This pressure transmitter with open port design is ideal for monitoring duct pressures in powder air classification systems. It features ATEX/IECEx IS certification and a -15 to +15 kPa range.
The DMP331 pressure transmitter is ideally suited for monitoring duct pressures in industrial air classification systems handling powders. Air classification is a process that separates powders into different particle size fractions based on their aerodynamic properties. In a typical system, a lean phase powder stream is introduced into a classifier where a controlled airflow separates the particles. Accurate pressure measurement within the classifier and associated ductwork is crucial for maintaining efficient separation and ensuring consistent product quality.
The DMP331‘s open port design with a recessed diaphragm is specifically engineered for powder applications. This configuration allows for easy access to the diaphragm for cleaning, which is essential in environments where powder buildup can affect accuracy. The recessed design protects the sensitive diaphragm from abrasive damage caused by the powder flow, ensuring longevity and reliable performance.
This pressure transmitter offers a bi-directional gauge pressure range of -15 to +15 kPa, making it suitable for monitoring both positive and negative pressures within the air classification system. Understanding and controlling these pressure variations is critical for optimizing the classification process and preventing issues such as blockages or inefficient separation.
The DMP331 features a 4-20mA output signal with ATEX/IECEx IS certification, enabling its use in potentially explosive dust environments commonly found in powder processing. This certification ensures that the device meets stringent safety requirements for operation in hazardous areas, providing a reliable and safe solution for pressure monitoring in air classification systems.
In addition to air classification, the DMP331 can be used in other powder processing applications such as pneumatic conveying, dust collectors, and bag filters. Its robust design and accurate pressure measurement capabilities make it a versatile choice for demanding industrial environments where powder handling is prevalent.
