Importance of Maintenance for Diffused Silicon Pressure Transmitters

As a key device in industrial automation control, the maintenance of the core diffused silicon sensor in the PT-B pressure transmitter directly affects measurement accuracy and service life. This article, written by the expert team of Xi'an Shenghongchuang Instrumentation Co., Ltd., provides a detailed explanation of 7 major maintenance points for TS-TS201, TS-TS204 and other series of diffused silicon pressure transmitters, including routine cleaning, regular calibration, and environmental adaptation, helping you extend sensor service life by more than 30%.

Diffused silicon pressure sensors are widely used in petrochemical, environmental protection, electric power and other industries due to their advantages of high sensitivity and good stability. However, factors such as medium corrosion and mechanical vibration in harsh working environments will accelerate sensor performance degradation. Taking hydraulic control systems as an example, an uncalibrated TS-TS203 pressure transmitter may produce a measurement error of more than 0.5%, directly affecting production safety.

Seven Core Maintenance Points

1. Routine Cleaning and Protection

It is recommended to use anhydrous ethanol every week to wipe the probe surface of the PTB-PTB505 pressure transmitter to avoid pressure port blockage caused by medium crystallization. For equipment measuring viscous media, the flush diaphragm structure of the domestic flush diaphragm pressure transmitter PRC-908A can be selected, and its 316 stainless steel material can effectively prevent scaling. Special attention should be paid to:

• Do not use hard objects such as steel brushes to clean sensitive diaphragms
• Protective sleeves should be installed in corrosive environments
• Regularly check the sealing performance at cable connections

2. Periodic Calibration Specifications

According to ISO 9001 standards, equipment such as the TS-TS204 pressure transmitter should undergo zero/span calibration every 6 months. When using a standard pressure source, note:

3. Environmental Adaptability Optimization

For the application of the LPB-LPB8400 pressure transmitter in extreme temperature environments, it is recommended to:

1. Install a heat sink when the ambient temperature exceeds 85℃
2. Use heating tape for insulation under working conditions below -30℃
3. Select IP67 protection grade for places with humidity >95%

Key Technical Measures for Extending Service Life

4. Electrical System Protection

For devices with remote transmission signals such as the 7MF-MF1564 pressure transmitter, special attention should be paid to:

• Control power supply fluctuation within a range of ±10%
• Signal lines should be laid separately in metal conduits
• Install surge protectors in lightning-prone areas

5. Mechanical Stress Elimination

Pipeline vibration may cause microcracks in the diffused silicon chip of the NPT-NPT102 pressure transmitter. It is recommended to:

1. Install far away from vibration sources such as pumps and valves
2. Use flexible connecting pipes to buffer vibration
3. Regularly check the tightness of threaded connections

Solutions for Special Working Conditions

6. Corrosive Medium Handling

For the 7MF-MF1567 pressure transmitter used to measure acid and alkali media, it is recommended to adopt:

• Special customization of Hastelloy diaphragm
• Use pH test paper every month to detect medium changes
• Front-end chemical isolator solution

7. Pulsation Pressure Protection

Pressure shocks in hydraulic systems may damage the sensor of the PT-B pressure transmitter. The following measures can be taken:

1. Install a pulsation damper
2. Set software filtering parameters
3. Select the PRC-908A transmitter with 300% overload capacity

Summary and Professional Recommendations

By implementing the above 7 maintenance strategies, the reliability of diffused silicon liquid and gas pressure sensors can be significantly improved. Data from Xi'an Shenghongchuang Instrumentation shows that the average service life of the TS-TS201 transmitter with alarm control under standardized maintenance reaches more than 8 years. For special working condition requirements, we provide customized solutions for the full series including the 7MF-MF1566 pressure transmitter.
