Product Description

What is the APT3100 Series Differential Pressure Transmitter?

The Smart Solution for Improving Efficiency in Baghouse Filter Systems

The efficient operation of industrial dust collection systems depends on the continuous and precise monitoring of filter conditions. Over time, dust accumulation inside filters reduces air permeability, leading to decreased system performance. This results in increased energy consumption, reduced filter lifespan, and higher maintenance and downtime costs.

The APT3100 Series Smart Differential Pressure Transmitter is an advanced industrial measurement solution designed to monitor filter loading conditions in real time, ensuring optimum performance in baghouse filtration systems.

What is a Differential Pressure Transmitter and Why Is It Critical for Filtration Systems?

A differential pressure transmitter is an instrument that measures the pressure difference (ΔP) between two points in a process and converts this measurement into a standard electrical output signal, typically 4–20 mA.

In baghouse filtration systems, the high-pressure side (P₁) is connected to the dirty-air chamber before the filter, while the low-pressure side (P₂) is connected to the clean-air chamber after the filter.

As dust accumulates on the filter media, the pressure difference between these two chambers increases. The APT3100 accurately measures this differential pressure at millibar-level precision, providing a clear indication of filter contamination and loading conditions.

Intelligent Filter Cleaning (Pulse Jet) Management

In conventional filtration systems, pulse jet cleaning cycles are typically controlled by fixed timer settings. As a result, compressed air is consumed even when filter cleaning is not actually required.

The APT3100 Series introduces a more efficient “Cleaning on Demand” concept:

As dust accumulates on the filters, differential pressure increases.
When the configured threshold value is reached, the APT3100 sends a signal to the control system.
Pulse jet valves are activated only when cleaning is necessary.

Benefits of Smart Cleaning Control

Up to 30% Energy Savings

Unnecessary compressed-air consumption and excessive compressor operation are eliminated.

Extended Filter Life

Filter bags are protected from unnecessary pulse cleaning cycles, reducing wear and prolonging service life.

Consistent Dust Collection Performance

The dust extraction efficiency of the facility remains at an optimum level at all times.

Wide Range of Industrial Applications

The APT3100 Series is not only used in dust collection systems but also in liquid, gas, and steam processes for flow and level measurement applications.
