ET-A Pressure Transmitter Customization，Meeting Your Personalized Needs

In the field of industrial automation，the customized service for ET-A pressure transmitters provides professional solutions for your special requirements。Whether it is the maintenance of LD-LD183，or the alarm control function of PS-201，diffused silicon liquid and gas pressure sensors can be precisely adapted。We provide comprehensive services from PN-M2 remote transmission signals to YBS-S100 calibration，ensuring efficient and stable operation of your system。

I、Core Advantages and Technical Analysis of Diffused Silicon Pressure Transmitters

As the gold standard in the field of pressure sensing，diffused silicon technology is based on the piezoresistive effect of monocrystalline silicon materials。Taking the ET-A series as an example，a Wheatstone bridge is formed on the surface of the silicon diaphragm through semiconductor processing，and when pressure is applied，changes in resistance generate millivolt-level signals。Compared with traditional strain gauge technology，diffused silicon sensors feature high accuracy of 0.1%FS and annual stability of ±0.5%，making them especially suitable for long-term monitoring of corrosive media in chemical processes。Our customization service can be configured with 4-20mA+HART protocol output for remote transmission requirements of models such as PN-M2，solving the problem of signal attenuation。

III、Five Key Points for Operation and Maintenance

1. LD-LD183 Routine Maintenance：Check the condition of the sealing ring monthly，and Hastelloy diaphragms are recommended for highly corrosive environments
2. PCM-D Installation Specifications：Avoid installation within 3 meters of vibration sources，and PTFE sealing tape is required for threaded connections
3. MBC-1 Fault Diagnosis：When the output signal fluctuates，first check whether the pressure guide tube is blocked
4. CEQ-CEQ1300 Media Adaptation
5. HB-S Explosion-Proof Certification：In Zone1 areas，versions with ATEX certification must be selected

IV、Solutions to Industry Pain Points

To meet the GMP certification requirements of the pharmaceutical industry，we have developed a hygienic structure for the ET-A series，meeting the 3D surface roughness standard of Ra≤0.8μm。A bioreactor project case shows that the customized quick-install clamp connection reduced sensor replacement time from 2 hours to 15 minutes。For the PS-201 alarm control model，the unique dual-redundant circuit design prevents batch scrapping caused by false triggering，helping customers save more than 200,000 yuan in annual maintenance costs。

V、Frequently Asked Technical Questions

• Q：How to choose between diffused silicon and ceramic sensors？
  A：Ceramic sensors are suitable for media containing particles such as slurry，but diffused silicon provides better temperature characteristics within the range of -40~125℃
• Q：What should be done if the remote transmission signal is interfered with？
  A：The PN-M2 model can be equipped with an optional signal isolator，effectively suppressing common-mode interference caused by frequency converters
• Q：How to verify the validity of YBS-S100 calibration？
  A：Three-point calibration is recommended every 6 months，using a standard instrument with accuracy 3 times higher than that of the sensor under test
