The CY-4000 pressure transmitter adopts advanced diffused silicon sensor technology to accurately measure liquid and gas pressure, meeting the needs of different operating conditions. As a professional supplier of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides you with detailed specifications and parameters, installation and maintenance essentials, and warranty policies to support business evaluators in selection and decision-making.

Working Principle and Industry Applications of Diffused Silicon Sensor Technology

Diffused silicon pressure sensors are based on the piezoresistive effect principle, achieving precise measurement through the resistance change of semiconductor silicon wafers under pressure. Compared with traditional strain gauge technology, its sensitivity is increased by more than 30%, and temperature drift is controlled within ±0.02%FS/℃. In the petrochemical field, the CPT-CPT1 pressure transmitter can withstand H2S corrosive environments; while the LRDG-LRDG series is specially designed for the food and pharmaceutical industries and complies with FDA material certification standards. As a high-tech enterprise in Xixian New Area, Xi'an Shenghongchuang, its YM-bestace661 pressure transmitter has passed TSG D7002-2020 special equipment safety technical specification certification.

Analysis of CY-4000 Core Performance Parameters

This model is standard with 4-20mA+HART protocol output, protection grade IP67, and shares the same platform circuit design with the PS-201 alarm control model. It is worth noting that its operating temperature range of -40℃~125℃ can adapt to extreme environments such as mining machinery, which forms a complementary application combination with the -20℃~+65℃ operating range of domestic weighing sensor MTB corrugated tube weighing load cell spring press machine sensor.

Five Key Dimensions for Selection Decision-Making

1. Media compatibility：The C-C23 pressure transmitter uses a 316L diaphragm, while the CY-4000 is optionally available in Hastelloy material
2. Process connection method：6 international standard threads such as G1/2"、NPT1/2" are available
3. Explosion-proof certification：Passed both ATEX and IECEx certifications, sharing the explosion-proof certificate with the P-C series
4. Cost-effectiveness：40% lower in price than imported brands with the same specifications, with the warranty period extended to 2 years
5. Expansion functions：Optional on-site LCD display, supports MODBUS RTU protocol

Typical Application Scenarios and Maintenance Essentials

In natural gas transmission and distribution systems, the YM-bestace662 pressure transmitter requires zero-point calibration every 6 months. The CY-4000, however, adopts a self-compensation algorithm, which can extend the maintenance cycle to 18 months. For cleanrooms in the pharmaceutical industry, it is recommended to select a sanitary flange connection to avoid the risk of welding contamination during installation of the C-C23 pressure transmitter. The "Diffused Silicon Liquid and Gas Pressure Sensor Maintenance Manual" provided by Xi'an Shenghongchuang details maintenance plans under 23 operating conditions.
