In the field of industrial automation, the cost-performance ratio of the PTS-PTS503 pressure transmitter is key to procurement decisions. This article provides an in-depth analysis of price comparisons for diffused silicon liquid and gas pressure sensors, helping information researchers understand the price differences and core parameters of models such as PTS-PTS504 and TMS-QY110, so you can choose the most suitable industrial-grade pressure sensing solution.

Technical Performance and Market Positioning of Diffused Silicon Sensors

Diffused silicon pressure sensors have become a mainstream choice for industrial measurement due to their outstanding stability and accuracy. Taking the domestic industrial 2088 pressure transmitter TV920 digital display diffused silicon 2088 pressure sensor as an example, it uses 316 stainless steel, covers a measurement range of 0～250MPa, and can achieve an accuracy of 0.25 class, making it perfectly suited for demanding scenarios such as hydraulic control and petrochemicals. Compared with traditional strain gauge sensors, diffused silicon technology offers better temperature drift performance（≤±0.05％FS／℃）, which explains why models such as PTS-PTS504 are highly favored in high-temperature environments such as power station inspections.

Comparative Analysis of Mainstream Model Pricing

The comparison shows that the accuracy class directly determines the price tier. For projects with limited budgets but requiring long-term stable operation, the TV920 series demonstrates extremely high cost performance among 0.25 class sensors, and its annual stability parameter of ±0.1%FS is even better than that of some imported brands. It is worth noting that although economical products such as BP-IN have lower unit prices（about 600-900 yuan）, their failure rates may increase subsequent maintenance costs.

Analysis of Core Selection Parameters

Information researchers should focus on three key technical indicators: first is media compatibility, as 316 stainless steel can resist corrosive media in the petrochemical field; second is the temperature compensation range, and TV920's 0～70℃ compensation ensures data reliability in scenarios with sharp temperature differences such as vehicle braking; finally is the output signal type, where two-wire 4～20mA output is more suitable for long-distance transmission, while three-wire 0～10VDC is suitable for workshop environments with dense equipment.

In-Depth Matching of Industry Application Scenarios

In the environmental protection field, ZFBY-ZFBY3801 has become the preferred choice for wastewater treatment thanks to its IP67 protection rating; while oil pipeline monitoring requires explosion-proof certified products such as YH-A. Especially in constant-pressure water supply systems, diffused silicon sensors need to have a fast response characteristic of ≤5 milliseconds, which is exactly one of the core advantages of the TV920 pressure transmitter, and its matching compact LCD display module also enables on-site real-time monitoring.

Common Selection Misconceptions FAQ

Q：Is a higher accuracy class always better?
A：Not necessarily. For example, building automation control can meet requirements with the 1.0 class TMS-GH186, and blindly pursuing 0.25 class would cause more than 30% cost waste.
Q：How to determine whether a diffused silicon sensor needs temperature compensation?
A：When the ambient temperature fluctuation exceeds 20℃ or the medium temperature exceeds the range of -30～+85℃, a model with temperature compensation must be selected.
Q：Can domestic sensors replace imported brands?
A：Taking TV920 as an example, its stability of ±0.1%FS/year has already reached the international first-class level, and its price is only 60% of imported products of the same specification.
