Compact Pressure Transmitter
2025-09-17
Compact pressure transmitters offer multiple advantages in selection and application. The following is an explanation from two aspects: application advantages and selection key points:
I. Application Advantages
Compact Size & Flexible Installation: With a compact structure, it is suitable for installation in space-constrained scenarios (such as dense pipeline areas, inside equipment), saving installation space. It also supports multiple installation methods (threaded, flange, etc.).
High Measurement Accuracy & Stability: Equipped with a high-precision sensor, it can accurately measure pressure parameters (such as absolute pressure, gauge pressure, differential pressure). It is less affected by environmental interferences like temperature and vibration, resulting in small long-term use errors.
Wide Application Range: It can measure various media including liquids, gases, and steam, with a wide range of measurement ranges (from negative pressure to high pressure), meeting the needs of different fields such as industrial production, environmental protection, and medical care.
Convenient Signal Transmission: It usually outputs standard electrical signals (e.g., 4-20mA, 0-5V), which facilitates connection with control systems such as PLC (Programmable Logic Controller) and DCS (Distributed Control System), enabling remote monitoring and automatic control.
Strong Protection Performance: Some models have protection ratings for water resistance, dust resistance, and corrosion resistance (e.g., IP65/IP68), allowing stable operation in harsh environments (humid, dusty, corrosive media).
II. Selection Key Points
Measuring Medium & Environment: Based on the medium characteristics (corrosiveness, viscosity, temperature, etc.), select appropriate materials (e.g., 316L stainless steel, Hastelloy) and protection ratings. Consider environmental factors such as temperature, humidity, and vibration, and choose models with strong weather resistance.
Measurement Range & Accuracy: Determine the measurement range according to actual measurement needs (a margin of about 20% should be reserved). The accuracy class is usually above Class 0.5, and Class 0.1 can be selected for high-precision scenarios (e.g., laboratories).
Output Signal Type: Select the signal type based on the back-end interface. The commonly used ones are 4-20mA current signals (with anti-interference performance) or RS485 digital signals (suitable for long-distance transmission).
Installation Method: Choose threaded connection (e.g., G1/2, M20*1.5), flange connection, or clamp-type installation according to the on-site pipeline and equipment structure, ensuring firm installation and easy maintenance.
III. Typical Application Scenarios
HVAC Systems: Monitor pipeline pressure, requiring low power consumption and small size.
Medical Equipment: Demanding high precision and biocompatible materials.
Mobile Hydraulics: Featuring anti-vibration and anti-shock design.
By comprehensively evaluating the medium, environment, signal requirements, and budget, the most suitable compact pressure transmitter can be selected.
