As a key device in industrial flow control, the correct installation of the PA-PA3010 pressure transmitter directly affects measurement accuracy and service life. This article focuses on the installation pain points that concern business decision-makers most, and provides a detailed analysis of 3 common incorrect operations, helping you avoid the risk of performance loss of diffusion silicon Hersman pressure sensors during the installation stage and ensuring stable operation of the equipment under harsh working conditions.

1. Mistake 1: Ignoring medium compatibility leads to corrosion risk

In scenarios such as petrochemical and metallurgy, about 38% of sensor failures are caused by mismatches between the medium and material. The PA-PA3010 uses a 316 stainless steel body, but if it comes into contact with strong acid media, a Hastelloy diaphragm must be selected. There was once a power company that failed to verify the chloride ion content, causing the flange sealing ring of the domestic capacitive pressure transmitter PI-3351 to be corroded through within three months, resulting in system shutdown losses. Decision-makers need to pay special attention: when the medium temperature exceeds 100℃, fluororubber seals must be selected.

2. Mistake 2: No damping adjustment in vibration environments

Mechanical vibration in scenarios such as pump rooms and compressors can cause measurement value fluctuations. Although the PA-PA3010 has an adjustable damping function of 0.2~32 seconds, 90% of users do not enable this feature. Comparative tests show that in a 200Hz vibration environment, the error without damping adjustment reaches ±0.3%, while after correct setting it can be controlled within ±0.05%. It is recommended to refer to the IEC801 standard and install anti-vibration brackets for vibration source equipment.

3. Mistake 3: Static pressure compensation not calibrated

During high-pressure pipeline installation, static pressure of 140kgf/cm² will cause the PA-PA3010 to generate a measurement range error of ±0.5%. Our case database shows that a chemical plant failed to perform static pressure compensation, resulting in a measurement deviation of 2.3% during the start-stop phase of the DBS-DBS316 pressure transmitter. The correct approach is to apply working pressure after installation and perform zero-point calibration through the HART protocol.

4. Why choose our solution

As a national high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd. has all diffusion silicon Hersman pressure sensors certified to IEC standards. We provide: ① free on-site installation guidance services; ② 40:1 ultra-wide turndown ratio design; ③ six-month ±0.15% stability guarantee. Compared with similar PI-3351 differential pressure transmitters, our PA-PA3010 has greater advantages in overload resistance and explosion-proof rating (Exia Ⅱ CT6).

Technical parameter comparison

• Temperature compensation:automatic compensation over the full range of -40~100℃ (industry average is only -20~80℃)
• Explosion-proof certification:simultaneously certified for both flameproof Exd and intrinsically safe Exia
• Volume change:0.16cm³ (37% lower than competing products)
