High-Precision Industrial Pressure Sensor for Reliable Process Monitoring & Control
Product Overview
Our pressure transmitters adopt high-performance sensing elements paired with precision signal conditioning circuits, converting on-site pressure physical quantities (gauge pressure, absolute pressure, differential pressure) into standard industrial electrical signals. They are designed to work seamlessly with PLC, DCS control systems and display instruments, delivering accurate real-time pressure data for industrial automation process control.
With excellent long-term stability, strong anti-interference capability and robust industrial-grade construction, they are widely deployed across industries for reliable pressure measurement, real-time monitoring and closed-loop regulation, serving as a core sensing component for stable process operation.
Core Features
-
High-Accuracy Measurement with Excellent Stability
Equipped with premium diffused silicon or ceramic capacitive sensing elements, paired with built-in digital temperature compensation and linear correction circuits, the transmitter achieves high measurement accuracy and minimal zero drift. It maintains consistent performance during long-term continuous operation, capturing subtle pressure fluctuations to support precise process control.
-
Wide Measuring Range & Flexible Pressure Types
Covers a broad measuring range from micro-pressure to ultra-high pressure, with optional gauge pressure, absolute pressure and differential pressure configurations. Customized range specifications are available to adapt to diverse detection demands for fluids, gases and steam, fully matching the working condition requirements of different process scenarios.
-
Industrial-Grade Robust & Corrosion-Resistant Build
All wetted parts adopt 304/316L stainless steel material, featuring excellent corrosion resistance and mechanical impact resistance. The field-mounted housing reaches IP65 protection grade as standard, effectively resisting dust, moisture and on-site vibration, ensuring reliable long-term service even in harsh industrial environments.
-
Diverse Output & Communication Compatibility
Supports multiple standard output signals including 4-20mA analog and RS485 digital (Modbus RTU protocol), with optional HART protocol for intelligent remote configuration and calibration. It can be seamlessly integrated into various control systems and upper monitoring platforms, effectively reducing system integration difficulty and cost.
-
Comprehensive Protection & Strong Anti-Interference
Built-in reverse polarity protection, over-voltage protection, over-current protection and surge protection effectively prevent device damage caused by wiring errors and abnormal grid conditions. The optimized circuit design delivers excellent electromagnetic compatibility, suppressing on-site interference from frequency conversion equipment and high-power devices, ensuring distortion-free signal transmission.
-
Standardized Design for Easy Installation & Maintenance
Adopts universal industrial process connections (threaded, flange, clamp types optional) for direct installation on pipelines, tanks and equipment. The compact modular structure and standardized dimensions support direct replacement of same-specification products, with no routine calibration required under normal use, greatly reducing on-site maintenance workload.
