The DPC301 Modbus Differential Pressure Transmitter is a reliable solution designed for monitoring and controlling differential pressure between two points in industrial environments, production halls, and laboratories. Accurate pressure measurement is essential across various industries, as monitoring and controlling differential pressure plays a critical role in industrial and laboratory processes. To address these needs, the DPC301 is engineered to deliver precise and continuous monitoring and control of pressure differentials in your facility.
The Modbus Differential Pressure Controller features an integrated pressure sensor with two separate ports, enabling users to measure differential pressure by placing one port outside and one inside the monitored environment. The device includes four output ports, allowing the connection of 12V relays for direct pressure control in the monitored area. The transmitter is equipped with an RS485 port and communicates using the standard Modbus protocol, ensuring seamless integration with PLCs and industrial automation systems. In addition to supporting Modbus communication, the differential pressure controller features a vivid color display for real-time visualization of pressure values. Designed for panel mounting, the DPC301 offers flexible installation inside control panels, with custom panel design and implementation available based on customer requirements.
The Modbus Differential Pressure Transmitter is designed to accurately measure and control the differential pressure between two environments. The sensor features two separate ports, typically installed with one port inside the monitored area and the other outside, enabling precise measurement of both positive and negative pressure. This capability is particularly important in various applications where maintaining controlled pressure levels is critical.
One of the main use cases is in poultry farms, where creating negative pressure and lowering indoor air pressure allows fresh air to enter the facility. By installing the differential pressure transmitter inside the poultry house, users can monitor and regulate the desired pressure level in real-time. The device’s relay outputs can be used to adjust inlets within the hall to maintain pressure within the optimal range. Communication is supported via the Modbus protocol, and the system can connect directly to PLCs. By integrating the differential pressure transmitter with an industrial automation (PLC) system, users can achieve comprehensive monitoring and fully automated control of environmental conditions in breeding centers and industrial halls.
The Modbus differential pressure transmitter and controller are suitable for a wide range of industries. In addition to monitoring differential pressure, the device’s output ports allow for relay connections, enabling direct control of environmental pressure. In facilities where specific positive or negative pressure is required, essential equipment such as fans or ventilators can be managed to maintain the desired pressure using the transmitter’s outputs. If alternative pressure measurement ranges are needed (for example, other than 125 Pascal), the pressure sensor can be replaced to meet application requirements. The transmitter features an RS485 port for seamless PLC and industrial network integration. These differential pressure monitoring systems are available in various models, designed and manufactured by Behin Rayaneh Naghshineh to match customer needs. For applications requiring network connectivity, the Online Differential Pressure Measurement System (DP300W) is recommended. For portable requirements, the Portable Differential Pressure Gauge (DP200) offers convenient, rechargeable battery-powered operation, and also includes built-in temperature and humidity sensors alongside differential pressure measurement.
