As a core technology in the field of flow control equipment, the ZFBY-ZFBY3801 pressure transmitter adopts advanced diffused silicon sensor principles to accurately measure liquid and gas pressure. This article provides an in-depth analysis of the working principle of diffused silicon sensors, and compares the performance characteristics, calibration methods, and common troubleshooting of different pressure transmitter models such as the PTS series and TMS series, helping information researchers gain a comprehensive understanding of this key technology.

Working Principle and Core Technology of Diffused Silicon Sensors

As one of the mainstream technologies in modern pressure measurement, the core of diffused silicon sensors lies in utilizing the piezoresistive effect of silicon materials. When pressure acts on the silicon diaphragm, the diaphragm undergoes slight deformation, causing the resistance value of the embedded Wheatstone bridge to change, thereby outputting an electrical signal proportional to the pressure. The ZFBY-ZFBY3801 pressure transmitter uses a high-precision diffused silicon chip, and through temperature compensation and signal conditioning circuits, amplifies the weak electrical signal and converts it into a standard industrial signal (such as 4-20mA or 0-10V), achieving high-precision measurement of liquid and gas pressure. Compared with traditional sensors, diffused silicon technology offers significant advantages such as high sensitivity, good stability, and fast response speed.

Comparative Analysis of Mainstream Pressure Transmitter Models

There are many common diffused silicon pressure transmitter models on the market, each with different performance. The PTS-PTS504 pressure transmitter is known for its high cost performance and is suitable for general industrial applications; the PTS-PTS503 performs outstandingly in the medium- and high-pressure measurement field; while the ZFBY-ZFBY3801 has become the preferred choice in the process industry due to its excellent long-term stability. In terms of accuracy grade, the YH-A pressure transmitter can achieve 0.1%FS, meeting laboratory-grade requirements; the TMS-QY110 is specially designed for harsh environments, with a protection rating up to IP68. During selection, factors such as measured medium, pressure range, accuracy requirements, and environmental conditions should be comprehensively considered to ensure optimal equipment performance.

Key Points for Pressure Transmitter Calibration and Maintenance

Correct calibration is the key to ensuring the measurement accuracy of pressure transmitters. Calibration of the PTS-PTS502 pressure transmitter usually requires a standard pressure source and a precision ammeter, with calibration carried out in the sequence of zero point-full scale-midpoint. Common faults, such as abnormal display of the BP-IN pressure transmitter, are mostly caused by power supply fluctuations or medium crystallization, and can be resolved by checking the supply voltage and flushing the measuring chamber. Routine maintenance should include regular inspection of the integrity of sealing components and avoidance of overload use. It is worth noting that the domestic weighing sensor Model8511 corrugated tube weighing force sensor spring press sensor, although applied in different fields, also reflects the progress of domestic sensor technology through its alloy steel material and high accuracy of ±0.02%.

Industry Applications and Selection Guide

In the petrochemical industry, the TMS-GH186 pressure transmitter has become a safe choice for hazardous areas thanks to its explosion-proof design; the AO-X model has obvious advantages in equipment inspection because of its digital display function. For pipeline systems requiring multi-point monitoring, it is recommended to select intelligent transmitters with the HART protocol. During procurement, in addition to paying attention to the initial price (such as the price of the PTS-PTS501 pressure transmitter diffused silicon liquid gas pressure sensor), the total life cycle cost should also be evaluated, including indicators such as energy consumption, maintenance frequency, and calibration cycle.
