Which DG1300-BZ-B-2-300 pressure transmitter supplier is cheaper？Factory direct sales save 30%

Looking for factory-direct DG1300-BZ-B-2-300 pressure transmitters？We professionally manufacture diffused silicon pressure sensors for liquids and gases，with one-stop supply of models such as AST-E1117、PT500-50M，eliminating middleman markups and passing on 30% savings directly。Whether it is JX-004 or MYR-22，we provide high-precision pressure transmitters at factory-direct prices，addressing your core needs of ‘which supplier is cheaper’ and ‘which supplier offers better quality’。

I、Analysis of the core advantages of diffused silicon pressure transmitters

The DG1300-BZ-B-2-300/CJ/GZ pressure transmitter adopts diffused silicon sensing technology，with core advantages of 0.1%FS high accuracy and ±0.5% annual stability。Compared with traditional piezoresistive sensors，diffused silicon elements form a Wheatstone bridge on the silicon wafer surface through semiconductor processing，delivering a superior linear response to liquid/gas pressure。Our factory-produced AST-E1117 series is ISO9001 certified，with an operating temperature range of -40~125℃，making it especially suitable for harsh environments such as petrochemical pipelines and hydraulic systems。Actual test data show that the PT500-50M-10V-0.5-M20-3m-503 model still maintains ±0.3% accuracy after 100,000 pressure cycles，far exceeding the industry average。

II、Five major application scenarios and model selection guide

For different media characteristics，the YM-YM300 model is specially equipped with a ceramic isolation diaphragm design，enabling measurement of highly corrosive media；while the MYR-22 has a built-in temperature compensation chip，maintaining stable output even when the ambient temperature fluctuates from -20~80℃。During procurement，key attention should be paid to the measuring range（it is recommended to select 1.5 times the actual operating pressure）、output signal（4-20mA/0-10V/RS485）and process connection type（G1/4、NPT1/2，etc.）。

III、Authenticity and quality identification and procurement pitfall avoidance guide

There is an issue of refurbished chips in KYB-G pressure transmitters on the market，which can be identified through three points：1) The bridge resistance value of a genuine diffused silicon sensor should be within the range of 3-6kΩ；2) The depth of laser engraving on the housing should be ≥0.2mm；3) The original manufacturer provides a HART protocol communication test report。Our actual tests show that the EMC performance of the ZY800-V1-B1-C1-J1P1 model meets the EN 61326-1 standard，with an error of ≤1% in RF field immunity within the 80MHz-1GHz frequency band。Users are advised to require suppliers to provide calibration certificates issued by third-party metrology institutes，with particular attention to zero-point temperature drift（≤±0.03%FS/℃）and long-term stability indicators。

IV、Technical Q&A and after-sales service commitment

Q：How to determine whether a pressure transmitter needs to be replaced？
A：Replacement should be considered when the following situations occur：1) Zero-point drift exceeds 1% of the range；2) The output signal shows step changes；3) Medium leakage occurs at the sealing ring。Our DG1300 series provides a 3-year warranty，and all models support a 48-hour rapid replacement service。
