≥5g RMS）。We provide free technical consultation and sample testing services。Click to obtain the FST800-211P341I-25B pressure transmitter company phone number and get a dedicated solution。
