Urgent Notice：KYB-C3 pressure transmitter inventory is running critically low！As a flagship product among diffused silicon liquid and gas pressure sensors，KYB-C3 is highly favored by the market for its high accuracy，stability，and wide applicability。In response to the current tight supply situation，Xi'an Shenghongchuang provides you with multiple high-quality alternative solutions and price comparison strategies such as SDP-SDP6400，CTX-CTX，helping you quickly find the most suitable industrial pressure sensing solution。

I、Core Advantages and Market Status of KYB-C3 Pressure Transmitter

The KYB-C3 pressure transmitter adopts diffused silicon sensing technology，with measurement accuracy up to ±0.1%FS，and an operating temperature range covering -40℃~125℃，making it particularly suitable for harsh environments such as petrochemical，electric power，and energy industries。Its IP67 protection rating and Ex d IIC T6 explosion-proof certification make it the preferred equipment in the field of high-risk gas monitoring。According to the 2023 Q3 industry report，affected by the global chip shortage，the delivery lead time of KYB-C3 has been extended to 8-12 weeks，and spot inventory is less than 15% of the total demand。

II、Technical Comparative Analysis of Three Major Alternative Solutions

III、Guide to Key Indicators for Procurement Decisions

Business evaluation personnel should focus on the following parameters：1) Long-term stability indicator（recommended to select <1%FS/year）；2) Media compatibility（316L stainless steel diaphragm is suitable for corrosive media）；3) Output signal type（4-20mA+HART protocol is more conducive to system integration）。According to the ASME B40.7 standard，it is recommended to reserve a 20% measuring range margin during model selection，and the engineering team of Xi'an Shenghongchuang can provide free technical matching services。

IV、Success Case：Implementation of an Alternative Solution for an LNG Project

In June 2023，we provided an SDP-SDP6400 alternative solution for a liquefied natural gas project in Northwest China。This model still maintains ±0.1% measurement accuracy in a -50℃ low-temperature environment and has passed SIL2 safety certification。A total of 87 KYB-C3 units were replaced in the project，reducing overall procurement costs by 15% and shortening the delivery lead time to 3 weeks。Customer feedback indicated that the new equipment performed better in pulsating pressure measurement scenarios，with vibration error reduced by 40%。
