The Key Role of Diffused Silicon Sensors in YM-115 Pressure Transmitters

As the core component of the YM-115 pressure transmitter, the stability of the diffused silicon sensor directly affects the accuracy of industrial flow control. This article focuses on 5 common types of diffused silicon sensor faults in YM-115 pressure transmitters, including calibration abnormalities in the YSZK-01G-C model and display faults in the DMK331-250-4000, providing professional solutions to help technical evaluators quickly diagnose issues and restore optimal equipment performance.

1. Calibration Abnormalities in YSZK-01G-C Pressure Transmitters and Solutions

During use, the YSZK-01G-C pressure transmitter may experience calibration abnormalities, mainly manifested as output signals that do not match the actual pressure value. These problems are usually caused by the following reasons:

• Sensor zero drift
• Temperature compensation failure
• Unstable supply voltage

Solution: First, check whether the power supply is stable, and it is recommended to use a regulated power supply. Second, perform zero calibration and full-scale calibration according to the manual. If the problem still exists, the sensor chip may need to be replaced.

2. Troubleshooting Display Faults in DMK331-250-4000 Pressure Transmitters

Common display faults in the DMK331-250-4000 pressure transmitter include no display, fluctuating display values, or display error codes. These problems may be caused by:

• Poor display module connection
• Main control board failure
• Abnormal sensor signal

Solution: First, check whether the wiring of the display module is loose or oxidized. Second, measure whether the sensor output signal is normal. If the display module is damaged, it is recommended to replace it with a new one.

3. Calibration Method for YMP-YMP489 Pressure Transmitters

Calibration of the YMP-YMP489 pressure transmitter is a key step in ensuring measurement accuracy. The correct calibration procedure includes:

1. Prepare a standard pressure source
2. Connect the calibration equipment
3. Perform zero calibration
4. Perform full-scale calibration
5. Verify the calibration results

It should be noted that the ambient temperature for calibration should be maintained at 20±5℃, and the humidity should not exceed 85%RH. After calibration is completed, it is recommended to conduct at least 3 repeatability tests to ensure the reliability of the calibration results.

4. Common Types and Applications of YM-1KGR Pressure Transmitters

According to different measuring media, YM-1KGR pressure transmitters are mainly divided into the following types:

Choosing the appropriate model is crucial for ensuring measurement accuracy and equipment service life. It is recommended to select a suitable model based on actual operating conditions.

5. Diagnosis and Handling of Display Abnormalities in MBS-G3131 Pressure Transmitters

Display abnormalities in the MBS-G3131 pressure transmitter may be manifested in the following situations:

• The displayed value remains fixed
• The displayed value jumps randomly
• The displayed value exceeds the range

Diagnostic steps: First, check whether the power supply voltage is within the rated range; second, check whether the sensor connection is good; finally, check whether the sensor itself is damaged. Handling solutions include recalibration, replacing the connection wire, or replacing the sensor.
