As a core device in industrial flow control, the installation and commissioning of the AC-P1 pressure transmitter directly affect measurement accuracy and equipment service life. This article focuses on 5 common installation misconceptions for similar products such as PT1661 and STZ7, and combines the professional technical experience of Xi'an Shenghongchuang Instrumentation to provide practical avoidance solutions for technical evaluation personnel, helping achieve optimal equipment performance.

I. Industry Background and Market Analysis of Pressure Transmitters

With the improvement of industrial automation levels, pressure transmitters are being increasingly widely used in petrochemical, electric power, water treatment, and other fields. According to market research data, the global pressure transmitter market size exceeded 5 billion USD in 2023, among which the annual growth rate of the Chinese market remained above 8%. As key components of flow control equipment, pressure transmitters such as AC-P1 and PT1661 are widely favored for their high accuracy and stability. However, in practical applications, about 35% of equipment failures originate from improper installation and commissioning, which not only increases maintenance costs but may also cause safety hazards.

II. 5 Common Errors in the Installation and Commissioning of the AC-P1 Pressure Transmitter

1. Improper Selection of Installation Location

Many technical evaluation personnel overlook the impact of the pressure transmitter's installation location on measurement accuracy. For example, installing AC-P1 near a pump with strong vibration, or close to a high-temperature heat source, will cause sensor signal drift. The correct approach is to choose an area away from mechanical vibration and sudden temperature changes, and ensure the mounting bracket is secure. For the PT1661 pressure transmitter, it is also necessary to consider the relationship between medium flow direction and installation angle to avoid bubble accumulation affecting readings.

2. Non-standard Sealing Treatment

Poor sealing is a common cause of leakage in pressure transmitters such as STZ7. Using mismatched sealing gaskets or failing to tighten bolts according to torque requirements may both lead to medium leakage. Engineers at Xi'an Shenghongchuang Instrumentation recommend using sealing components made of 316L stainless steel, and performing airtightness testing according to the ISO 5208 standard to ensure no leakage under 1.5 times the working pressure.

3. Electrical Connection Errors

Incorrect wiring of the CFBTD pressure transmitter may lead to signal interference or even equipment damage. Typical problems include not using shielded cables and improper grounding wire connections. The solution is to strictly follow the IEC 61010-1 electrical safety standard, use twisted-pair shielded cables, and control grounding resistance below 4Ω. For digital transmitters such as DY20X, attention should also be paid to the polarity matching of the RS485 communication line.

4. Inaccurate Range Calibration

About 28% of HAKK-316 pressure transmitters show measurement deviation in the early stage of use, which is often related to improper calibration methods. Technical evaluation personnel should note: before calibration, preheat the equipment for 30 minutes, use a standard pressure source with an accuracy grade 3 times higher than that of the transmitter, and perform linear calibration at five points: 0%, 25%, 50%, 75%, and 100%. For high-temperature transmitters such as STZ2, temperature compensation calibration is also required.

5. Lack of Protective Measures

In corrosive environments, the diaphragm of the CFBPK/B pressure transmitter may be rapidly damaged due to the absence of a protective isolator. For applications in the chemical industry, it is recommended to select models with a Hastelloy diaphragm and install a capillary isolation system. Cases from Xi'an Shenghongchuang show that after adopting these measures, the average service life of the equipment was extended by 40%.
