As the core product of diffusion silicon sensors, the precise calibration of the TS-TS203 pressure transmitter directly affects the reliability of industrial flow control. This article, written by experts from Xi'an Shenghongchuang Instrumentation Co., Ltd., explains in detail the 8 key steps for calibrating diffusion silicon liquid and gas pressure sensors, helping engineers master the maintenance points of products in the same series such as PTB505 and TS-TS201, and improve the measurement accuracy of customized models such as 7MF-MF1567.

The Importance of Diffusion Silicon Sensor Calibration

In the field of industrial flow control, the accuracy of pressure transmitters is directly related to production safety and efficiency. Diffusion silicon sensors, due to their excellent stability and sensitivity, have become the core components of models such as TS-TS203 and PTB505. However, as usage time increases, sensor performance may drift. Data shows that for diffusion silicon sensors without regular calibration, the measurement error can reach as high as 2.5%FS, which will cause serious hidden dangers for industries such as chemicals and energy that require precise flow control. Through 10 years of industry practice, Xi'an Shenghongchuang Instrumentation Co., Ltd. has found that adopting a calibration process based on ISO/IEC 17025 standards can improve the long-term stability of models such as TS-TS204 by more than 60%.

Detailed Explanation of the 8 Key Steps for TS-TS203 Calibration

Step 1: Environmental Preconditioning. Place the TS-TS203 pressure transmitter in the calibration environment for at least 2 hours to ensure thermal equilibrium between the sensor and the medium. Diffusion silicon elements are temperature-sensitive, and it is recommended to use the domestic TK70 temperature transmitter for real-time monitoring, whose ±0.15℃ accuracy can meet the requirements of the GJB2244A-2011 standard.

Step 2: Zero-Point Calibration. Under no-pressure conditions, adjust the 4mA output point through a HART communicator. Special note: for models such as TS-TS201 with alarm control, the alarm threshold must also be calibrated simultaneously.

Step 3: Full-Scale Calibration. After applying the rated pressure, adjust the 20mA output point. For diffusion silicon sensors, it is recommended to use the stepwise pressurization method, with each pressurization not exceeding 25% of the range, which is consistent with the preloading principle in the PTB505 installation instructions.

Comparative Analysis of Industry Applications

In the petrochemical field, the explosion-proof design of TS-TS203 is superior to the basic LPB8400 model; while 7MF-MF1566 is more favored in the food and pharmaceutical industry because of its 316L stainless steel material. Customer cases of Xi'an Shenghongchuang show that the TS-TS204 remote transmission model using a customized calibration solution has reduced the annual failure rate in long-distance pipelines to 0.3 times/thousand units.

Common Misunderstandings and Professional Recommendations

Misunderstanding 1: Only performing two-point calibration. In practical applications, the linearity at intermediate range points is equally critical. We recommend performing at least 5-point verification for the PTB series.

Misunderstanding 2: Ignoring medium influence. Gas and liquid calibration require different methods, especially for small-range models such as 7MF-MF1564.
