Analysis of the Core Performance of Diffused Silicon Pressure Sensors

The GPD-GPD10 pressure transmitter adopts diffused silicon technology to realize pressure signal conversion through the semiconductor piezoresistive effect. In actual testing, its 0.25 class overall error accuracy can stably maintain a temperature drift performance of ±0.05%FS/℃, making it particularly suitable for dynamic pressure monitoring in hydraulic control systems. Compared with traditional strain gauge sensors, this model can still maintain excellent signal linearity within the medium temperature range of -30～+85℃.

It is worth noting that Domestic Industrial 2088 Pressure Transmitter OPT8250 Diffused Silicon 2088 Pressure Sensor also uses 316 stainless steel as the wetted material, demonstrating good compatibility in corrosive media measurement in the petrochemical industry. Both feature a fast response characteristic of ≤5 milliseconds, which is especially important for scenarios requiring real-time feedback such as power station inspections.

Measured Data from Typical Application Scenarios

Key Technical Points in Operation and Maintenance

Installation and Commissioning Specifications

Special attention should be paid to sealing treatment for the threaded installation of model PT124B-210-100MPa-M20:

• Use M20×1.5 standard threads with PTFE sealing tape
• Avoid mechanical overload impact exceeding 300MPa
• When using three-wire wiring, ensure that the 24V power supply fluctuation does not exceed ±5%

For CS-m series products, the built-in zero point ±8% adjustment function can effectively compensate for static pressure errors caused by the installation position. In building automation systems, it is recommended to work with a display meter to achieve on-site visual calibration.

Troubleshooting Guide

When signal drift occurs in the GT-V model, troubleshooting should be carried out according to the following steps:

1. Check whether the medium temperature exceeds the range of -30～+85℃
2. Measure whether the supply voltage is stable within the 9-36VDC range
3. Use a standard pressure source to recalibrate zero point/full scale

Horizontal Comparison of Mainstream Market Models

Comparison of JYB-KO-HAG and GPTJG-BSCHX in metallurgical industry applications:

• Response speed: HAG series 5ms vs BSCHX series 8ms
• Interface options: the former comes standard with G1/2 male thread, while the latter optionally offers M12×1
• Cost performance: PB-CNM1 can reduce costs by 15% in bulk procurement

Experimental data shows that Domestic Industrial 2088 Pressure Transmitter OPT8250 Diffused Silicon 2088 Pressure Sensor still performs 2 percentage points better in stability than imported similar products when measuring ultra-high pressure at 250MPa, thanks to its special temperature compensation algorithm.
