ProSight Differential Pressure Transmitter Micro Differential Sensor RS485
ProSight Pressure Transmitter Micro Differential Sensor Pressure RS485 Negative Pressure 4-20mA Fan is a differential pressure transmitter designed for measuring low-pressure air and neutral gas applications. It is commonly used in HVAC systems, ventilation monitoring, cleanrooms, and industrial process control. Featuring high measurement accuracy, IP65 protection, multiple analog and digital outputs, and excellent long-term stability, it provides dependable pressure monitoring in demanding environments.
ProSight Pressure Transmitter Micro Differential Sensor Pressure RS485 Negative Pressure 4-20mA is a precision differential pressure measurement device engineered to detect extremely small pressure differences in air and other non-corrosive, neutral gases. Using advanced piezoresistive sensing technology, the transmitter continuously converts pressure variations into standardized electrical signals such as 4–20 mA, 0–5 V, 0–10 V, or RS485 Modbus RTU, allowing seamless integration with PLCs, HVAC controllers, BMS systems, and industrial automation equipment.
Its durable aluminum alloy housing with IP65 protection ensures reliable operation in industrial environments while maintaining excellent accuracy and stability over extended periods. The sensor is particularly suitable for applications requiring precise airflow, filter, duct, and room pressure monitoring.
