Professional Procurement Guide for Diffused Silicon Pressure Transmitters

As a professional procurement specialist，are you looking for the latest quotation for the DG1300-BZ-B-2-70/CJ/AM pressure transmitter？Xi'an Shenghongchuang provides you with professional solutions for diffused silicon liquid and gas pressure sensors。This article will introduce in detail the price ranges，performance features and procurement tips of KYB-C3，SDP-SDP6400 and other series products，helping you make informed purchasing decisions。

1、Analysis of Core Features of the DG1300-BZ-B-2-70/CJ/AM Pressure Transmitter

The DG1300-BZ-B-2-70/CJ/AM model is a typical representative of industrial-grade diffused silicon pressure transmitters，using the monocrystalline silicon piezoresistive effect principle，with measurement accuracy up to ±0.1%FS。Its stainless steel isolation diaphragm design is compatible with various media such as water，oil and gas，with an operating temperature range of -40℃~125℃。This model is specially equipped with lightning surge protection circuitry and radio frequency interference protection，making it suitable for harsh environments such as petroleum and chemical industries。

According to 2023 industry quotation data，the market reference price of the DG1300-BZ-B-2-70/CJ/AM pressure transmitter is in the range of RMB 2800-4500，and the specific price is affected by factors such as purchase quantity and certification requirements（such as explosion-proof certification）。Bulk purchases（50 units or more）can usually enjoy a discount of 12-15%。

2、Comparison of Technical Advantages of KYB-C3 Series Products

The KYB-C3 pressure transmitter adopts third-generation diffused silicon sensing technology，with notable features including：

• Zero stability better than 0.05%/year，with extremely low long-term drift
• Standard 4-20mA+HART protocol output，compatible with the vast majority of control systems
• IP67 protection rating，with SIL2 functional safety certification
• Measuring range covers 0-1kPa to 0-60MPa，meeting different pressure measurement requirements

This series of products is particularly suitable for hydraulic systems，compressed air monitoring and other applications。Depending on the configuration（such as whether it includes an LCD display，special interfaces，etc.），the price of the KYB-C3 pressure transmitter ranges from RMB 3200-6800。Compared with traditional capacitive transmitters，its media compatibility and overload resistance are improved by more than 40%。

3、Purchasing Guide for SDP-SDP6400 and CTX Series

The SDP-SDP6400 series adopts a unique temperature compensation algorithm，with temperature error not exceeding 0.5%FS within the range of -20℃~80℃。Its compact design（diameter only 44mm）is especially suitable for installation scenarios with limited space，with typical applications including：

The CTX-CTX series focuses on high cost performance，using a fully welded structure to ensure sealing performance。The basic model starts at only RMB 1850，making it an ideal choice for projects with limited budgets。Its advantages include 5-point linear calibration，reverse polarity protection and a 3-year warranty commitment。

4、5 Key Considerations for Professional Procurement

1.Media Compatibility Verification：Confirm whether the sensor material（such as ceramic/stainless steel）can withstand the measured medium。Acidic media require specially treated diaphragms

2.Balance Between Accuracy and Stability：For process control applications，it is recommended to select accuracy of 0.2% or higher，while inventory monitoring can be relaxed to 0.5%

3.Certification Requirements：Explosion-proof locations require ATEX/IECEx certification，and the food industry requires FDA/3-A certified materials

4.Output Signal Matching：Traditional DCS systems mostly use 4-20mA，while new projects are recommended to choose HART or PROFIBUS-PA protocols with digital communication

5.Lifecycle Cost：Including calibration cycle（usually 1-2 years），spare parts availability（standardized products are recommended）and maintenance convenience
