Analysis of the Three Operating Modes and Core Advantages of pressure scanners

In today's industrial measurement field, pressure scanners have become key equipment for high-precision, multi-channel pressure data acquisition. Faced with numerous products and brands on the market, choosing a pressure scanner and supplier with superior performance and reliable cooperation has become a focus for many users.

Pressure parameter measurement is ubiquitous, both in daily life and industrial manufacturing. Compared to conventional pressure gauges or single pressure sensors, pressure scanners are essentially pressure measuring instruments, but their core value lies in their ability to simultaneously acquire pressure data from dozens or even hundreds of measuring points, significantly improving the efficiency of pressure acquisition. Depending on the measured medium, pressure scanners can be divided into gas type and liquid type, further expanding their application range.

Currently, most pressure scanner products on the market are designed for gaseous media by default, with sampling rates generally limited to 500Hz or 1000Hz. While this can meet general application scenarios, it often struggles to accurately capture instantaneous pressure fluctuations in complex scenarios with high-frequency changes. To address this sampling bottleneck, KETU&TEST has continuously increased its R&D efforts, achieving a significant leap in the sampling rate of its entire series of scanning valves, reaching an adjustable rate of 0–10kHz, fully meeting the needs of high-frequency measurements. As a professional enterprise in the field of pressure and temperature measurement, KETU&TEST’s pressure measurement products are divided into gas pressure scanners and liquid pressure scanners, and are also compatible with various measurement methods such as gauge pressure, absolute pressure, and differential pressure. They integrate three working modes: measurement, purging, and calibration, making them an ideal choice for pressure measurement applications. The three working modes—measurement, purging, and calibration—significantly enhance the functionality of the pressure scanner and are key parameters that differentiate it from other pressure scanner products on the market. The following is a detailed introduction to these three working modes:

Measurement Mode: The pressure scanner performs routine pressure data acquisition tasks, recording pressure data from monitoring points in real time in conjunction with KetuSoft acquisition software. The pressure scanners of KETU&TEST achieve a maximum measurement accuracy of ±0.05%FS, with an adjustable sampling rate of 0-10kHz. All channels achieve synchronous acquisition, and devices can be expanded through a switch connection. It possesses excellent anti-interference capabilities and can handle most complex measurement scenarios.

Purge Mode: By switching to purge mode via a dedicated push valve interface, air is blown in reverse into the valve body's internal channels, effectively removing accumulated impurities and dust. Most products on the market lack this function, making pressure scanners with a purge calibration mode more competitive. KETU's pressure scanners have a purge pressure ≥0.7MPa, demonstrating excellent advantages in harsh working conditions or highly polluted environments. Furthermore, regular purging ensures long-term stable operation.

Calibration Mode: All channels of the pressure scanner are simultaneously calibrated in one go using an external standard pressure source. As a high-precision instrument, pressure scanners may experience data drift during long-term use, making regular calibration essential. KETU's pressure scanners support simultaneous calibration of all channels, ensuring long-term accuracy and reliability.

In conclusion, when selecting a pressure scanner, it is crucial to consider not only its basic parameters but also its sampling rate and the completeness of its operating modes, and to thoroughly examine the manufacturer's reliability and technical support capabilities. KETU&TEST provides not only a high-performance product, but also a reliable partner, helping users achieve more accurate and efficient data acquisition in scientific research and industrial applications.
