Overview

Based on the differential pressure sensing principle, it monitors the gas pressure difference inside the equipment and before and after the pipelines in real time, accurately reflecting operating conditions such as changes in air resistance, filter bag blockage, pipeline ash accumulation, and abnormal fan operation. It provides core data support for adjusting the cleaning frequency, providing early warning of filter bag blockage, troubleshooting duct faults, and controlling system air pressure. It can effectively avoid problems such as filter bag clogging, airflow reduction, fan overload, and pipeline ash blockage, making it a core gas monitoring instrument for stable, efficient, and intelligent control of dust removal and desulfurization systems.

Features

Employs an industrial-grade high-precision differential pressure sensor core, providing sensitive and accurate gas differential pressure detection with a fast response time. It can capture minute changes in wind pressure difference, updating data in real-time without lag or deviation. This provides accurate feedback on the air resistance conditions of the dust removal pipeline, offering reliable data for intelligent adjustment of the cleaning cycle.

Specifically designed for industrial gas conditions, it exhibits excellent resistance to dust and airflow impact, making it suitable for long-term operation in complex pipeline environments such as dusty flue gas, high-temperature airflow, and humid gases. The sensor probe is not prone to dust accumulation or corrosion, and its performance does not degrade, making it suitable for long-term continuous operation of dust removal and desulfurization systems.

Extremely stable operation, unaffected by pipeline airflow fluctuations, electromagnetic interference, or temperature and humidity changes. There is no data drift or numerical fluctuation, maintaining accurate and stable differential pressure data output under both high-volume dynamic conditions and low-load stable pressure conditions.

Equipped with a standard 4-20mA signal output, it can seamlessly connect to PLC and DCS control systems, enabling automatic alarms for excessively high/low differential pressure, automatic start/stop of pulse cleaning, and variable frequency speed control of the fan, significantly improving the intelligent and automated operation and management level of the dust removal and desulfurization system.

The entire unit adopts a dustproof, moisture-proof, and explosion-proof structural design. The robust casing is resistant to aging, vibration, and interference, making it suitable for harsh environments with high dust levels, humidity, and complex electrical systems in factories. It supports 24-hour continuous operation, with no easily damaged structures and an extremely low failure rate.

Suitable Scenarios

Widely applicable to various gas differential pressure monitoring scenarios in bag filters, electrostatic precipitators, and desulfurization systems, including differential pressure before and after filter bags, differential pressure at the dust collector inlet and outlet, flue gas pressure, differential pressure before and after the fan, and desulfurization duct resistance monitoring. Primarily used in flue gas treatment applications such as thermal power generation, thermal heating, metallurgical sintering, cement kiln tail, chemical tail gas, waste incineration, and biomass combustion, it is an essential instrument for industrial dust removal pipeline pressure monitoring and equipment condition diagnosis.

Maintenance Design

The equipment comes standard with a differential pressure sensor, pressure guide pipe, mounting bracket, and wiring sealing accessories, providing a complete set, simple installation, and wide versatility. It supports multiple ranges including micro differential pressure, standard differential pressure, and high differential pressure. Standard, corrosion-resistant, and explosion-proof models can be matched according to the dust collector duct resistance, airflow parameters, and operating environment. It is compatible with both new and upgraded dust collectors, desulfurization equipment, and electrostatic precipitators. Daily maintenance is simple, requiring only periodic cleaning of the pressure guide holes and probe dust, and calibration of differential pressure values, resulting in extremely low long-term operating costs.

Note

The differential pressure transmitter is designed for accurate monitoring of gas differential pressure and intelligent early warning of operating conditions. It is the core instrument for dust collection systems to determine filter bag blockage, duct dust accumulation, and abnormal air pressure. Probe blockage and leaks in the pressure guide pipe will lead to inaccurate data. Regular inspection, unblocking, and calibration are necessary to ensure accurate system cleaning logic and stable equipment air pressure operation.
