As a professional solution provider in the field of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides you with efficient and precise installation guidance. Whether it is the PT-A, CYB-28, or TS-802 series, we can help you easily master wiring techniques to ensure measurement accuracy and service life.

I. Technical Principles and Industry Background of Diffused Silicon Pressure Sensors

As a core component of modern industrial measurement, the working principle of the diffused silicon pressure sensor is based on the semiconductor piezoresistive effect. When pressure is applied to the silicon diaphragm, the resistance value of the Wheatstone bridge changes, and the signal is converted into a standard current/voltage output through the SWT-SWT131 pressure transmitter. In scenarios such as petrochemicals and power energy, the accuracy of models such as CYB-23 and MT-A can reach ±0.1%FS, meeting ISO 9001 and CE certification requirements. It is worth noting that the domestic displacement sensor TD-1-350 differential pull-rod linear displacement sensor spring-return inductive sensor also adopts a similar precision conversion principle, demonstrating outstanding performance in the field of mechanical measurement.

II. Step-by-Step Analysis of the SWT-SWT131 Wiring Diagram

1. Power wiring: the red lead is connected to the positive pole of 24VDC, and the black lead is connected to the negative pole; shielded cables should be used to reduce interference.2. Signal output: the green wire corresponds to the 4-20mA output terminal, and the white wire is the signal ground.3. Special configuration: the supporting equipment of QYB-QYB101 needs to be grounded separately. When used together with FG-FG500 original accessories, the grounding resistance should be less than 4Ω. Common misunderstandings include laying the RS485 communication line of the PLS-PLS supporting instrument parallel to the power line, which will cause signal attenuation of up to 30%.

III. Key Points for Installation and Commissioning

1. Medium compatibility: the measurement range of CYB-28 needs to match the medium characteristics, and corrosive liquids should use a 316L diaphragm.2. Environmental adaptability: TS-802 needs to be equipped with a heat sink in environments of -40~85℃, and in vibration scenarios it is recommended to use the SNYB-SNYB810 anti-vibration bracket.3. Calibration process: the PT-A pressure transmitter requires zero-point calibration every 6 months. Use a standard pressure source to calibrate 5 range points point by point, and if the error exceeds 0.5%, it needs to be returned to the factory for repair.
