Wired Pressure Transmitter with 4-20mA Analog Sensor
Clouds Wired Pressure Transmitter is an industrial instrument that combines high-precision pressure sensing technology with stable wired signal output. Through high-quality sensors and circuit processing, it converts detected pressure signals into standard 4-20mA current signals or RS485 digital signals (such as Modbus-RTU protocol), transmitting them directly via cable to control systems or display devices.
Typically featuring a stainless steel housing and rugged design, the product offers excellent corrosion resistance and shockproof capabilities, making it suitable for harsh industrial environments such as high temperatures and humidity. Its battery-free operation with continuous power supply makes it particularly well-suited for fixed installations requiring 24/7 continuous monitoring where power access is readily available.
Description
Product Advantages and Core Technology
Compared to wireless products, wired connections offer distinct advantages in certain scenarios. The table below clearly outlines the core strengths of this wired pressure transmitter:
1. Stable and Reliable Connection: Wired transmission (e.g., 4-20mA) exhibits strong interference resistance, delivering stable signals unaffected by network fluctuations or obstructions, ensuring continuous, uninterrupted data flow.
2. High Real-Time Performance: Signal transmission occurs without delay, supporting millisecond-level response times to meet the demands of real-time control systems requiring rapid feedback.
3. Simplified Installation and Commissioning: Direct wiring is straightforward for applications with existing cabling infrastructure or short-distance deployments, eliminating the need for complex wireless network parameter configuration.
4. No Battery Maintenance: Continuous power supply from an external source (e.g., DC24V) eliminates battery life concerns and reduces long-term maintenance workload.
5. Rugged Durability: Constructed from materials like stainless steel, offering excellent corrosion resistance and shockproofing for harsh industrial environments. Typically achieves IP65 or higher protection ratings.
6. High-Precision Measurement: Utilizes high-performance sensors and temperature compensation technology to deliver high-accuracy measurements (e.g., ±0.1%FS, ±0.5%FS) with long-term stability.
Application Areas
This wired pressure transmitter is widely used in industrial processes and equipment requiring stable, reliable, real-time continuous pressure monitoring:
✅ Industrial Process Control: Pressure monitoring and control for pipelines, reactors, compressors, and other equipment in petrochemical, power metallurgy, pharmaceutical, food, and other industries.
✅ Fluid System Monitoring: Pressure monitoring for water supply/drainage systems, thermal networks, hydraulic and pneumatic systems.
