PG-PG1300 Pressure Transmitter Selection Guide: Price and Performance Comparison of Diffused Silicon Sensors

When selecting a PG-PG1300 pressure transmitter, the price and performance of the diffused silicon sensor are often the two factors users care about most. As a professional flow control equipment manufacturer, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides you with a detailed analysis of the cost-performance ratio of different models of diffused silicon pressure transmitters, helping information researchers make informed choices.

I. Core Advantages of Diffused Silicon Pressure Transmitters

Diffused silicon sensors have become the preferred choice for industrial pressure measurement due to their high accuracy, long-term stability, and fast response characteristics. The PG-PG1300 series uses imported diffused silicon chips and is packaged through special processes, offering the following technical advantages:

• Measurement accuracy: up to ±0.1%FS, better than traditional strain gauge sensors
• Temperature compensation: built-in full-temperature-range compensation algorithm (-20℃~85℃)
• Media compatibility: 316L stainless steel isolation diaphragm can measure corrosive liquids/gases
• Output signal: standard 4-20mA analog output, optional RS485 digital interface

Compared with similar products such as SC-SC316 and HQ-HQ316, PG-PG1300 performs better in long-term drift indicators, with annual stability <0.2%FS, making it especially suitable for process industry scenarios that require continuous operation.

II. Comparative Analysis of Mainstream Model Prices

Price differences mainly come from material processes (for example, PTD-PTD502 uses a flange connection with higher cost), certification levels (for example, FR-YL2 has passed SIL2 certification), and additional functions (for example, PA-G comes with an on-site LCD display). It is recommended to choose according to actual working conditions to avoid paying for unnecessary functions.

III. Interpretation of Key Performance Indicators

1. Accuracy grade comparison

Both PTD-PTD503 and PG-PG1300 claim ±0.1% accuracy, but actual tests show that under a 10MPa range, the linearity error of PG-PG1300 is 30% lower than the industry average, thanks to its unique temperature compensation algorithm.

2. Long-term stability test

We conducted a 2000-hour aging test on PTD-PTD504, and its zero-point drift was 0.15%FS, while PG-PG1300 was only 0.08%FS under the same conditions, proving the reliability advantage of diffused silicon sensors in long-term use.

3. Dynamic response speed

In rapid pressure fluctuation scenarios (such as hydraulic system impact testing), the response time of PG-PG1300 is <1ms, significantly better than the 5ms of PTD-PTD502, which is crucial for process control requiring real-time monitoring.

IV. Selection Recommendations and Procurement Guide

Based on 20 years of industry service experience, we recommend that information researchers focus on the following dimensions:

1. Media characteristics: for corrosive media, choose the PTD-PTD504 series with a Hastelloy diaphragm
2. Ambient temperature: for high-temperature working conditions (>85℃), the FR-YL2 model with cooling fins should be selected
3. Installation method: for pipeline installation, PG-PG1300 with ZG1/2" thread is preferred, and for tank installation, the flange-type PTD-PTD501 is recommended
4. Certification requirements: hazardous areas such as petrochemical sites must use the ZF-S-X transmitter with ATEX certification

As the largest diffused silicon sensor manufacturer in Northwest China, Xi'an Shenghongchuang has all products certified under the ISO9001 quality management system and provides an ultra-long 3-year warranty. We recommend that users purchase through direct manufacturer sales channels (such as PTD-PTD501 direct from the manufacturer), which can save 15%-20% in intermediary costs.
